With ambient temp 25C got 45C on heatsink

Sorry for so long long absence. For my excuse i was prepare to cannaFest in czech. Hire is my crew. meanwhile i finish new product 400W Blast and 800W explosion. and we move lab to new buildings.. so now i have to make more measurement and in 1 week ill upload this files hire... new...

because newest ssl80 have more power output and ill use not 4 cobs but 6 cobs so i decide use 4pcs 730nm bin 3s-4s and 8pcs 660nm bin 3t-4t for every cob led. Another nice feature will be power reduction and switch red boost quite important in early phase vegetation

For last few days i spend figure out how send any samples of my explosion light to US. And main problem was size and wight. So i start prototype new chasiss base on only 36cm long heatsink. To make it use some special thermal paste that we develop with my best friend on local...

For CLU058 lens should be at last 80mm size. If it smaller you will lost lots of light. Even my 78mm lens not working perfect on 38mm cobs... Its compromise Size/weigh vs efficient/economy. I working on new supplementation MCPCB base on CLU048 when i finish ill make test and compere...

4pcs it's no problem send me pm ;)

so What's wrong is with say true about light and share knowledge? Or hire is somebody who try stop the progress, and trying to tell every body that earth is flat and only he knows everything ...

sorry to spam hire. But Fuck no, were is my tread :( What's now ? i didn't make any adverts !! fucker....

just remember one main rule 3 worst bin leds always is better than 2 in top bin class. for example lets take 2 COB clu058 1825 run at 2000mA aprox. 200W and 3 clu 048 run at 1.350 mA same power give you 3-4% more optical radiation. same with cost of cobs two of 1825 cost more than...

look at the size :) i use one project sun simulator 1.2m size Fresnel lens. It give me huge very uniformity beam almost parallel light.. But size.. we need some compact lens..

but they have own product.. any way Khatod make good quality silicone lens..

not huge lost but yes its waste a light but the hexagon was already there i replace the long fluorescent source of light by my RGBW panels and puts 2 defuse film. No its not possible, in supplemented board( too many source of light under on lens. ). Borosilicate glass is optimal way to...

Yes I make CAD model those lens with using LTI Optics | Photopia Optical Design Software. ans make many prototype in optical silicone before i made final version. Of course we can make better more clear version with using silcone but it will be 3-4 time higher price than glass Or we can...

@Hybridway I pretty sure that my new cob light which i working on now, you will test on yours plants. and we will compere to Citi horti cob and HPS. Because at now I'm curries about who is the winner : Citizen horti COBs HPS bulbs or my light base on citizen 3000K Ra90 plus...

Friends do not be angry for someone is not able to keep. I have come here to share knowledge, and because we share one passion. For me this light. This makes it with my knowledge educated at the university becomes useful. I'm not going to settle for the show a few products or the presentation...

Wrong, its not about 8 or 2 or one point of light but problem is that COB have gaussian light distribution like this most of light is in the center and trust my i can make test with your grid and my result will be same 80-85% uniformity for all surface but in correct...

not 15% total amount of all light :) but this is ratio for UV Tube. Tube is 20W and spectrum is from 180nm to 500nm but most importand is 15% 180-280nm ( UVC) and 33% 289-315 (uvb)

Yes i read this, I not biology men but from my research when you put UV light it the end flowering its make : First UV C is biocidal effect so its start slowly killing your plant and protect your crop from insect fungus and any mold. But most important is plant reaction for that...

@Hybridway Wow you have tested lamp SolarECLIPSE™ 350+UVB, Its funny and real story about 6-7 month ago ive been in china and i saw that product in UV tube factory. A i said that nice combination source of light but in low quality components in driver Power factror less than 90...

@Malocan im not said that he sell citizen cobs (maybe in past) but definitely he sell lens for many cobs like cree and citi... You will be happy because im during the test with explosion in box so on the weekend ill send you footprint without lens in 60cm and 90cm lens usually take 4-5%
