do the SunSun Lighting A19 LED Light Bulb, 6.5W (40W), 450lm Cool White, (5000K) put out any UV Radiation?

To the best of my knowledge.....no. UV would be visible as more of a blue/violet light to the naked eye and these bulbs put out a very bright white light.

Led I don't know but it works with UV light...I don't know the difference between the two

It is a LED with a color temperature of 5000k and CRI if 80. How close that is to "sunlight" is subject to your own opionions, not to mention what kind of conditions you are measuring "sunlight" in (sunlight color temperatures vary with time of day, overcast or not, etc). Clearly no lightbulb gives off true sunlight, or anything all that close to it, despite marketing terms being used to describe bulbs that try to be closer than average. (Some of the differences are good, would you really want a lightbulb that gives you sunburn?)

It is never too hot to touch the metal desklamp shade I have above it. It gets very warm but not hot. I would say less than or about the same as a 40 watt bulb.

I don't know exact numbers on the UV protection but they definitely keep the sun out so I'm sure the UV protection is pretty strong.

No. LED lights and HID lights (HPS for example) emit a completely different UV spectrum. When flowering, HPS is fine by itself-as long as it is powerful enough.

Yes Ronald. It is definitely a 40 watt UV bulb. I buy mine at Lowes Hardware. And ya can also buy them at Walley World. Can't remember the price though. Hope this helps.

UV has a light wavelength below that of the visible range. Since these lights are all within the visible range (minus the red which has part of it in the IR), there should be no UV rays.

I doubt led can output UV for plants and I would say the spectrum is 4100 K.

It has worked well with Ecosmart A19 2700K LED Bulb 6 Watt, 40 Watt Equivalent Omni-Directional, Dimmable, Soft White (2-pack) for about 9 months now. I can't say if it impacts the overall life of the LEDs though.

I use a uv lamp and it works perfect. My aunt says you can use with led lamp. But I'd stick to the uv. I know for certain it works.

I will be very honest with you, this unit I got, the UV light shorted out or burned out. But they replaced the whole unit for me. However, I did not get the same one with the UV in it. So I have never replaced the bulb! I had no problems with the company & recieving my replacement filter. I don't know if this helped you or not.

It has a uv bulb you have to change every 250 days or so. It's stated in the instructions provided.

These are pretty large bulbs that I use in 1900's photographic processes because they are fairly rich in light at the blue end of the spectrum. They do NOT produce much UV wavelengths (380 nm and below). I believe grow lights include UV output. Natural daylight (which plants like) is rich in UV. As for a general room light, the cast is pretty industrial, not warm and inviting. They work great for my application.

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.

About 100 watts with the UV, maybe 75 watts with no UV. (just an estimate, not exactly sure)
