This power star LED is a high luminosity module that is mounted on an PCB substrate. Being more energy efficient than incandescent and most halogen lamps this LED is ideal for a wide range of applications including: electronic signs and signals, small area illumination, back lighting and other lighting, bollards, security and garden uses, traffic signalling and beacons.
(May require an additional heat sink, depending on application).

Q. Hi I am planning to convert a couple of 12v Ray boxes from halogen to white LED, 55-2239. I calculated that I would need a 22 ohm resister, 4 watt.. Would you agree, and what resistor would you recommend.
A. Hi John, thank you for your question. 22 ohm would be suitable, something like 62-0250.
Q. I'm planning on using the white LED with a 9V battery to make a simple torch what resistor would you recommend?
A. Hi Craig. Thank you for your question. A 30 ohm resistor would be suitable, something like 62-8328 would do the job.
Q. Is there a heat conducting adhesive that can be used to fasten these LEDs onto a metal substrate?
A. Hi Chris. Thank you for your question. We actually list the PCB star heat sink for this LED (55-1991) which requires just bolting on with heat sink compound. Failing that we list a Loctite adhesive kit on 87-0328.
Q. Which driver would you use to drive just one of these LEDs and if a resistor is needed which would you recommend? Regards Neil
A. Hi Neil, we would recommend 55-2224. This would require a resistor, the value would depend on what colour LED you are using. https://www.rapidonline.com/12V-Constant-Current-LED-Driver-300mA-AC-DC-55-2224
