Chasing The Present
I have been following UVB info and have used Reptisun T5 in a small grow. I don't have room for a side by side so I am not making any claims but it makes sense that it adds in my mind. After all the info I could glean it seemed that the best UVB bulbs only reached 5-10 inches or so and watching you tube vids testing seemed to bear that out. Yet you say 3 FEET??! Wow. If that's verifiable that's impressive.
Initial treatment with these for skin disorders (psoriasis for example) is 90 seconds at 18", at 18" the UVI is 30+, the meter i used is 100% accurate to outdoor readings both on gauges I have tested and local known weather UV index readings...
The cool thing is u can buy them as they are also used in industry so not restricted ... buy a couple, stand 20" from it for 5 mins, you'll see... I've only ever run them 3 hours daily from at least 3' away, they work and anyone who's ever used medical UVB for skin issues know how strong these things are...
The power veg at like 8-10" are UVI per my meter a 5, the ushio mid range reads 100+ that close... I know, UVI reading that high are nuts but if it's an 8 outside it reads 8, it reads exactly as it should and these mid range up close burn skin in under 30 seconds, they are a serious bulb
I use them in winter personally too for vitamin D and my psoriasis
