I think 40w is great if you have extra height. Even the best bar lights are weak in the corners, and a higher light makes a more uniform canopy. I need at least 35w/ft.Yeah id say that fits the bill pretty well. Seeing these recommendations for 40w per sq ft. Makes me cringe
Yeah i should add that its ppfd that matters. Light style also plays a role as the further you keep then the higher the wattage you need to run.I think 40w is great if you have extra height.

You should b able to brother ..how highs your ceiling..i keep the lumatek pro 600 between 20-24" at 625 watt..some grows i will get one closer and get a little fox tailing..im running the se 7000 now between 20--24 ' at 85% which is 620 watts and tops are very uniform..Currently I have 600w of led in a 5x5, I can’t even use all 600
Lol
I've been running an ROI-E720 in a 5 x 5 and have no issues running the light at 100% (800 watts) @ 18".You should b able to brother ..how highs your ceiling..i keep the lumatek pro 600 between 20-24" at 625 watt..some grows i will get one closer and get a little fox tailing..im running the se 7000 now between 20--24 ' at 85% which is 620 watts and tops are very uniform..
Good choice. In many situations, 2 smaller lights will provide better coverage than 1 large light. Total wattage being equal in both cases.Dispersion of the light, I think, may also be worth considering. I started thinking about this while thinking about how the sun provides light at different angles throughout the day. We don't move our lights to mimic that, but we can spread the light by using a wider span of lights. That, in addition to watts per area was the reasoning behind why I decided to use two light panels.

One thing I have not seen mentioned is if you're growing in a tent with reflective mylar walls, you can get away with a bit less wattage because the light off the tent walls is reflected back into the grow space.

Shane is good, but so is Dr Bugbee. Personally I like them both.Shane is the sheet and thanks for the thread @Shaded_OneI have followed him since before my 1st grow and the dude is legit af. I love when the person is unquestionably matrix-like knowledgeable but also humble to boot and easy to understand
Shane probably reads the farm. We figured it out years ago. Lot of know it alls wanted to argue. lolShane is the sheet and thanks for the thread @Shaded_OneI have followed him since before my 1st grow and the dude is legit af.
