The GL-BR30-9 Warm White LED Light Bulb (hereinafter, probably just called a "light bulb" or even a "bulb") is a fantastic new LED floodlight bulb with a very pleasing warm white color to it.

It is intended to be used as an indoors-only flood light; the viewing angle is published as 120°.

The light source is nine high-powered warm white LEDs; it is not yet known who the manufacturer of those LEDs is.

The bulb is ready to use as soon as you receive it. Screw it into any standard medium base 110 to 130 volts AC receptacle.

Then, to borrow a phrase from a TV commercial (somewhat modified here), "turn it on, turn it on!"

For the purposes of this web page, I used a portable trouble light to power this bulb with.

***VERY IMPORTANT!!!*** DO NOT under any circumstances screw this bulb into a fixture controlled by a dimmer switch, whether that switch is on the wall or on the fixture itself. It WILL fail fairly quickly, and possibly quite spectacularly so, if this is done.
You don't want baby Emperor scorpions or Mourningcloak butterfly caterpillars (larvae)...I don't want an unwanted fire.

Since this product is designed to be operated from 100 volts to 240 volts AC at 50Hz or 60Hz, I do not have to tell you which part to remove, huck into an open-pit zinc or gadolinium mine, what kind of batteries need to be flushed away, and then rather emphatically tell you not to do that stuff.

This is an LED bulb, not a flashlight meant to be thrashed, trashed, and abused. So I won't throw it against the wall, stomp on it, try to drown it in the toylet bowl or the cistern, run over it, swing it against the concrete floor of a porch, use a medium claw hammer in order to bash it open to check it for candiosity, fire it from the cannoņata, drop it down the top of Mt. Erupto (I guess I've been watching the TV program "Viva Piņata" too much again - candiosity is usually checked with a laser-type device on a platform with a large readout (located at Piņata Central), with a handheld wand that Langston Lickatoad uses, or with a pack-of-cards-sized device that Fergy Fudgehog uses; the cannoņata (also located at Piņata Central) is only used to shoot piņatas to piņata parties away from picturesque Piņata Island, and Mt. Erupto is an active volcano on Piņata Island {In the episode "Les Saves the Day...Again", Paulie Preztail says "Hey, ever wonder why this park's called 'Mount Erupto' anyway?", then Franklin Fizzlybear says "I think its an old native term. Means 'very safe.'"}), send it to the Daystrom Institute for additional analyses, or inflict upon it punishments that flashlights may have inflicted upon them.

This bulb is made primarily of plastic. So it CAN become broken if dropped, thrown, or otherwise abused. Handle it as you would an ordinary household light bulb, and it shouldn't give you any guff.

Since this is a light bulb with a set purpose (it's a light bulb gosh darn diddly-arn it!), I don't have a whole lot more to say about it.

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

The viewing angle is listed as 120°, so this is a true floodlight bulb.

When this bulb is in operation, the temperature of the metal heatsink can rise to 50°C (122°F) or even 60°C (140°F); this is perfectly normal, and is nothing whatsoever to be concerned about.

There is a delay of approximately two seconds from the time you energise this bulb until the time it actually springs to life; once again this is normal and is nothing whatsoever to be concerned about.

Measures 140,100mcd on a Meterman LM631 (now Amprobe LM631A) light meter.

This is a wide viewing angle source, and if I've said this once, I've said it 2,458,770 times:
Wider viewing angles always, always, ALWAYS equal lower measured mcd values!!!

That darker spot at the left-center in this analysis that queered the test (and caused that squarish dip visible in the chart itself) is a defect in the ProMetric's CCD imager, and cannot be compensated for.

Test unit was sent by my contact at GlacialLight on 02-04-10, and was received late morning on 02-12-10

Product was made in China.
A product's country of origin really does matter to some people, which is why I published it on this web page.

UPDATE: 00-00-00

Economical to operate
Warm white color may be more pleasing to the eye of some viewers
Can be used on 115 volt and 230 volt electrical systems -- basically worldwide

Not dimmable -- that's what nocked that last 0.05 star off
