Chris and David organised for some RGB modules to be sent to me as samples from Ray Wu. I little review for you all. 40mm dome covered modules Two types: 3 x 5050 leds and 3 x R, 3 x G, 3 x B strawhat leds Both type are very bright. Both types are very well waterproofed the board and leds are potted in epoxy. The 5050's produced the best colour variations during fades etc as expected. You can see the individual led colours on the 3 x R, 3 x G, 3 x B strawhat leds.
