What part of the spectrum does this light produce? I don't see the Nm in the product descriiption. Thanks.

Other websites show this as a 390nm wavelength but the ultra fire website doesn't show this model.

The lamp is not "full spectrum" as that would include the UV light, which with this unit is 99.3% filtered. The color temperature, lux level reaching the eye and the positioning of the lamp above the view plane are the more critical components based on expert guidelines. Before considering any bright light therapy product, consult with your physicain to ensure it is appropriate for your individual needs.

I don't know the output in lumens, but for my model the color is daylight or cool white, not warm white like and incandescent. Possibly you can specify a color temperature?

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 have checked the box, the instructions and the manufacturer's stamps on the product and I can't find any indication of the lumens/wattage. The light is a 5" LED strip and not one bulb, for example, the type used for nightlights. I was going to add a photo of the light to the product's original description but this is not an option.

As it says in the picture, it produces light between 365nm and 370nm. I can verify that it will fluoresce bodily fluids like urine, spit, etc.

I realize this is rather too late but it may help others... The light given off by the GoLite is in the 440-480nm range. Its peak output, that it to say the brightest wavelength, is at 464nm. White light also contains these wavelengths, but along with other colors which aren't necessary for melatonin suppression. This is how the GoLite can be less bright overall (in terms of a lux measurement) than other sad lights.

254 nm (nanometers) is in the ultraviolet part of the spectrum. Exposure to it will kill bacteria and viruses; it will damage one's eyes.

The meter measures the amount of light. To the best of my knowledge the light spectrum is not taken into account. I grow orchids in natural day light so I am not an authority on the best way to go with artificial lighting.

Hello w6zrd, we actually ordered the 940nm in error and returned it before ever using it. We have the 850nm lights and I do not see a red glow. So, I cannot comment on the 940nm lights.

Are you asking for the Kelvin color or for the Lumens? Neither is listed on the package, but the light is warm white is probably around 4000K (not too warm). The lumens are low and equivalent to a 40W bulb.

It is supposed to be a full spectrum light including a little UV. No need for grow/veg settings, but you can buy another one with more blue if you really think you need it for veg (like the http://www.amazon.com/Lighthouse-Hydro-Clone-Light-90-watt/dp/B00E8DVMJ8/ref=pd_sbs_lg_53 ).

The bulb is a broad spectrum 15 Watt T5, that gives a "violet" colored light. There is no K scale rating on the light or packaging.

Mine never worked well. Used it once and threw it away. It's very cheaply made, but the light nm is not mentioned anywhere.

at http://genet.gelighting.com/LightProducts/Dispatcher?REQUEST=COMMERCIALSPECPAGE&PR;ODUCTCODE=21739 , it shows that it's 2700K, which is a yellowish color. Mine only worked for a short time, and I remembered it as being more white, but I guess not.

My manual states it has up to 2,500 LUX of bright Natural Spectrum light so I always assumed it was full spectrum, but to further answer this question, you might want to contact the company, at verilux.com and ask them. I know I've been using it for almost a year and it has done wonders for me.

I've had the TT-AL09 120w for over a year now that has just the blues and whites. I agree with GCO and definitely look at a full spectrum fixture if you will have light hungry corals. I hope TaoTronics considers building a full spectrum light again.
