lazaah Posted February 16, 2011 Share Posted February 16, 2011 Hello, I am looking to light my 1sqft tank with 3 CREE XP-E Royal Blue 3W and 2 CREE XP-G Neutral White 3W. Probably buy them from rapid led unless theres somewhere more convienient. Ive noticed their drivers are only suitable for 8+ leds. What do I do about this? Id like to be able to dim the colours so I dont damage the coral, should i just worry about dimming the blues, whites, or both? Cheers for any advice Link to comment

Cheers for any advice I am looking ot purchase from there too, same thing 3 Cree RB and XP-G NW. Sort of in the same boat. Evilc66 Said something about two buckpucks to do the job. Link to comment
RK_tek Posted February 16, 2011 Share Posted February 16, 2011 buckpucks will drive 1-6 leds. if you want to be able to independently control the color temp, then get dimmable drivers for both, they are only a dollar more than non-dimmable and allow you to acclimate corals or just turn down the brightness if it's too bright.

lazaah Posted February 16, 2011 Author Share Posted February 16, 2011 Can you suggest a buckpuck sorce/brand? dont see dimmable ones on ledsupply or rapid led Link to comment
Mr. Microscope Posted February 16, 2011 Share Posted February 16, 2011 Here's the 1000mA one with a pot for dimming. There are others there too though. http://www.ledsupply.com/03023-d-e-1000p.php Link to comment
lazaah Posted February 16, 2011 Author Share Posted February 16, 2011 OK well heres my shopping list, is this exactly what i need minus heatsink and fan, or am I missing something? From: ledsupply.com x2 3023-D-E-1000P Wired BuckPuck, 1000mA Output, DC Powered w/ Potentiometer $39.98 x2 Aluminum Potentiometer Turn Knob $4.98 x1 12VDC 2.5A 30-Watt Power Supply $14.99 From Rapidled: x3 CREE XP-E Royal Blue 3W LED on star $18.75 x3 CREE XP-G Neutral White 3W LED on Star $20.25 x3 Solderless Connector for CREE XP-E LEDs $4.50 x3 Solderless Connector for CREE XP-G LEDs $4.50 x1 Arctic Alumina Thermal Adhesive $6.99 Also can the solderless conntectors be used with the thermal adhesive rather than drill and tapping the heatsink? Cheers! Link to comment
Mustang Boy Posted February 17, 2011 Share Posted February 17, 2011 it looks like you would have to drill and tap the heat sink in order to get the solderless connectors Link to comment
lazaah Posted February 17, 2011 Author Share Posted February 17, 2011 it does look like it but can anyone confirm? logic says that the leds still need to make contact with the heatsink so expoy would work instead of screws Link to comment
Mustang Boy Posted February 17, 2011 Share Posted February 17, 2011 yes but it looks as if the solderless connector is held to the LED by the screw that holds the LED to the heat sink. when you use a screw to hold an LED to a heat sink you use thermal grease to make the thermal connection to the heat sink.
