ok went ahead and ordered the 3w red/blue from steves with the driver. Im thinking of buying a 40 inch piece of the 8.46. This would give me enough cooling for 4 cxa/b COBs and some 3w and the ability to expand later by up to 2 CXBs and a few more 3w if I chose to down the road, for now its...

Where do you get the surface area figure from? if I cant go that short I will probably just do a smaller fan and heatsink of a longer length, maybe something around 36 inches for good light spread (over a 4 foot Length), but now I want to make sure my cooling will be there with the correct math.

Hey thanks Man! Im excited too! Ok trying to put together a build. Thinking of doing the 8.46 profile heatsink at a 20 inch length( short enough to fit the short way in the tent easily, and being just larger than a 200mm computer fan. Since I can get the CXB in 3000K I was thinking of doing 2 of...

Awesome thanks again for all the help and info, I really appreciate it. I think building them one or 2 at a time and eventually consolidating would be great for me. I also have a small 2X2 space for mother/clones so having flexibility with lights is a big plus. Currently running( first grow back...

Hey Hey thanks for the help and all the info, I have more reading to do! This may be just the way to do it. Currently growing 1 each g13 gigabud, g13 pineapple express 2, and dinafem blue Thai using FIM and LST. Also going to lollipop freebies that I just popped,delicious seeds sugar candy and...

OK so I think I'm gonna pull the trigger and start ordering parts but I do have yet a other question or two. 1. Since I can't seem to find any 4000K 3070 Cree anywhere ( I would like the light built in a month from now so can't wait for spec order really)should I just go 3000K for my first 4...

Hey how do you guys go about making your cases? Do you just do thin sheeting and use a press? Just wonderin?

ok great, thanks for all your help. Off to read more... :) Hey looking at your material list are you thinking of everything just riding on the heatsink with a fan blowing over the driver, or expecting me to come up with a tube design to house the driver ( which i can certainly do). Just wasn't...

great man, thanks for all the help. I do have a couple more questions tho. Firstly is there another place to order 3070 cxb 4000k by single LED? Mouser seems to carry the 3000k only in single stock, 4000k are special order 100 count, there is also a 3500k single order but 6 week lead time...

ok cool could you help me out? I have been reading on this stuff but I am still pretty boggled. I am in a 2x4x5t space. what lights and drivers should i use, there are so many variations on everything I am afraid to get the wrong thing and blow out my LEDs or something....I cant find the exact...

Hey now that you have had this light a while im looking at the post where you are scaling the light to just 4 cree per driver, no mention of the other colored COBs. Is this because you just used crees as an example or you just no longer find merit in the colored cobs instead of just adding more...

also how far away from the plant do these crees need to be? I only have a 60 inch tent

yeah I have looked at this guide. Would you say I can build this exact light in dimensions that fit my space or is that too much. 285 watts of actual high par lighting seems perfect for my space but his space looks bigger with that light. Is this going to be overkill for me?

I currently just upgraded my tent to a 2ftx4ftx5tall tent. I have a collection of small/cheap LED lights. One from previous grows about 2-3 years ago and a couple different newer ones I bought trying stuff out. Illuminator 100watt (85 actual draw), a galaxy hydro 180w (pulls like 90 actual), and...

one is an old 90w illuminator ufo (which is much weaker than the other 2, you can see the diodes in the camera where you just see spotlight from the other 2). The other lights are a kessil 350m and a galaxyhydro 180w. I might buy another galaxy 180 for this grow in about a month and move the...

Got my new tent set up today, now in a 4x2x5t. I also am now running a 6 in fan and filter ( it already needs it). I will be cutting down my old tent to fit next to this one in my limited space to use as a cloner/mother tent. fed fox farms grow big last water and they loved it, I also just FIM'd...

Ok perfect. I was kicking around just buying a 4 inch filter but that was over half of the six inch combo with a controller so I just went for that. I will be gone working till the weekend so I was thinking about topping again on the gigabud and/or pineapple (maybe FIM) once I get back, then...

ok just bought a bigger tent lol. got a 4ftx2f so il run that as my flower chamber and my current 2x2 as a mother/cloner. also bought a 6 inch duct fan and filter combo to vent both tents with. still have a 4 inch fan as a spare. Im going to post some pictures , and I could also use some advice...

Nice my 350 has added some faster growth to my setup, can't wait to flower the cause it's a magenta 350. Can't wait to see your pics!

hows it coming dude, i ended up picking up a new 350 magenta for 175 but I am curious to see how your 380 grow is going?
