Always learning new tricks.. "DON"T LOOK @ ME!..LEAVE ME ALONE!"
Journal : http://www.rollitup.org/blogs/380148-ringsixty.html
After reading SXs comments regarding Cree whites on another site I have been very curious to see how well a white only set up works.
Any particular reason for not using say 4 X 25 watters and spreading them apart?

They do seem to be working and if I have half decent results I might put together another panel in which case I would likely go with smaller arrays supplemented by a few colored 3watters all mounted to a nice long single heatsync. I originally had wanted to go with smaller white CREEs but ended up at ~$750 for 200 actual watts compared to my $180 for the same wattage - just couldn't justify it to myself. In my mind the difference of $570 is better spent by just running more wattage - in fact I could run an additional 200w of cheapo LED 24hrs/day for 989 days and it would still be less expensive than going with half the wattage in CREEs.
I may not understand 75% of the more in depth LED conversations that happen in this forum but I am mechanically inclined and have a solder gun and wouldn't mind tinkering with my own DIY panel if I could get a little more understanding and what was required.
Thanks for any input, Gas.
Here's a list of everything I purchased:
1x 100w cool white array - http://www.ebay.com/itm/300639533243...84.m1439.l2649
1x 100w warm white array - http://www.ebay.com/itm/330660077325...84.m1439.l2649
2x 100w constant current drivers - http://www.ebay.com/itm/330660091340...84.m1439.l2649
2x 5.88" x 6" heat syncs - If I were to do it again I would go with slightly larger. And keep in mind that heatsyncs vary tremendously, for instance these are ~3x the weight of other similar sized syncs - http://www.heatsinkusa.com/5-886/
1x Artic Silver 5 99% silver thermal compound - http://www.radioshack.com/product/in...ductId=2216879
2x $0.89 extension cords
Tools I used and other small stuff I had on hand:
Solder gun and solder
Screw driver and screws
Drill and drill bits
Electrical heat shrink, electrical tape, or wire nuts.
I'm pretty sure that covers everything. I added a reflector I had laying around and cut up some 24oz aluminum cans for reflectors but I wouldn't say that's necessary
Later today/tonight I'm gonna take an in depth look at the components and I may have a few more questions for you.
It looks as if I need the array(s), driver(s) & heat sink(s) and that is all. I have everything else on hand. So I may have found myself a little project.
Oh, Do you have any type of diagram or a link to one that shows the actual hook-up and what goes where? I'm not sure if that is a basic question or not, I'll be sure to look that up as well if I don't hear from ya. Again, Thanks!
Can I put this in my signature: lol

Thank you very much also for the part list, with links !
Did you mount the chips with nuts and bolts or did you make threads ?
( I see one screw line up with a fin, but I'm not sure)
And have you found a name for your two lights, or shall I just refer to them as Gastankers Liberty Bell 2700 and his Grapple 6000
Not sure why but you solder to the rails on the sides versus the more apparent positive negative contacts. The rails are identified by comparing which side they favor. So the negative will be connected slightly more closely to the negative end (labeled)... The ballasts themselves are labeled so they aren't much of an issue.
Let me know if you need anything else clarified.
