                on the back of the leds as you probably know you have to match up the anode and cathode pads as they are two different size pads you can remove a led and test which one is which. wattage wise im not sure maybe budm will know?

                    Did you measure the Vf of the working LED?

                        Do you have LED tester?
                        You also need to verify which pad is Anode and which pad is Cathode.

                          I dont unfortunately, I have ordered one but hasnt arrived yet, so far Ive always just used a home made battery and wire/probes setup to test if LEDs are functioning.

                          In regards to anode/cathode, please see attached pic.

                          Another eBay seller has just messaged and has advised that these are the ones I need. Could you confirm he is correct please? Have more faith in you than an eBay seller lol
