Berkeley Reclaimed Light LED Light Bulbs, retail $ (Prototype/not for sale)
Manufactured by Berkeley Reclaimed Light
Last updated 09-07-10

Reclaimed Light LED Light Bulbs are cylindrical devices that screw into any United States medium screw base light receptacle (E26), and are powered directly from 110 to 130 volts AC 60Hz. They each use 12 super high-brightness LEDs, and are designed specifically to be used in light fixtures with diffusers or shades.

For testing purposes, I was furnished with a cool white unit and a warm white unit.


The bulb is ready to use as soon as you receive it. Screw it into any standard medium base 110 to 130 volts AC socket that would normally hold a standard incandescent or compact fluorescent household light blub.
Then, to borrow a phrase from a TV commercial, "plug it in, plug it in!"

For the purposes of this web page, I used a floor lamp with shade to power these bulbs with.

DO NOT under any circumstances screw these bulbs into fixtures controlled by a dimmer switch, whether that switch is on the wall or on the fixture itself. They WILL fail fairly quickly, and possibly quite spectacularly so, if this is done.
You don't want rats or luna moths...I don't want an unwanted fire.

Since this product is designed to be operated from 110-130VAC, this section can be skipped.

These are LED bulbs, not flashlights. So I won't slam them against a steel rod, try to drown them in the john, stomp on them, run over them with a 400lb electric Rascalator thing, throw them at a wall-mounted porcelain urinator to see if they smash open (the bulbs, not the urinator), or subject them to other indecencies that a flashlight might be subject to. These bulbs are made primarily of plastic with plenty of metal surface to act as heat sinks for the LEDs. If they are dropped, thrown, or otherwise abused, they CAN become broken. Handle them as you would ordinary household light bulbs, and they shouldn't give you any guff.

The two bulbs I received use Cree XLamp LEDs (cool white) and Nichia Jupiter Jigsaw LEDs (warm white). Both of these LED types are high-flux high-powered LEDs, not SMD, 3mm, 5mm, 10mm, or "spider" LEDs.

The light output appears very smooth in nature, and gives a full 360 in the X (horizontal axis) and ~180 in the Y (vertical axis) of light coverage; lending itself very, very nicely for use in lamps with lampshades.

These bulbs are dew-resistant at minimum, and can be used in protected outdoor fixtures - "protected" in the manner that rain or snow cannot directly enter the fixture.

The bulb's temperature was measured at 157F (69.4C) after fifteen continuous minutes of operation. This is a perfectly normal temperature for these bulbs, and is nothing whatsoever to be concerned about.

The base of these bulbs is E26 (26mm), which is the standard medium screw base that is used by household light blubs in the United States.

Measures 59,100mcd.

Both measurements were taken on a Meterman LM631 light meter.

Yes, that really *IS* a toilet bowl back there.

Test units (prototypes; one warm white unit and one cool white unit) were sent by P.M. of Berkeley Reclaimed Light and were received on 02-08-06.

UPDATE: 03-19-06
I have added spectra of the two blubs to this web page.

UPDATE: 06-25-06
It has become evident that for some reason, these bulbs do not work well - if at all - in 3-way lamp receptacles. These bulbs have a normal looking base (a medium screw base, an insulator, and a "button" contact at the bottom), so I don't know what the problem is here.
