    Can cobs be used as side lighting

    all guessing on this for me...but in that case I'd just use the same power you use on top than. Kinda depends on beam angles and stuff. area 51 seems to hit a wide angle at 70w or something..don't know the exact specs. The tasty leds have a lens so probably tighter beam..bit farther away setup...

    Can cobs be used as side lighting

    @MrMoores there was a good sized grow doing that with pics and he did really well. Don't recall the user name...was early on when cobs first came out. Someone else doing it now with the area 51 cobs..greensantas grow? I'd do it if my space allowed...probably aim for a high efficiency cob and...

    The far red thread

    @tick tack toe Looks like 350ma..should be fine on the L shape if that gives you the best spot to hit everything evenly. I had 10w ledengin at 700ma on a long and thin strip and they are still going till this day. 3w is a better choice though, 10w is just what I had at the time. Just 3 of...

    DIY : Making your own Metal Core Printed Circuit Boards for led applications .

    thanks for clearing that up growmau. I'd be interested in those for sure, right up my alley. I try to be somewhat careful promoting reds. There isn't a night and day difference. I do it from the perspective that they are just extra tools to use in growing and while it may be deep reds today...

    DIY : Making your own Metal Core Printed Circuit Boards for led applications .

    Nice.. No lens for me though Kinda wondering...say we can order the pcb from someone that stocks them. Applying the solder paste to multiple tiny oslon or even cree reds would be really challenging without a matching stencil. Being right next to each other you couldnt really do one at a...

    Now what in the world would give you that idea...:finger:. Sliding coolers and cheap aluminum boxes..:hump: Lol...just kidding. I knew there was a reason i never popped the hood on the later versions. Its like when they made lambos on a fiero chassis. All good until you start the engine or look...

    DIY led grow

    Really don't know, don't keep a calendar or anything. At least a month from clone. Gsc is my toughest plant to clone, always slow and small roots out of the cloner. Surprised she grew out of her bad start 1g smart pot. Never used 6k... Probably similar I'd guess. Maybe tighter nodes.... I'm...

    Best LED's?

    I've never hated mars franjan.... They have pissed me off in the past with 2 bad lights in a row. But...if they can offer a well designed cree model at a affordable price then whats to hate? They do have some of the lowest priced lights around that would make fun grow lights for less serious...

    Anyone using COB/Cree LEDs in micro?

    Yep...the dimmer will put the light level where it needs to be if the light has more photons than the space can take. Using more of the leds capacity is a good idea usually. Less cost for more available light. Up to a point...before your making a high powered flashlight/highbay and not a...

    IF you are new to LED and want help choosing what to buy, POST HERE!

    wow..thats a lot of stars. Did about 80 once, takes some time but not too bad. Little confusing how you wrote that up but I'll give it a try. So the driver 36-60v...You need at least 36v and no more than 60v basically. Assuming the drivers specs are accurate. You need to look at the place you...

    Boxes or Some Type of Enclosure for DIY lights?

    The lid comes separate off of amazon. You could get a perforated sheet instead, cut it with metal shears, and screw it in. Holes may not line up, might have to make new holes. or just leave the lid off.. So easy to add a fan when using a box its hard not to
