Question on nm is the wavelength range 400 - 700 nanometers (nm) of the Red &amp; Green lights. Because looking for specific wavelengths.

This light has those nm so it will help plants to grow. But it ready doesn't have enough wattage to cover enough area to feed the plant properly. I went up to a 7 watt bulb but it was still too low in wattage. You need at least 15 watts to get the proper color balance and cover most of the plant. like in my case grass seed for my cats in a planter. If you have several or a large plant you may need two 15 watt bulbs. Gives the whole plant better coverage.

each color specific spectrum range uses a different current. I use a variable pot to determine the fixed value of resistor I need. also give you a chance to determine the brightness of the led for your needs. from a dim light to a very bright light can be hundred + ohms difference.. experiment with a variable pot 5k for best results. if need you can use a smaller pot. ps not all specific spectrum range have the same forward voltage. red uses the less if i remember correct... play.... experiment = learn .."tell me i wont remember .. show me i will know how to do it again.. let me do it i wont forget.....

I don't know if it's exactly 850 nm. If you look directly at the light (LEDs) at night, you can see that the lights are red (not blue). It does not add any light to the surrounding area, but the light itself can be seen from quite a distance (although very dim, I can see it from 20-30 feet away) if you look right at it. However, it does not shine any visible light into my daughter's bedroom, which was my main concern. My security camera (Archerfish Solo, now called CheckVideo Solo, is non-IR) is now able to see everything at night with the use of this light.

Stan, Sorry I don't have the quantitative data available such that I refer you to the manufacturer for it. Qualitatively, however, mine is doing a good job. Uncharacteristically we had a week of clouds and rain lately. As a result, the brightness and duration was impaired somewhat but at 0530 hours of the morning of the fifth day there was still a glow emitting from the 20-or-so LEDs. Now that we're past the autumnal equinox I expect some diminishment but we're more than likely to have clear than obscured skies at my altitude (~6700 ft) and latitude (~ 41degrees N) during the upcoming winter period.

The light that these bulbs produce is the closest spectrum to natural sunlight. I purchased several of these for my mom and my girlfriend and they love them. It is much easier on your eyes than the "yellowish" fluorescent lighting that most bulbs produce and is great for reading and crafts also. I hope this was helpful. Dave J.

450nm is not UV, that is visible blue color. UV (ultraviolet) is less than 400nm in wavelength. Fluke makes a really good UV light that emits 395nm. But it costs over $50.

This illuminator works in the 850 nm range which is visible in the near-infared range. They work with cameras that are built to use the 850 nm range (filter). The other range, which emits a less visible purplish glow, is the 920nm. The camera MUST match the illuminator and visa/versa. If you try to use the lesser visible 920nm illuminator with a camera which is designed to work with 850nm they just don't work together and the same goes with a camera that is designed with a 920nm filter and you try to use the 850nm illuminators. You get a little but you'll be disappointed. Make sure your camera and your illuminator wavelength match and you'll be happy.

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 went to streamlight's web site and peak output for IR LED is 880nm at peak or high setting. You can probably quater that for each of the settings from dimmist to brightest. Go to their website for a spec sheet, hope this helps...

Sorry for responding late, but I did not have the lamp at immediate reach. Now, I verified it, and you are right. Mine is not working, either. I refer to center LED labeled #58, with the tag 730, which does not turn at all when all the rest do. Somebody could say that 730 (nm, I suppose) is beyond the range of human visión, but I guess that at least a dim red light glow should be emitted. Regards. Alvaro.

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

Check the specs or the camera--wavelength against wavelengths emitted by light.

Hello,The CMVision also provides infrared light in the 850 nm range. While I was using the device, it easily illuminated to 50 feet and beyond. Unfortunately, I had to return it since the LED's stopped working. The device definitely has the 50 feet range though.Good luck

Yes, the IR LEDs emit a visible red glow in the 890 nanometer wavelength.it is a very good illuminator for the price. I have also purchased Invisible IR-200-940 CMVision 940nm Wavelength 198 IRLED.Look for 940nm IR LEDs. If u want invisable. But be careful. Alot of cameras will not detect light at that high of a wavelength.

254 nm which is well within the germicidal range -this is the peak emission frequency of the Phillips bulb used in the systemLook up UVC in Wikipedia then check the bulb specs in the Phillips site
