I was thinking not for emergency exit lighting, but your idea sounds more correct.

[@Weather76]

These sensors are two-wire and three-wire. Those with two wires are connected in series with the load. Naturally, the lamp resistance is too high and the sensor will not work correctly. And with those in which the phase is placed in a separate wire and a relay is built in, these lamps will work well.

[@netweters]

This lamp has an IP rating of 20, which means it has no protection against dust or moisture. Therefor it's meant for indoor use only, and not in 'security' lights outside your house. That's what the symbol says.

[@BR218fan]

Yes, finally a video about this lamp! When I first saw these at a local hardware store I had to think about your video regarding the dubai lamp. I was curious and bought two of them, in 3000 and 4000 K, the colour has a green tone to it, but other than that it is a really interesting piece of lighting equipment. If it had an CRI of 90 or higher, it would be a great lamp!

[@RDCST]

The 3000K is yellowish like an old filament lamp? I'm curious about the spectrum color distribution also, but for that you need some kind of light spectrometer. How many cost you that lamp compared to the regular LED lamp?

[@Black3ternity]

How is the 4K one? Is it a neutral white as they claim or is it still "yellow / warm"?

[@foia96]

It's an efficieny thing, very high CRI leds have a slightly lower luminous output per watt, something to do with the phospores wich convert blue/uv light into visible light. Same goes with colour temperature, 4000k is more efficient than 3000k usually. The most efficient type of led is usually a 4000k 70cri type in most of leds.

[@papsdevisscher6396]

I bought both the 2.3W(40W) and the 4W(60W) in 3000K. Boy, they are disappointing. The color rendering is just... horrific. Don't understand how they would ever measure an Ra index/CRI of 80. "Eye-Comfort" (wich is written on the package) and phrases like "eye-pleasing" are just euphemisms for "horrible greenish color". Yes, they are very efficient, but that's the only positive thing about them. You wouldn't want any of those lamps in your living area's of your house.

[@w0ttheh3ll]

Finally an E27 lamp that is rated for use in enclosed fixtures! Nice. I bet they engineered this specifically to reach the "A" classification in the re-scaled EU efficiency rating (most good lamps are rated "D" right now). Prior to September last year, this lamp would've just been another A++ along with 85% of the market.

[@jaspervandenbosch3838]

The packaging even involves a symbol Philips had made specifically for lamps that fit the new best category, so I think that's pretty likely.

[@djazt.8053]

Given that the new "A" energy efficiency category starts from 210 lm/W and these lamps achieve 210 point something lm/W, definitely engineered to be part of the top category. I don't blame them for that, but would still like to see a redundant voltage converter inside like the the Dubai lamps. Otherwise that will be the part that fails first … and not after 50 years.

[@Magneticitist]

200 or so seems to be about the average I'd see in commercial led lighting I'd come across but AFAIK Cree has been putting out 250+ for several years at least. Most of my flashlights use leds which are about 250 lumen per watt at least. These are larger die power leds but still.. in a low voltage design like that it still takes about 10W to produce a little over 1000 lumens with the Crees. Some of these numbers get confusing.

@@UnlimitedRun I suppose I'm looking at it from a different perspective. Imo, these ratings are a guide for customers, and if there aren't any A rated products on the market I think that's a failure.

[@CoastalSphinx]

That non-standard HV connection adds the chip's supply current to the LED current, producing about 8 more lumens of output for the same power input and manufacturing cost. The drawback is that it won't work on lower mains voltages. In this case the designers clearly considered 240V-only operation acceptable, then optimized the efficiency on that basis. The datasheet starts with worldwide compatibility in mind (100V-240V mains) and doesn't give advice on how to maximize efficiency (since it's already "good enough").

[@theonlywoody2shoes]

Symbol indicates do not use in motion sensor lamps - I’m guessing that the leakage current that typically powers the detection circuit (via a more traditional lamp filament) either doesn’t work with the internal power supply, or the leakage is such that the lamp doesn’t turn fully off - and in doing so eventually causes the buck regulator to fail.

[@Ultrazaubererger]

Just use a motion sensor with a neutral connection and a relay if you can.

I enjoy the colour temperature decision they made. I have a set of tunable LED bulbs, and I settled on a similar sort of tweaked soft white. There's a point where the clarity of the daylight range kicks in, but without the harshness and I guess it's roughly 3000K!

[@koma-k]

3000K is common for bathroom lights here in Norway, and I've also gone for 3000K and 90+ CRI for our kitchen lighting. Other rooms are still predominantly 2700K (typical incandescent bulb). Daylight is around 6500K IIRC.

