I know he's working on a FAR RED version and I think that as a product would be very useful as an add for people at a pretty low entry price cheers Mark

This is a solid 2x2 design with our new boost boards, even coverage, 2.9 umoles/j, 8 of these are 21 watts each will give you 900 PPFD av at 18 Inches Cheers

Sorry did you mean a single board, no I would suggest 2-3 boards will be required, so driver need would be based on that Cheers

So there are several things to consider and these is some confusion about specs, let me drop into point mode for a moment single die or single chip UVB/C are typically quite low in output, the best I know is the Nichia 280nm chip at 55mw, NCSU334A Radiant energy output (mwatt or watt)is not to...

I would think Migro is a bit out of his depth discussing the performance of UV diodes to be honest, nothing about his videos indicates he has an in depth knowledge of diode architecture or performance:confused:

Ok got it, I think I also mentioned currently we have not meter that can measure into sub 365nm, We expect to have some gear soon to test this Cheers

1200PPFD centres, near 1000 PPFD in the corners Cheers

You mean UVA or UVB/C? Cheers

This is a build with 48 strips at 40 watts per square foot, running strips at 30 watts each 2.8umoles/j Based on 6 inches to the canopy Cheers Mark

what what size area

Hi Grotbags, yes we will move to large leds on the centre channel 3535 ie Cree XPG-3, wider UV range, etc and make some other subtle changes, should be coming out in April, along with Boost Boards Cheers Mark

Its one of multiple lights, when stacked out the UVA are not actually on the edges, with the exception of the first and last cheers

Thanks Air, you might like this, delivered to a customer. New 224LPW Nichia HT, with G Bin XPG-3 G Bin Deep Red and and Mixed UVA all mounted to TSLOT Cheers Mark

Phosphor looks like 3k Cheers

The generation of COB you use wont impact the design, other than provide you with greater efficiency, more likely the extra 60 watt of light tipped you over to too much light in a non CO2 environment, maybe just adding CO2 is the simplest solution. However moving to a strip build will certainly...

Based on the image they appear to be Cree, however the only odd thing is the solder pads show a streak of solder coming out the centre of each led, but that may only be the underlying solder relief pad design. Without eyeballing it face to face I would say based on what I can see 90% chance its...

looks more like 3030 but hard to tell as the lens makes them look bigger

Good to see you back bro, its been too long, RIU should have a pioneer avatar label, you qualify Cheers Mark

Customer built a 4x2 Tent wanting total control of spectrum, so used illumi bluetooth mesh good ppfd numbers cheers

I had a bunch running in a tub of water for 4 hours, no issue.
