Hey all, I'm not in any way involved with them but have had good dealings with all three of these suppliers and found their service, prices and quality all excellent so wanted to give you a heads-up in case you're about to send more dollars overseas
3W Cree LEDs from Cutter Electronics in Melbourne - http://www.cutter.com.au/products.php?cat=Cree+XPE
The "royal blue" Cree XPE they stock are the brightest bin available, so best bang for your buck. Admittedly the red falls short of the desired 660nm, but LED aren't all that economical on their own so for flower I'd still be using LED as a supplement to HPS or whatever's working for you. I've got three light bars built with 7 diodes per 25cm long light (for a micro cab) and I'm totally blown away at how much light these suckers put out and how far the 3W diodes project their lumens. Get the diodes pre-mounted on isolated metal-core boards for 50cents extra or whatever it is. TOTALLY worth it, saves you stuffing around with krylon tape / copper tape or any of that bullshit. Glue 'em to a heatsink with some thermal paste (jaycar, cutter, ledsales etc) solder a wire between each and you're laughing.
Heatsinks from Conrad Heatsinks, also in Melbourne - http://www.conradheatsinks.com/ Excellent quality, also very happy with the service. When I finished building mine I ran them for 2 hours and after that time the heatsinks were still cold to touch. Masssssive overkill, perfect for our 40°C+ summers.
The part of the picture that's missing is a source of economical constant current drivers. These 700mA 15-24V drivers from ledsales.com.au are fantastic value for money and idiot-proof to hookup. If you're willing to run the blue/white LEDs at only 700mA instead of their max 1A, you can combine four royal blue and 3 red per driver. One driver, one heatsink and 7 diodes would keep a PC server case brimming with bonsai mums for ten years.
Peace