This lamps are beautiful, the same as old lamps from 1908 (two of them still work in our university). Phillips make a great product, I bought about 15 of them and changed all of my lamps to several types of these Phillips lamps. Also they don't have PWM at all (checked by Radex lupin).

[@rogerhargreaves2272]

Ah, so not quite the “Dubai” lamp, but very close to it. I recall the original “Dubai” as being more cool white as it was more appropriate for the ambiance. So it’s a little warmer and greener, so a more receptive light. I think the circuit design is quite neat. If these last as long as they claim then it is cheaper in the long run. I’m guessing the symbol on the box means it’s not suitable for P.I.R use in passageways.

[@jdlech]

I searched the internet for an inordinate amount of time. Phillips has a web site for the symbols it uses for various medical equipment. But the symbol is not found there. Probably because it's only for medical equipment. But your explanation is the best I've read. But there begs some question about its use - is that it's not suitable for lighting the area covered by IR detectors? Will it mess with IR detector functionality? Or maybe even ruin one after long exposure? I think our friend Clive might have to investigate.

Good to see that they are using a lower colour temperature than the Dubai ones. The cold and very cold white of the Dubai lamps limited my use of them in the UK. Price isn't extreme as I'm pretty sure they are paying extra for the high efficiency LEDs (selecting the highest output binned ones). 210 lumens/watt isn't to be sniffed at especially when you consider the Stokes shift of the phosphor to give the 3000K colour temperature.

Back in the days of incandescent exit lights, some times we would use 220 volt lamps for long life or we also wired the 2 -120v lamps in series. Also some of them were candelabra bulbs with a diode for longer life.

[@kwinterburn]

Candelabra bulbs lovely made without an internal fuse so BOOM and shattered glass everywhere, people couldn't understand they weren't SES or MES just somewhere in between an E12 not a E14

My Philips & Osram CFLs are still going strong, so it will be at least a year or 2 before I need to buy any LED bulbs. Interesting video on the new lamps.

Assuming it’s got decent color quality I’d be tempted to try and get some of these in the US. I should be able to drag them along with me for most of my life

@@handlesarefeckinstupid I mean I could use 240V I’d just need to run circuits for that

[@FerralVideo]

I've got a case of those rough service long life bulbs. They're nameplated 5000 hours, and indeed don't put out nearly as much usable light for the 60w as one of the myriad "normal" bulbs I've got clattering around. My coworker (before they had LEDs and CFLs) deliberately bought a 240v bulb to put in a 120v socket to just leave on all the time. It's still there and probably still running. These days I'd use one of the LED lamps you've featured on this channel with the 0.5w hack, for example. Might do that for the light over my front door in the living room, actually...

[@stevebabiak6997]

At 13:40 the very high value 2.2 Megohm (x2) resistors are discussed. Given that you have an L-C circuit there that can “ring” (resonate), and diodes can only conduct in one direction, I think those resistors are there for snubbing / dampening. But there might be other opinions on that …

[@craignehring]

These types of lamps are very interesting Clive, thanks for another great video

[@xhobv02]

I have a few of them, they are very efficient BUT the CRI is just 80% and the color has a terible green tint which is noticeable on white walls. I ended using a newly developped Solhetta filament IKEA bulbs - the are just a bit less efficient (2.9W instead of 2.3W for the 470 lumen variant) but it has CRI 90, no green tint and is 50% cheaper.

[@amikawashima9191]

Products with exactly the same packaging and lamps are also sold in China, but the Chinese version is only 200LM per watt (4W bulbs provide 800LM). I don’t know if it is because of the difference in voltage or the difference in measurement methods. But these light bulbs are very cheap in China, only selling for 30RMB, which is equivalent to US$4.20.

[@amikawashima9191]

This lamp is not cost-effective in China. Although it saves power, it has an obvious color cast, the light is not smooth enough, the CRI is only 80, and the spectrum is not as good as that of sunlike LED lamps in the price range.

[@neutronpcxt372]

Personally, if this light design was available in an R9080(90CRI minimum, 80R9 minimum), I'd just throw money at it honestly. Say, I don't know if I'm mistaking something, but the glass on the bulb seems to have an AR coating of some sort. This probably increases the optical efficiency of the light nicely.

[@electriciants7927]

Looks like the symbol is telling the consumer "Not suitable for motion light sets". Great video!

