on their site in the feede chart they say flush for the last week, but i couldnt find more

sorry to bring you the bummer but for example UVB and LED doesnt work good at the moment. In terms of costs, intensity and efficiency they will need some more years to get to the point where T5's are at the moment, just because T5's are used in large scale medical UVB-treatments. To build a...

he refers to a quote. dont take it seriously

Yes your are right, this is my own opinion that these T5's will do the UV-task, but you have to be very carefull. ( i mentioned this im my UV thread ) If you just wanna have a buld that does the job and contains some UV then it is perfect to go with the recommendsation of phillips. I just came...

I just wanna say again i just relate to pure UV output. Narrow Band UV only: Philips UV-B Narrowband TL 40W/01 RS (40W) [70 bucks] https://uk.proflamps.com/datasheets/fp-928011300101_pss_en_aa_001.pdf Broad Band UV only: Philips UVB Broadband TL 40W/12 RS SLV/25 (40W) [80 bucks]...

I know but the intensity of that UV spectrum isnt that high compared to a pure uv t5. ( i am not talking about the agromax pure uv ) I just wanted to say that no other type than a T5 is able of producing high intensity UV-A/B spectrum at a cost effective way and without overkill. Thats all :)

and also narrow spectrum and low intensity on further distance ( lower than t5's ) because they dont need to.

well just try to find something better, thats all proof u need, if u dont want to search for urself just take a look in my uv science clickbait, i checked all available sources ( types ). [ mostly UVB ]

at the moment there is no better affordable source for an UV-A/B spectrum available than a T5. no LED, no COB, not in a broad spectrum, not even in a narrow spectrum and not in that intensity.

well as long as the right amount of PPFD at a certain wavelength ( depending on stage of the plant ) hits the plants it doesnt matter which light source you use. you could even create your own sun, burn your grandma or fire a rocket. But in terms of efficiency there might be more efficience...

sadly they are some cheap noname monos well my friend finished his run but then his damn wife turned crazy, drinking alcohol again. They will quit the relationship and everybody has to search a new place to life, but as soon as he got his new place we gonna hang the light there... since it is...

the "hardest" UV-radiation tube for tanning i found had 2,5% UVB for a 6 feet 100W tube. Tanning tubes are made for small distances and therefore they cant have such a high output of UVB-radiation than a UV-tube which has been made for growing and big coverage. You would need to use a lot of...

i also found this tube while doing my searches. since it is a mixed spectrum tube ( UV + another spectrum ) i didnt go into it because i just wanted to write about light sources that emit UV-spectrum only ( or close to only UV ). For me the spectrum looks like a UVB tube with a peak at 311nm...

Yeah i will! also if u read the "calculation" part u know i wont go closer than 50cm ( about 20 inch ). This tube was alrdy !VERY DANGEROUS! in my calculations so in RL i wont fool around with this one!

For some testing reasons i ordered a "AgroMax pure uv T5" tube and it arrived today. Gonna take some pics and upload them.

3W monos mounted on an aluminiumstar each with a 90 degree lens.

ask him if the driver is constant current or not.
