Duro-Test Fluomeric 750watt Self Ballasted Mercury Vapor Flood Light Bulb

[@Sparky-ww5re]

A more accurate term for this awesome bulb would be cool white incandescent. I found this in my 2006 GE lamp catalog and the initial lumens are 14,000. 11,200 mean lumens, 3900K 50 CRI and 16,000 hour rated life. That averages out 15 lumens per watt. 16,000 hrs is short for a mercury vapor lamp and is almost certainly limited to the life of the filaments. Some mercury vapor lamps have been in service for over 20 years and lasted much longer than the manufacturers quote.

That thumbnail got me 😂

[@douro20]

My old GE SBMW sunlamp has a tapped ballast filament with a snap switch which opens part of the filament after starting. I believe it is used as a starting aid. The popping sound it makes can be a bit unsettling at first.

[@randacnam7321]

That switch actually shorts out part of the ballast filament once the lamp has warmed up enough, as the mercury discharge tube only drops around 20V right when the arc starts.

[@cherrysdiy5005]

This thing is massive! That startup is beautiful. I don't think I've ever truly appreciated that before, but now I do! Not to mention, no one gets to see a self-ballasting lamp do it's thing everyday, and most wouldn't know or give a second thought. Spectacular engineering, and thank you for the video!

[@Parrot175]

Thank you, you're welcome!

[@GothGuy885]

Awesome Bulbs! 👍

[@Parrot175]

Thank you, glad you enjoy them!

[@mikejordan4899]

120 volt self ballasted mercury lamps have a heater filament next to one or both of the electrodes that is in series with the ballast filament, or filaments, and a thermal switch. The heater facilitates in vaporizing the mercury which will allow and arc to be established in the arc tube, Once the desired temperature is reached, the thermal switch will open allowing the arc tube and ballast filament to operate in series. The heater filament will also be turned off once the thermal switch opens. 240 volt self ballasted mercury lamps do not have the heater filament as the main voltage is high enough to start the lamp. These 240 volt lamps do have a starting probe and resistor just like a regular mercury lamp.

I love the expression on your face in the thumbnail!

[@sieandknsproductions3491]

Self ballasted Mercury vapour bulbs look more like metal halide bulbs at full brightness

[@Sparky-ww5re]

Obviously because the filament in a self ballasted mercury vapor adds some reds to the bluish mercury vapor color bringing the roughly 6000K closer to the 4000K typical for metal halide.

[@volvo09]

that is a super cool bulb! must be one of the highest wattage self ballasted bulbs.

[@tearimakatekeimoa1675]

I had one in our old houseand that qas 1000w

[@albear972]

Wow! That light bulb is simply spectacular! Very awesome find. The construction of it looks magnificent.

[@photonik-luminescence]

WOW, that is a big a selfballasted mercury vapor bulb. That is a great light bulb. Didnt know there eaven were selfballasted mv bulbs of that wattage. Great video !

[@randacnam7321]

These were made as big as 1,750W.

[@liamslightsandbulbs]

What an awesome bulb! So crazy your phone overheated. We love this video!

[@rayfluorescent7483]

I agree with you totally awesome Lightbulb from a super great company that you don’t hear much about anymore

[@Parrot175]

Indeed!

[@Kennephone]

Be careful with that in a small space, these things put out alot of uv.

[@Jefflantern483]

Now that is a light bulb! 🙂🙂

[@strashinsky]

That's one bad ass bulb bro! And I said the same thing at the same time as you about the bulb being a "beast" 🤟

[@SmokeAlarmsandmoreofMYstuff]

Mogul base? Or medium base?

[@Sparky-ww5re]

Mogul base. Lamps over 300 watts are required to use a mogul base. Many HID lamps over 100 watts use mogul. The largest HID lamp with medium base is a 200 watt metal halide. The smallest HID with mogul base is a 50 watt high pressure sodium.

[@badreality2]

It needs to be that shiny, to dissipate heat.

[@Notbluefox]

That was incredible.

[@kingofthecarwashes6724]

I like those SMC Lagunas.

[@worldwidehidcollectorusa3519]

The Duro Test reflector lamp that you have here has an R57 envelope just so you know. The Philips Kleen Beam lamp has an R60 envelope. In addition, R57 incandescent reflector lamps were available in 500W, 750W, and 1000W ratings while R60 incandescent reflector lamps were available in 750W and 1000W ratings.

[@bichela]

In the modern age of LED, is there an LED model? Love to get a few self ballasted bulbs for my yt studio. The smaller a21 sized 175 watts would be fine.

[@redstonecommander5190]

This singing is extremely bright, almost a spice, looking at the sun, even that the reflection on the ceiling and the walls were uncomfortable to look at. And the heat ….. just those two electrodes were just staggering%! It was almost quite powerful enough to admit the light of day and direct sunlight

[@washingtonstatetransportat7938]

Did you happen to buy this at the Tacoma Habitat for Humanity store? I remember pricing some bulbs similar to this a while ago not sure if there the said bulbs tho, cool knowing they went to a good home at least.

[@Parrot175]

Indeed, I did pick these up from the Tacoma ReStore! Thank you for putting them out on the sales floor, they are a find of a lifetime!

[@The_WJC]

@Parrot175 this is the 2nd highest wattage bulb you've ever showed us

[@chriscooper1905]

Breast! I have HYTRON 750 watts SBMW so bright!

[@Parrot175]

Awesome!

[@TheNovum]

beast of a lamp..

[@fluorescentlightman3008]

That’s really cool

[@Dekko-chan]

I just found a 250 watt integrated ballast mercury vapor lamp in a bunch of moving boxes upstairs. Its also really friggin bright.

[@CarGuy-uz7gz]

If my light bulb socket to outlet adapters could handle 900w instead of 660w, I would use this

[@CarGuy-uz7gz]

Accidental face reveal

[@NicholasthefanMan]

He did face reavals mutable times

[@Anthony_The_Chicken_Licker]

Nice 💡

[@LampLuminance]

Yep

[@inactiv4822]

What is the lumen output compared to a standard mercury vapor lamp?

[@djm5k]

Industrial strength lamp, that’s for sure!

[@kerriryan1320]

Such light fixture does that bulb go into? Please reply!

[@djm5k]

They were mostly used in high bay downlight applications to replace high wattage incandescent bulbs. You would find these in warehouses, factories and other industrial facilities with high ceilings. They were designed to be used in “base up” installations.

[@stphinkle]

I wonder what these were used for.

[@cgschow1971]

Factories, outdoor flood lighting for security and parking lots, and zoo exhibits (primarily reptiles).

[@acpineda7263]

I have a self ballasted mid base mercury vapor bulb

[@grantyentis5507]

Feeling jealous!! I love this light!!!

[@HIDLad001]

Where did you get this?

[@CadeRankin2006]

!WOW!
