Mike looking great i love the mixture BEER and LIGHTS

Ha, ha, thanks. My homebrew goes good with DIY. I'm reminded of an old Frank Zappa tune, T*tt*es & Beer!

Short blurb to keep the thread going. The 10,000K LEDs have started trickling in thru the mail, but project is stalled since I snapped the M2 tap I was using to thread holes into the heatsinks. Can't get another locally, so not sure this will be solved short term. I have BC Fasteners & Tools bringing in some #4 stainless screws by this Friday, so maybe I can use those to mount the LEDs to the heatsinks. #4 taps are easier to get locally than the metric M2, just not sure the heads on the #4s will be small enough. The fans on the heatsinks are actually attached with what appear to be self tapping countersunk screws, so that may be another option, but again, they're so tiny that they'll be just as difficult to source locally.

Lesson learned, use the proper lubricant for aluminum when attempting to thread with a tap. I was tapping dry.

I had a different approach, I used a CPU heat sink. It can handle four 10w led no problem. For this fixture I used a 30w 900mA and a 10w 900mA driver, both of them 85-240VAC supply.

I like that approach, pretty slick! So if I'm not mistaken you have 4 of the 10 watt LEDs mounted to one CPU heatsink & you've wired 3 in series & one independently? What's the colour combination, I see one blue or royal blue? The housing looks like a PVC coupling & not using any optics? And what about the nifty little swivel mount? What kind of screws are those securing the LEDs?

Please feel free to elaborate on the construction of your LED cannon! More details on the parts & how it's working for you. Don't worry about hijacking this thread, I'd like to see more ideas from people using these 10 watt or even larger LED arrays. I think everyone will benefit.
