It doesn't list an output and there's no paperwork at all.
I really wanted to do 2 separate 10w lights, so I could put one on each side of the box for evenly spread Initiator lighting.

I could see those being a good fit. If u have an old cord around even an old cell charger u could try those first. So u dont have to spend more money

I was just looking for chips. One of these 660 chip (red) descriptions specifically says not to use a white light driver.

I need 4 of them though. 2 for 660's and 2 for the 730's.

Go for it! R u buying the housings and swapping em out?

I have all 4 housings, the 730's should be here any day now. I'll just pull off the OEM power supplies and retro fit the new ones. I definitely did this the hard way, but thanks for helping me figure this out!

Popped open Amazon today, power supply units expected delivery...Aug 15-30 
Pretty much guarantee I'll get baked and chop up old cellphone chargers before they show up. I hate waiting.

Just run a longer piece of wire between the 2 cobs to put them where you want. Use that method of both on the one driver.Popped open Amazon today, power supply units expected delivery...Aug 15-30

Yeah, that wouldn't be too bad. I might test wire it up like that and see what happens.

This can not work!
The driver usually used in this 10w floodlights are 17-38v @300mA. You need at least 4 of these 10w COB's and connect them in series to match the drivers minimum voltage. And with only 300mA per COB you can max-out there effiency.
Better is to use one of these 3-10v/900mA drivers. I need them to make my small top-seller, a 5w flower initiator using a 10w floodlight and a 10w/730nm COB for only 25 bucks.
.BTW, these 6v wallplug driver are constant voltage and would probably burn out your LED. I would not try it!
This is the ebay part number of the 3-10v drivers: 331625043383
Copy it in the search bar. Seller is Gracelight LED, 5,32$ each
and the driver fits perfect to 660nm and 730nm 10W COB's. 7w and 6w at the Wall!
Gracelight also have 10w/730nm for 9$/pcs.
Maybe you can get them cheaper at alibaba, who knows?

That's some good advice right there!This can not work!

and you can connect two chips in parallel to drive each 10w COB @450mA, ~3w.

There are also some new 2nd generation floodlights with 120lm/w instead of 90. I've not tried them but they seem to be cheaper as well!

Hold up, these LEDs are designed for DC current. If that's what you mean by "constant current" they will work fine...to a point. I have the 730s designed for 1000ma which is perfect. But I have the 660s designed for 900ma. 11% over, but maybe tolerable. Run time 15 min per day...remember that...not 12 hours.
