do these bulbs emit a full spectrum of light?

6500k = to natural daylight. Great for growing plants. I use them for aquarium plants.

I don't think they are. Actually, I highly doubt it. I've used them in regular light fixtures and have been very pleased with them. Their output is high, although I haven't measured it in lumens. Color balanced seems spot on, compared to natural daylight. I put them in a softbox and they work quite well. Regards, Steve

They appear to be. The tops of the bulbs are faded to the point where you can't see the amount of wattage but they are bright like a 100 watt bulb.

These are full spectrum lites which means it give off light closest to the daytime sun. I use the equal to 100 watters for over diningroom and in sun room in winter time. I have no complaints.

These bulbs produce a nice crisp white light with no bluish tint. They colour shift a little about after 30hrs and become slightly whiter. Performance is great. I have uploaded a pic for you, hope it helps.

Not very well. These are designed to output a constant light level from about 10 volts to 30 volts DC. From 10 volts to 7 volts, this bulb will go from full brightness to so dim there is just a tiny spec of light on the face of the LED's. Anything below 7 volts, they are totally dark.

Yes. The lamps arrived with compact fluorescent bulbs. They seem to be quick start with immediate full illumination.

As far as I know, no. However, these are LED lights. Basically, LEDs do "not" go out the way regular bulbs do. The LEDs are not lightbulbs, but diodes (the D in LED) that are integrated on the circuit boards.

Not that I know of although they can be programmed to turn on when you come into the room. They are pretty cool bulbs!

Short Answer: Yes. These are halogen bulbs, and unlike compact fluorescents or LEDs, the light output can be managed with a rheostat (dimmer).

None that I am aware of at present. I installed my Full Spectrum Light Bulbs (ALZO 45W CFL) in light sockets without a globe or shade (not my original plan). Used in this fashion they throw a lot of light as long as you aren't too concerned about appearances.One is mounted horizontally and another vertically. Both have been in service since the beginning of this year without any problem.

I am not sure what you mean by "full spectrum". The bulb is 6500 degrees Kelvin which classifies it as "overcast daylight". It is a very bright white light though some color charts say that it is a "bluish" white. It does din over time but I did not really notice it until I replaced it with a new bulb. I have 5 lights with these bulbs which are used as desk or reading lights. The older I get the more light I need. I hope that helps.

If you are referring to the blue spectrum emitted by the light, the answer is yes.

That information is not available on the packaging and the bulbs. To me it looks like they have about the same output as the conventional bulbs.

I'm not sure, as these are the only ones we've tried so far. We have two fixtures with these bulbs in our kitchen and we like them so much better than the fluorescent lights we had before. Seems pretty bright to us.

Yes. They have 5 bulbs in each fixture that can each be turned on/off to give you exactly the amount of light you need. I love mine.
