Anyone have a spectrum on this bulb? Thanks.

In my opinion - - expect around the 4200k area. Unless something has changed lately. I will also say that they still perform very well with the addition of Foliar feeding during Veg, (very nice), dark period will need to be increased. cheers

I could not find the 6400K full spectrum 27 watt bulb at Lowe's..or anywhere else in my town...or on Amazon. So I called the distributor of the lamp and they said I could order bulbs from them, which is what I did. The bulb was about $10 including shipping, as of mid-2014.

another reply to what I already answered. if you have a Home depot in your area they sell full spectrum bulbs of this type and can tell you what the replacement number to buy.

regular bulbs are not full spectrum unless its stated on the package. these are good though i ordered one a few months ago and with about 6-8 hours of use every day its still going.

Try a different bulb. You can try this LED, it worked for me. And its beautiful lighting is a big plus Triangle Bulbs T90020 (Pack of 2) G16 Decorative Globe Light Bulbs 300 Lumen 5-watt LED Light Bulb with E26 Base, Color 3000K, Dimmable, UL Listed, Energy star certified,

CRI = >80Reference this sheet for all specifications. http://www.feit.com/documents/pdf/PAR30L_5K_LEDG5_SpecSheet.pdf. I have a few dozen of these bulbs in a commercial setting and spec this on a regular basis. The color rendering index is quite high.

I noticed another brand allowed the bulb to be "re-clocked". I think I see that on mine, but in town I never get to go on high beam. I'll have to re-check the 3 tabs to see if I can rotate them up.

Most bi-pin 20w halogens that I have seen are MR11. So you're probably in good shape. It's frustrating that the owner's manual from their own website does not state what kind of bulb this is precisely.

Dear Harriette, i just can recomand this bulb, we are very pleased with it. It is not just bright enough, it is also saving a lot of energie. I am pretty sure that you will love it. It is work to try it out. Best regards Diana

Hi there - typical incandescent/halogen R20 (not PAR20) bulbs have a spread of 110-140 degrees, so you should expect similar with this bulb, maybe a bit narrower because it's LED. But it should very likely be a wide flood. I have not tested this specific model in my home.

I use just any old bulb I found laying around the house. 40 watt, 60 watt. Or even the new CFL's work!

I don't have a method for spectrum analysis, the light is pleasing and 'normal' to me. I'll say that it IS more "blue-ish" than "yellow-ish".

I'll try to answer this question even though the wording is odd. If you are asking where on the color spectrum they are, they are 6500K on the color temperature spectrum. This is similar to the color of daylight on an overcast day. Not really on the blue or orange side of the spectrum. Pretty close to white light. I can't find a wavelength chart that breaks down the distribution of wavelengths for these bulbs.

I'm afraid I can't answer either question, since I don't know exactly what spectrum is needed to treat SAD. Nor do I know the lumens of the bulb. I do know, though, that I find it startling to look over in that direction (where the plants are) at night, because it seems as if the sun was out. Sometimes if I'm working beside that bulb I lose track of time and have no idea that the evening is so advanced because the light, well, it seems like daylight. Good luck!

Mine arrived without bulbs included. The answer to that question depends on what spectrum bulbs you purchase.

Hi Scott. I don't know from experience yet, but I'm in the same boat as you. I live in Ohio & have this bulb in my unheated garage. I read at least one review somewhere that said low temperature is not a problem & basically I'm hoping that review was correct. Btw, I'm very happy with this bulb so far despite the high price. I considered putting in fluorescent lighting but don't need to now with how much light this puts out. Good luck! Jerry
