[@Decebal_of_the_Getae]

Hello. What is the lighting efficacy of the LED strips presented and do they meet the legal requirements? Main problem as far as I am aware is meeting the legal efficiency requirements, as some COB strips on the market are effectively illegal.

[@TradieTrev]

That's just crazy using an ip67 seal quick connector. I've always rubbished those things, but clearly you've got a working example!

[@thattoolguy9432]

Nice to see the Macau @ 90cri, might switch suppliers depending on availability , for anyone wanting to dim led strip in a permanent way, i use an adjustable voltage power supply by Meanwell, they even make them din rail mounted... nice to see you guys hitting on Cri.. colour in the video shows it better than previous

[@kennmossman8701]

Dimming can be done via adjusting the voltage or by using PWM. PWM might be preferred for low light levels as the color is better preserved.

[@WhippyEU]

I was told that COB LED's die faster, but I've had these integrated in my kitchen larder for over a year now and they're brilliant!

[@efixx]

LED life depends upon lots of different factors from mounting arrangements to drive current. In a kitchen used a few hours a day I wouldn’t expect any problems for a long time. (Assuming they are installed properly)

[@hauptuhrdotnetblog6700]

@@efixx I believe there is a quality issue too often with certain LED products. Especially with LED “bulbs”. Incandescent bulbs used a lot more power but for disposal they were just a bit of glass, a tiny amount of filament and some tin. Now a modern LED E27/B22/GX53 light is full of electronic components in addition to the LEDs. Every one that’s failed on me personally has failed due to the additional components failing. The LEDs are fine when tested on a lab power supply. What gives me the -hits is how much e-waste these things produce over a traditional incandescent bulb. Domestic lighting was never the major demand on our grids back when we had incandescents. Now we save with LEDs but I feel that we are fooling ourselves thinking that these modern LED bulbs provide a net *environmental* benefit over incandescents. I’m confident they don’t. They are fantastic technology but my issue is purely the environmental claims and justifications for these things. When it comes to daily living though, I’ll admit that all that goes out the window with present UK electricity pricing which is effectively a national emergency considering it’s impact on those that can least afford it. The solutions demonstrated in this efixx video look great. If the driver fails, which in my experience it is more likely to do than the LEDs, it can be replaced individually, thus minimising the amount of e-waste to the driver and not the entire lighting system itself. For the purposes of full disclosure, I use a “vintage” kettle with a replaceable element.

[@alfredoandroid357]

Just what I been looking for , thanks 😊 🙏

[@dadanum8443]

Fantastic video series - all very informative and thoughtfully done

[@merlin1346]

With the power connector fitted on the end of the COB is it then possible to trim off the white borders either side all along for the entire length? will it still work?

[@AlexWillmer]

What is the aluminium channel you used for the strips on the ceiling? Thanks.

[@DjShadowsound265]

How flexible are these? im thinking of doing tight corner with these COB strips, will have any impact on the joints or is it pretty flexible on a flat surface to do tight 90 degree corners?

[@AlexeiTetenov]

Thank you for sharing!

[@Robbe1984]

Can you bend these strips in an 80-90 degree angle? I want to put a single strip around my wooden head board behind our bed.

[@HeathenGeek]

nice, but can they work with 'regular' (V-Pro) dimmers?

[@VintageVaughnVehiclces]

I use this LED strip same exact product behind my reflector panel of my 1976 Ford LTD if you remember those I had that big Square red reflector on the trunk so you run that LED strip all the way around and you glue it down with Flex Seal there's a piece of foam rubber back behind that reflector and you paint that with Flex Seal and then glue down that LED strip and then wire it to a dedicated brake light source by running a wire all the way from the end of the trunk lid up to the brake pedal and Connect into the switch so it won't blink when you turn on the left or the right turn indicators by tapping into one of them it's an awesome application it turned out fantastic and old cars rule when you put in 21st century updating.

[@kenreynolds1000]

I had to deal with this extensively with some aerospace LED strips from a couple of generations ago. Any diffuser that isn't water clear has losses They basically mix in stuff like chalk to make white diffusers and that is just going to increase loss.

[@Gk2003m]

I’d heard COB recently… I’m on Hue color lights and light strips. The light strips themselves are never visible as they are at the backs of high shelves or under cabinets, so that solution works very well. They are plenty bright. And not having so many LEDs, they don’t generate as much heat and therefore don’t need ventilation. But I do have a potential application for a COB color light strip. We’ll see how it develops

[@keshavoncloud9]

Can you bend a cob strip like you do a regular LED strip?

[@daviddobiesz]

No corner or 45 degree pieces available? Im going for seamless.

[@othoapproto9603]

It's about time. How long will it be before they make an Edge version? They also need to move the solder pad under/on the back and trim the strip down to just the lights with no white edge.

[@Dog-whisperer7494]

I want to use them on my loom beam. I get the strips and how they work, but I just don't know how to electrify them. This loom is in the middle of the room and would need a long cord? What components do I need? For the sake of conversation, let's call this loom beam 5' in length and I would mount the strip on the underside of the beam to light my handiwork. Thanks for any guidance you can offer

[@christastic100]

With no dots they will all be dashing for them. I have wired the traditional led lights as a ring because of voltage drop to double up the continuous length.

