I'll start off on the right foot here and not think your spamming since your new here, maybe you post on other forums idk...but do you have pics to back up these claims with these lights by any chance? I'm not one to be cheap as Ive bought/spent a shit ton of equipment over the years but have threads backing it all up whether good or bad purchases.
And that is the million dollar problem folks. Some work most don't work as good as they claim. So that leads us to this discussion which is a shit show but we can end it now that we know the facts.
Area 51 - Great lights, known bin numbers, always a thoroughly tested product.
Hans Panels - Workin strong
Advancedledlights - Bin numbers unknown, many people point towards Area 51 as a more cost efficient and know what you pay for light. (but it works)
Blackdog - Chinese rebrander
Kind - Because being kind to your wallet is uncapitalistic
Lush - You can trust us cuz we go to every event and claim all kinds of shit. (subcool still uses his lush light guys!!!! oh yeah its on the side of his grow LMFAO)
The chinese ebay lights - Because YOU can grow too! for about 2 months before we fail. If we don't fail though you might not enjoy the resin and flower development that you could with a better light.
Every light you buy in LEDs is a stepping stone, even if you buy the most expensive most thought out scientific pos. There will be better the next year and the next year after that. That leads us to conclude that anyone buying a cheap ass light and having it work for a year is a good strategy if they can make it produce. Save that money and get a beaster next year kiddies!