[@blacksmock445]

Regarding colour rendition of early flourescent tubes, I remember having fish & chips in Cowes, Isle of Wight, in the early '50s. They looked green in the flourescent light.

Same with bread. I always used bread as first indicator for CRI.

[@68MalKontent]

Yup, a CRI of 80 is really shitty in 2022.

[@TechSY730]

Wow, I did not expect this. Phillips defied the "lightbulb psuedo-cartel 2.0", and actually released the high efficiency long life Dubai lamp (or close enough) to everyone else. That...is actually praiseworthy. Genuine thanks, Phillips. (Now let's hope they can fine tune CRI and "less tinted green" soft white for future generations of the bulb)

[@idjtoal]

Maybe they're aiming for the short-term profits with the £11 price? But yes, it's a real break from tradition to actually sell something that'll last, can't possibly hope that things have substantially changed though.

[@andrewfidel2220]

I bought some 50W driverless COBs to put in my torchier to replace a 300W tungsten halogen bulb, they have that same 3000K green/yellow hue. It's a bit jarring if you're used to 2700K bulbs as 300k doesn't seem like much but it's a massively different phosphor setup and light quality.

[@SteveDurbin]

Could the circuit change be to allow for 230V supplies compared to 110V? Given the drop is to 125V seems a possible change for differing markets?

[@SeanBZA]

Yes, seeing as the controller is designed for universal voltage, lowering power dissipation both improves efficiency, and also makes the tiny chip last longer as well.

[@galfisk]

Also if the chip should fail short, the lamp will keep working (ish). No short circuit path exists.

[@iamjadedhobo]

Exactly what I thought. The datasheet probably has an electrical specification somewhere for what the HV range is. This might specify 100V to 350V to cover all areas in the world, but the schematic might be for 90 ~ 110V regions (US and Japan).

[@SeanBZA]

@@iamjadedhobo Yes they have limits for the boost voltage for different regions, but likely only show the one, unless you ask them for the full datasheet, likely only on a NDA agreement.

[@zakmcrofl967]

That is such a B.S. PR response. I am very sure they also see the green as a flaw, there is no way this was deemed preferable. I would guess it was a trade off in order to achieve the new A rating at all costs, now they pretend it's a good thing (until they finally fix it hopefully someday)

[@1kreature]

Last symbol is "do not use on sensor" so not for turning on and off often.

[@MatSmithLondon]

Philips really need to up their game with dimmable, high CRI lamps. They do make some, especially the "dim to warm" or whatever the branding calls it now. But they are not as ubiquitous as they should be! i.e. they are usually sold out at Toolstation / Screwfix, and they aren't available in all the formats you might hope (GU10 / bayonet / screw / golf ball / candle etc...) Also CRI is never advertised, which is a shame.

[@davidfalconer8913]

Commenting on LED " colour " , some latest microwave ovens use a ( more robust ) twin " filament " LED lamp , a direct replacement for the tungsten types ( which always fail ! ) .. when powered outside the oven , they give a trendy golden yellow light ( almost similar to LOW pressure sodium street lamps , remember them ? ) .. I am guessing this makes your rotating pie look more appetising ( ? ) .. very peculiar when used as a room light ! ... QED ...

[@NetRolller3D]

Looks like Philips is coming out with 75W & 100W-equivalent versions of this, as well as frosted and E14 candelabra versions. Right now, these only seems to be actually available from a single retailer located in Slovakia, but all of Philips's EU websites seem to list them.

[@jamesdagmond]

They need to get this in the US already.

[@fritsriep3830]

They are now available in the US. I was able to order online through Walmart of all places. The bulbs are amazingly efficient, but the color of light is not great in a home (color has a enough green to look odd in a residence).. I prefer the color of the Philips 2700k Warm Glow on a dimmer, but use 8.5w rather than the 4.5w of the Ultra Efficient. Ideally, I'd like a dimmable version, 2700k, warm glow, and would give up some efficiency as needed to get better color and longer life.

[@guitarfreakfalko]

I really don't like the greenish tint they give off. Philips could have done a better job if they'd wanted. R9 is negative 10, meaning that things that should appear red seem more pale and dimmer than with regular led or incandescent light bulbs. You can find that information and a picture/curve of the light spectrum in the EU - Product data sheet.

Thanks, Clive. Very interesting. I am wondering if the glass globes have a vacuum in them, or maybe some type of gas - or just regular air?

[@bigclivedotcom]

Possibly a gas like helium to assist thermal transfer.

