Trashedagain77 Posted April 3, 2023 Share Posted April 3, 2023 Hi all, I'm close to buying some LEDs and wanted the experts opinions on which is better a quantum board or strip configuration (same power i.e 300w). Thanks in advance. Peace. 2 Link to comment Share on other sites More sharing options...
Clubs Posted April 3, 2023 Share Posted April 3, 2023 Strips I'd say, better light spread really. The Lumantek ATS Pro 300W looks to have a clever configuration so I'd be looking at something like that personally. Not too bad price-wise either. 5 Link to comment Share on other sites More sharing options...

Thanks in advance. Peace. I swapped to LED a few years ago. I bought a couple of daisy chained quantum boards (200W) & recently added a two bar strip lamp (125W). In my opinion I'd buy quality. What LED chips, how many chips & what driver is running it? Obviously finances come into it. How much can I afford to spend and running costs? A 600W LED uses the same electricity as a 600W HPS (or it should or someone is telling porkys!). Look for expandable systems, both decent strips and quantum boards support this. 300W of LED should cope with a 1m square area easily. 5 Link to comment Share on other sites More sharing options...
Goodbloke Posted April 3, 2023 Share Posted April 3, 2023 I'd go with bars, they have advantages over the boards, there's a recent thread on this. Easier to get what waste heat the fixture does create down to the canopy with a fan above, useful in the colder months. Yo-Yos can be strung easier. The bars position can be adjusted to suit requirements on some fixtures. Lighter possibly? 1 Link to comment Share on other sites More sharing options...
Arthur Mix Posted April 3, 2023 Share Posted April 3, 2023 I prefer boards over strips I’ve run both and just boards are better for my space than strips 5 Link to comment Share on other sites More sharing options...
Military Grade Posted April 4, 2023 Share Posted April 4, 2023 I have a board and plan to upgrade to a Lumatek ATS Pro 200w for a 60x60 tent. I definitely don't regret buying the board as I can use it for mothers or clones one day. At the time of my purchase my old light died mid grow and I had to buy a light ASAP, so I got the best 100w light for the money at the time. If I wasn't forced into buying one so suddenly I would have definitely saved up a bit more and got a light with better spread with bars/strips. 3 Link to comment Share on other sites More sharing options...
catweazle1 Posted April 4, 2023 Share Posted April 4, 2023 Lights from strips allow you to blow air downwards onto tthe canopy to reuse some of the heat. The square-shaped Lumatek ATS 200w and 300w allow it as well. 4 Link to comment Share on other sites More sharing options...
KC Posted April 4, 2023 Share Posted April 4, 2023 As long as it lights your space properly I doubt it matters really. I swopped 1kw of hid for 630w of led on a board and it smashes it, strips would have probably done the same. Benefits of the board are they leave more room at the top of the tent for your extraction setup and they also act like a little panel heater to keep your canopy warm. 2 Link to comment Share on other sites More sharing options...

LEDs can and do outplay HID bulbs. IMHO my 325W (at the socket) setup is close to a 600W HPS and will last a lot longer. What annoys me is the naming policy some brands of LED lights observe. 'The 1000W <<Itsert name here>>' that actually draws 200W from the socket. Some of the lights (not all) are perfectly serviceable, so why the misleading marketing? The first LED I used claimed to be a 1000W light. It actually drew 120W. It was a 'blurple' with a noisy fan. It grew a half decent crop but compared to a modern decent LED it wasn't comparable (Honda Melody < Honda CBR sort of shit!). I think things are generally improving regarding this aspect of advertising along with the buyers awareness. 4 Link to comment Share on other sites More sharing options...

Hid 600 watt pulls 660 watt from socket so even more savings.peace Goohfy. 2 Link to comment Share on other sites More sharing options...

If is has decent chips & a decent driver (ballast) & it pulls the wattage it claims you are probably on to a winner. 2 Link to comment Share on other sites More sharing options...
Thai Stick Posted April 6, 2023 Share Posted April 6, 2023 Either or to be honest. As long as it uses Samsung LM301H diodes as the main leds and something like osram (avoid epistar) for far red and blue spectrum then you are good. I use boards and strips. I have achieved both amazing results of 2-2.5 grams per watt with boards and 0.5 grams per watt with the strips. That has happened the other way around too. Just have to dial in the environment and brightness levels vs distance from canopy with the strain your growing and you will do well. 2 Link to comment Share on other sites More sharing options...