[@locrien8888]

Foam crown molding with recessed color temperature adjustable led strips are my favorite way to light up a room. Indirect light is the best kind of light.

I always use Non Waterproof and put them in Acrylic Tubing for the Under glow on my 69 Dodge Charger back in 2006 there isn't any gaps as I am using the 3528 led strips when they shine on the ground, but maybe it is because of the, Acrylic Tubing making it like a tube light but 17 years later and they still work fine, now I am kind of interested in those COB Led light strips they look good it doesn't matter if they're are non waterproof as I will be placing them in the Acrylic Tubing again for another project.

I've been using COB lamps for years, GU10 mainly and I was under the impression in related to the make of the diode from the glass type the original LED lamps were made of to the yellow coated replacement, as opposed to being a continual strip of diodes. How do you guys deal with the problem of single insulated cabling, (both ELV and 230V), usually where they go into the driver, like that app controlled on the bench you showed, or the 5 strand wiring that gets soldered onto the tape on an RGBW setup?

[@ShaneSiKBoYBrown]

I've literally installed this today and had the same issue.

[@efixx]

All of the single insulated cable here is on the LV side of the driver. The dimming modules have 24VDC inputs

[@ShaneSiKBoYBrown]

What is the solution to drivers which have 230v terminals at one end and 12/24v at the other? I've thought about putting the driver in an enclosure but surely this will impede heat dissipation and likely shorten the drivers lifespan?

Soldering is the best way to permanently connect strips. Practice first if you are novice.

[@angelarolski1554]

What was the wall switch controlling - was it dimming only or change or colour from cool white to warm white? Do you know of any product that can do that as I am on the search for such product for awhile already

[@efixx]

This was just for dimming on a single channel. Other versions are available for multi channel and I have seen dedicated drivers and controls for colour tuning - I’ll see what we can find.

[@angelarolski1554]

@@efixx Great. Thank you. I've seen controlers where you can choose a colour tuning, but I haven't yet seen a product to that can be switched or work with a smart system. I had a client struggling to decide of colour lighting he wants as he preferred natural light during the day and warm light evenings. Lighting with switchable colour tuning would have been perfect. I'll have a look at Robus product. Maybe they have or a working on something similar.

Can you make a perfect right angle with continuous light?

its tricky - unless you are using a deeper extrusion and diffuser cover.

[@kennmossman8701]

arrange so the distance between them makes the distance between LEDs consistent. Set them so the polarity does not have wires crossing. {yes, you have to solder - using short wires}}

[@Simple_Simon_UK]

@@efixx Thank you for replying. It's odd that ROBUS have all sorts of connectors but not a 90 Deg one - An obvious real-world requirement. I am looking to use the COB LED's on a stair project. I have 3 flights of steps - A 9 Step, 11 Step & another 9 Step flight. I am not exactly sure how I'm going to be able to control them all, as each step is 1.2M wide, with a 0.3M depth, and I want the COB LED strips to form a long "L" shape on each step - Hence the need for a 90 Deg join. Looking at the power requirement, it appears I will need 2 x 200W drivers for the 9 Step flights and a 250W for the 11 Step flight. As much as I would love to be able to create a Run-Way motion effect, I don't want to have to individually address each step with a wire - There would be far too many wires. As it is, I can probably hide a pair of wires for each flight to run to the drivers. I was thinking of getting an Arduino or a Pi involved, but going the KISS route might be best for my first project of this kind. If you have any tips - They would be most welcomed.

[@yuecho2050]

This effect can be achieved with our side glow COB light strips, contact me for details.

[@nickwraith312]

Good video, but the additional LEDs don't make it any brighter. The brightness is a function of the Lumens/watt and the wattage. Having done some research, it appears that typically, the COB strip is less efficient than many stand alone 2835 LED strips.

[@TheGeezzer]

The great thing is, lots of light output for small wattage output!

[@LEO-xo9cz]

I thought all led strips were cob hence the need for constant voltage instead of constant current?

[@efixx]

The led chips are mounted directly to the circuit board - COB - regular LEDs have the chip mounted in a package including phosphor which is then mounted to the LED strip circuit board.

[@PinataOblongata]

​@@efixx I assumed that colours coming from pigments in paint would be the same as colours coming from any other source, but it seems you are correct, pigments reflecting certain colours are different to light sources of different wavelengths - I don't exactly know why this is the case, but I've learned something - always assumed you needed RGB to make white, but apparently even Newton knew you could do it with blue and yellow.

[@kanga22883]

Why does it have to be 24V, this would be great for a theatre project, but I need to run it off a 12V battery

[@efixx]

higher voltage = lower current and lower voltage drop. you could connect 2 x 12v batteries in series.

[@merlin5476]

Some manufacturers do 12v led strips which are some of the best & brightest I've used. I have soldered to the wee copper pads with a tiny soldering iron & used the remainder of the strip in my van & in friends vans too, so much better than the silly wee bulb in the back of a transit .

[@kennmossman8701]

because of the Vf of the set of LEDs; more LEDs in a set means higher Vf which requires a higher power supply voltage. You can use a boost voltage converter to 'boost' the voltage from 12V to 24V