[@Nicholas-f5]

@@bigclivedotcom helium would be costly, perhaps nitrogen or inert gas?

[@jamesdhooker]

@Banter Maestro2 Helium-oxygen is the preferred filling in these. Although Helium will leak through certain glass types used in other lamps, the rate of diffusion through the soda-lime-silicate (Philips PH241 glass) and the strontium-barium-silicate (Philips PH360 glass) used for these lamps is exceptionally low. The most critical area is the glass-to-metal seals that carry the electrical current into the bulb. These are made from a borated copper sheath brazed to a 42% nickel-iron core to match the thermal expansion rate of the glass, and helium can diffuse along microcracks in the brazed interface. Even so, when bearing in mind the leak rate along the wires plus the rate of diffusion through the 0.6mm thick glass envelpe, I estimate that the half-life of the helium filling is about 75 years. This is well in excess of the rated life.

[@swedishspymuseum]

As several have pointed out, the symbole means that its not suiteble for motion detection fixtures (many on/offs) like drive way lights. The IP rating is not unusual, few lamps have any significant IP ratings since they are usually not "naked" but inside an IP rated fixture. However, as stated, the way they have implemented the circuitry, it is not suitable for frequent "on/off", hence the symbole...

[@johndododoe1411]

Indeed most wall sockets are IP20 because they have holes in the front that let metal pins touch live circuits.

[@johngarritzcx6733]

I had this lamp on for a while it is lukewarm tot The touch so it could be used in closed luminaires/ fixtures 😊😊

[@TheEulerID]

By my calculations, one of those bulbs would save about £1 per year per daily hour compared to the more usual ones at the same output at current UK electricity rates. So if a bulb was used on average 4 hours per day, that's about £4 a year and any extra cost would pay back in a year or two. However, if it's only turned on occasionally, then it's going to take decades. The lesson here is to put the most efficient bulbs into the fittings which are used most if you want to optimise your saving and expenditure. Note, I've not considered any savings from the bulbs lasting longer, but that might not be so important for those which aren't used a lot anyway.

[@crimsonhalo13]

The mystery icon: could it be "do not use for motion detector lamps?" The on and off cycling might be at issue if that's the case.

Clever! I do so hate the end of life intermittent flash of many LED lamps

Hey Clive, I would love to see a a project that steps up 5v to a suitably high voltage to run these efficient lamps off DC in a standard socket, I would love to convert my desk lamp to USB that way so it can be run off a powerbank

[@charleslambert3368]

You can get 12V E27 (screw) bulbs for use on busses, caravans and houseboats. It's easy to step 5V up to 12V using a boost or buck-boost converter (cheap on amazon). I can't guarantee that a usb charger will be able to put out enough power for a bulb rated to more than a couple of watts. You might be better of running the converter directly from some 18650s or an rc hobbyist lipo pack.

[@vimicito]

@@charleslambert3368 with 12V DC you could even use a USB PD powerbank, no dedicated boost converter needed that way. All you'd need is a little 12V trigger board and a USB-C cable (both ends, though some supplies can do it on USB-A too). You can get those trigger boards very cheaply in the usual places (Ebay, Aliexpress etc).

[@Mr.BrownsBasement]

Icon: I think "Not suitable for Emergency exit luminaire". I thought about what you said about using the chip in a non-standard configuration. Philips may have got a copy of the internals from the manufacturer and/or consulted the engineers at the manufacturer or simply got a custom version of the chip fabbed. After all, they Philips would be ordering enough that it would be worthwhile. I did a quick check and it doesn't look like this lamp is available in North America yet.

[@Peffse]

I wonder how the heat is. My enclosed overhead fixture kills everything so fast. This might be a long-term fix!

[@fishyerik]

As heat is the energy that isn't turned into visible light, that lamp produces much less heat per watt it uses compared to "common lamps", and as it produces more light per watt, the heat for the same amount light is even more reduced. Heat is unlikely an issue with those lamps.

[@Peffse]

@@fishyerik in theory, yes. But it's not the filament that's cooking in my enclosure. It's the board from component hotspots. I'm not sure if driving twice the filament at half the power is going to change anything on the board. Won't stop me from buying a bunch, though.

[@fishyerik]

​@@Peffse Driver power, therefore also heat generated is included in that total power draw. There's not much room for heat generation when it produces 840 lm from only 4 W, filament and driver combined. Sure, if it was very poorly designed some component could be prone to overheating anyway, but it's unlikely to be the case. If those also die within a short time, there's probably something else that's wrong.
