    How many watts and lumens is a good target for a 4x4

    I'm only a beginner myself mate, but it just doesn't make sense that the ppfd goes up infinitely based on the number of strips. I think power has to factor into the equation then see what you get out. Pretty sure that's the bit missing from the calculation.

    How many watts and lumens is a good target for a 4x4

    You must be. I think you have to take into account the max current the driver can put out because otherwise you'd have a potentially infinite ppfd based on the number of strips the user chooses to use based on your equation surely?

    So if I want the driver mounted away from the light itself, does that limit me to a certain type of driver or can I do that with them all? Thanks

    I know you've mentioned that to me before and it makes sense. Comes in handy as a starter light then as well. Do bear in mind that I'm used to having 3 x 1m secret jardin parabolic hoods hanging in there though brother, and believe me, moving them out of the way is a major pain in the ass. My...

    Alright then... so I want to put my drivers on the same order as my strips on Digikey. So.... which ones should I go for? Power per fixture will be 480w max. More likely driven at about 420w, but based on the post above from @Rocket Soul maybe even needing dimming a bit more.

    hello mate. I've worked out 40w as 900w over the two fixtures. If I go full power at 960w I've got 42w/sf Now I hear what you're saying about getting greedy, but... that little 1m space might be my fail-safe there because those numbers have got me thinking ( in a greedy way) If I dial it...

    I've decided to keep things basic with the first four lights. It'll be 2 x BXEB 3000k fixtures 2 x F-Series fixtures 2 x Cutter PR boost fixtures What'll be interesting to me is seeing how the first two builds, basic strips with no added deep or far red, compare with the PR boosts, which...

    Ok so after doing the due diligence, unless anyone suggests otherwise, I think a good basic option for me would be the F-Series. With 288 diodes per strip I think I'm good knocking a light or two together with those. 10 strips run at half power should give me near the max efficiency from them...

    Okay so stage 1. The lights. I've got the BXEB in the bag. Leaves me the 2 x LM301b and the 2 Cutter sets. Leaving the cutters apart for now. I'll start with the exact numbers for my space. 2 lights will actually cover an area 6.5 ft x 3.5 ft. Which means 900W - two of them on 450 - will...

    Okay, got a bit more time off work now and I want to use this next couple of days to make my final decision and get everything bought. I need to: 1. Make my final decision on lights and get them. - So far I've got the 90CRI BXEB from future elec. I'm just going to run these 50/50 with some...

    Ok next thing after the driver is the heatsink. What thickness and grade of aluminium is recommended for a grow light of this spec? Cheers

    Guide me to the Light....

    Thanks man. Yea I'm not gonna mess with the spectrum of these. I wanna see how they do on their own. When you say 2 on a sink, do you mean side by side and not end to end? If I run 40 with 480w I'm at 12w a strip. What driver would you recommend?

    Guide me to the Light....

    Ditched that idea. Gonna use the 40 strips on their own. And yes, they're 90CRI 3000K I think the 3000K will be a decent all rounder. Let' see.

    Yea I've just been chatting to Mark then. Still set on getting the Cutter kits. Just wanted to get something to run in my other space to see how they all stack up. I'll probably be migrating a lot of what I build around the place to use for other stuff eventually. I do a lot of fruit and veg and...

    Ok so... I just spent the first of my pennies... Ideally would have liked to chat with Mark over at cutter but I haven't heard back and there's nobody on the site. He's probably busy. So what I've decided to do is spread my bets a bit. I've just picked up 40 of these 90 CRI strips...
