Great UV-C bulb
I use these to deal with Covid and mold. The only purpose of the outer glass bulb is to filter out the dangerous UV-C rays. So, if you take off the otter glass bulb you will be left with the small quartz bulb which you can turn on with the appropriate ballast. The UV-C light and Ozone given off by the bulb will easily sterilize all surfaces exposed to the light in a 20 x 20 room. It will kill everything, from viruses and mold to any plants in the room. PLEASE. PLEASE DO NOT EXPOSE YOURSELF AND YOUR EYES TO THE LIGHT EMMITTED BY THE INNER BULB.

Not all the same brightness.
Ordered one pack of four. When they arrived, one had loose glass inside and when tested did not function. Installed the other three and two of them we not as bright as the third one installed as can be seen from the attached photo - the furthest one is obviously the brightest. I have requested a return and refund on the fourth non-functioning lamp - hopefully they will honor a 25% refund of the total 4 pack price.

Good Greenhouse Bulbs
They work well and last for quite a long time. We received a package of 4. 2 arrived broken. The seller refunded the cost of the two broken bulbs. Excellent seller.
