I bought the particular set off of eBay for $20. I've bought several sets and this one was different. The first couple of led strips were 5050smd leds. They each had red leds, green leds and blue leds. The eBay set I put on the trailer has true rgb leds. Each led does red, green and blue. Much brighter than the previous sets. I don't know how to tell you to determine which set to buy. Do NOT buy 3528smd leds. Lower power draw, but much dimmer. Ask the seller before you buy if these are true rgb leds. Don't get me wrong, either set is nice, but the true rgb leds give allot more color options and the white option. That said, if the 44 key remote has a white color button, it should be true rgb.
