DIY RGB LED Light Fixture - Novice needs your help!

[tomstav]

Hi Guys,

I'm hoping someone here can help as I have searched the web all night with no luck! I know absolutely nothing about LEDs but am determined to get this to work!

I am trying to make a remote controlled single 10W LED spotlight to put over my fish tank... I want this to be a controllable RGB light so that I can change the color with the remote. This will be purely for aesthetics and not to support plants/corals. I don't want to use the pre-made LED strip lights as I want it to be a single hanging fixture.

Right... So here are the components I have...

• Outdoor 12V Transformer Power Supply Adapter LED Driver IP67 Waterproof 10W - This is plugged directly in to the wall and outputs to the following controller.
  

• 18A Wireless RF Remote Touch Panel Controller For 5050 LED RGB Strip 12V Switch - The controller box then outputs 4 cables (red, green, blue and black), these would typically go directly into a standard RGB LED strip light.
  

So, now my goal is to (if it's even possible) connect these 4 coloured cables into a single 10W RGB LED chip. I have bought the following two chips hoping one of them would work...

• 10w Cree XLamp XM-L RGBW RGB White Color LED Emitter 4-Chip 20mm Star PCB Board
  
  
• RGB LED Light Bulb Beads 10W Lamp Bulb 1pc High Power Super Bright Integrated | eBay
  

Will either of these chips connect to the 4 coloured cables? If so, how do I connect them? If not, what kind of chip should I be using?

Any help here would be greatly appreciated!

Thanks!
Tom

No. Unfortunately, the controller is designed to drive LED devices that have built-in current limiting and are thus made for a voltage source. Neither your controller or the specified LEDs have a current regulating function.

Thanks KJ6EAD for your help and quick response!

Using this controller that I already have - is there any simple configuration that I can do to achieve a 10W RGB LED fixture?

If not I may just have to use a strip of LEDs although I would much rather have a single floodlight/spotlight fixture.

Many thanks!
Tom

The type of LED you're interested in is usually driven from a compatible constant current driver. Some can be controlled by the (presumably) PWM output of that controller. Google is your friend but as you probably realize, not much useful technical data is offered by most ebay sellers.
