  1. Almost bought one of these. I was debating between this and The hlg growers choice roi. but then I decided to splurge and get what I considered to be the top model on the market the optic 600 slim h. Seeing that this model and the Arden are the only two with the new top of the line 301 h Samsung chips in it, that I know of, I figured had to go with the top efficacy. I thought about waiting for your 2019 best of review show but I could not wait. hopefully this YouTube channel has educated me sufficiently to have purchased the best light for me. I think it has and I thank you for your help.

  2. Hi, to calculate the PPFD/W I should take 1.5×1.5=2.25 then 2.25×747= 1680.75 and last 1680.75/800= 2.1. It should be 2.12 according to the video, what am I getting wrong?

  3. Awesome video big fan of your channel very educational but I’m curious why you never made a review on the mars Hydro TS600 very powerful little light I don’t see no content in your channel

  4. The main problem with this type of 'bar' light is that they simply don't have the ability to penetrate the mid and lower parts of the plant canopy like the 'lense' style lights can. I would be curious to see what kind of penetration this light has compared to the Migro?…. My bet is on the Migro.

  5. First Thank you again for your work. I would ask is it possible to sometimes take a light like this and dim it down to 80/60 percent and test it in say a 4×4 and see what numbers you get. As sometimes you might run a light like that which is too much power for a 4×4 however dimmed down the efficiency goes up. Thanks

  6. I have a suggestion for a light to test it's made by maxsisun it's called the pb-2000 it's a 200 watt quantum board light with a driver that is dimmable extremely nice quality budget light I hope to see you test it sometime thank you

  7. How about testing new LEDs from Lumatek? They're from the UK. Zeus series: Zeus Pro 600W (1620 umol) or 1000W (2700 umol). They're 6-10 strip LEDs, top bin Osram diodes (full spectrum probably 4K, extra 660 and it looks like they even have some 730). They run at lower current (3600 diodes per fixture!), 2.7 umol/J and great design – you can easily unplug (no cables) individual bars and customize your output/coverage.

  8. Интересно, это здесь Горшкоф спиздил идею своего Прометея? (Не пытайтесь переводить, это для русских).

  9. I really think this style of fitting is future for indoor growing very even spread of light across the whole canopy. I think something like this will be my next DIY build if I can source suitable stuff.
