Check these out. Scroll down to pics. All you need to do is hang them and connect the power cord.
~ 150 plug-n-play watts for < $400. Very promising, but I'm holding out for replaceable cobs/chips. All these offerings the chip/cob is not designed to be replaced

There outta be a law

If the chips are mounted in something like Molex connectors, then yes, but are they? Seems like the chips/cobs are solidly secured to the heat sink, so how do you propose to swap them out without some skills and proper equipment?

^^^^^ it would be cheaper to buy the Apollo cobs (multichip) on amazon. Then swap in better cobs

What about not having a hot enough iron, or winding up with hot spots, or.... Speaking for myself, any of these presents a problem that I am ill equipped to resolve, or...

Here's where I've been in the dark, does the thermal paste harden, or does it stay pasty, so that the cob is easily lifted from the heat sink? If that's the case then yeah, but most of the cheap light heat sinks are only good for low wattage cobs, and may not handle a higher quality COB that can be driven harder *though it may not need to), and then you need a bigger driver too, right?

See, I have so many questions, any one of which could trip me up

Why do we need to buy a casing? Mount or hang these single cobs on rails

screw driver, solder gun. ore replace the entire inside. just buy it for the casing

It hardens. it should act like solder. It shouldn't be an issue with a solder gun. Then again it could be some cheap ass no name paste made in china

you could add a larger heat sink and make the drivers remote. Less heat over the canopy

I spent a couple hours on Alibaba yesterday. I think the solution (for me) is to get Down Lights, which are complete and come in CW/NW/WW

All that's needed is to hang them from the included hooks to any kind of rail and wire the ends to the power cord

Just looking for wattage and small enough quantity + free shipping to pull the trigger. At the prices I'm seeing, < $200/~4-6, I can afford to replace them after a couple grows, at which point more of this should be sorted out

None say actual draw. Are they the same as grow lights (~50%)? I emailed a few

CREE? No? in the specs some say Epistar

Seems to have a bigger reflector, good for WW

Some hardens, some stayz sticky...in my experience the 'non-adhesive' stays sticky and the 'thermal adhesive' goes harder....

HEY! I use cheap no name Chinese stuff! :)

Do you know anything about the eshine 5G? In the video they show one cob being taken apart, and the COB comes out by hand- no grease. I inquired but no response yet. Also inquired about $$$

Nah...i dont know shit about any panels really...maybe it was just for video purposes?

I suggest you get:
5 w cobs >>>>>> http://www.aliexpress.com/item/5W-COB-LED-beads-Warm-White-3000-3200K-Pure-white-6000-6500K-surface-light-source-300mA/1457717574.html
Driver >>>>>>>>http://www.aliexpress.com/item/Mail-Free-1PC-4-5-x-1W-Input-85-265V-Output-8-17V-300MA-50-60Hz/603873892.html
Heatsink >>>>>>>>>>>>>>http://www.aliexpress.com/store/126942 (talk to Dylan...he is awesome..)
Thermal adhesive >>>>>>>>>>>>http://www.aliexpress.com/item/3pcs-lot-Thermal-Conductive-Heatsink-Plaster-Viscous-Adhesive-Compound-Glue-For-PC-GPU-IC/1062672566.html
40w solder iron (good power for electronics) Im sure any of your local hardware outlets would carry them

Now...these are the basics.....but you can fuck around with cheap components to get your DIY'ing confidence up...thats how i started...That way you dont have to worry about your concerns of 'hot spots'...or having the right equipment....because there really isnt that much to get

........We'll return to "Lost in Shenzhen" starring PetFlora in a moment. And speaking of China has anyone seen this? What's this, "this"? ADJUSTABLE BEAM ANGLES BITCHESSS!!! Me likey, lens/reflector based or not. Someone get Eraserhead in on this. :)

Stolen shamelessly from LEDs Magazine:
http://buyersguide.ledsmagazine.com/haichang-optotech-co-ltd/p/rotatable-led-down-light-beam-angle-adjustable-1060.html

http://www.haichanglight.com/product/18w-angle-variable-led-downlight.html


Now back to our show, where we find our hero realizing there is no BBB in China and that he should have listened to the wizened wizard of the south, Chronikool, after all.
