Thanks,

I'm a firm believer that deep/hyper red is the way to go to ufrther improve our cob builds ...

I'm surprised 4T are still so hard to come by ... wish I could get my hand on some.

... when I search 4T I always end up on this old post of @alesh @SupraSPL and myself from 3 years ago (!) already looking for them ...

osram apparently doesn't sell by bins, but by batches, so you never know what you get

Yeah,

If you buy a reel of 2t-3t you either get all 2t or all 3t.
To (maybe) get 4t you have to buy 3t4t, and when you get them you'll know if they are 3t .. or 4t ..

I know that 2 years ago, Osram were still not producing enough of 4T relative to 3T for them to be reasonably frequent. It looks like things haven't changed very much ...

I bought my 3Ts 3 years ago, and they are still the most readily available top bin deep red ...

I believe we might see something similar with cree cobs now : less rolling out of new bins, but prices coming down gradually ... just me speculating tho.

Well after lurking and reading the LED forums the past two months I ordered everything and completed two panels.
Went with the CXB3590 3500K CD 36V and MW HLG-185H-C1400. Running passive.
This thread was great for design ideas, copied a couple that I liked.
I'm ready to build two more now, I'll have to wait until kingbright is back from Chinese New Year. I guess I can work on far red in the meantime.

How much heat do meanwell 240h-c1050 drivers put out? Comparable to a hps ballast? And if I wanted to keep the driver in a closet, do I just run the 2 wires from the series wiring all the way to the closet? Or is there a better way?
Thanks in advance

That driver puts about 13 watts of heat.
You can use loom tubing or braided tubing for you wires to run from distance for looks and more safety

I ordered it online. I can't see buying a brake or a shear. Angle in the corners. .063 aluminium. I'm sure this is the last I will build. To be honest the 8 vero 29's grows more smoke than me and my buddy can get rid of. 16 cxb's should give me better coverage. You can see from the avatar they work.

Here is a "passive aggressive" design, I drew it up to use the 90CRI 3000K CXB3590 available at Cutter. LED wattage is variable with an internal pot from 70 to 125W. The Giga also comes in 150mm length but the thermal graph didn't look that much better.

I've got enough LED stuff anyway but what makes sense in this format is: HBG-60-1400 (fixed @ 1400mA) + ModuLED Mega 100mm + CXB3070 for 50W at the COB.

I am yea. What do you think? The whole site is only about a week old.

Edit: To clarify, I setup the site, and have been working on improving functionality and creating a place for DIY LED Light design/pictures/videos, but it wasn't my idea, and we definitely can't do it alone!

I've used it and THANK YOU! :-)

It's amazing how expensive heat sinks are. For 3 - 36"(5.886"W), its $220, shipping included.I've searched high and low. It truly seems heatsinkusa.com is the only place to get multiple profile options with custom lengths.

That's what I'm seeing. I've contacted a couple of sellers on ebay to see if the can custom make a piece for less but I'm not hopeful. need to sketch it out on the same size piece of paper that I'm thinking of to make sure I'm ordering the right piece.
