The light bulb I got is a10,000K Daylight and True Actinic Blue Light bulb. I just want to make sure it isn't to powerful, for my plants and my tadpole, it seems to radiate some heat I got a 2 degree increase from 73°F to 75°F after running it for about 6 hours today, thanks. I have turned it off until I can find out whether it is safe please let me know, I can't find anything about it on the forum or elsewhere on the interweb.
