Played around with some, but didn't like the results much - too "on and off" and odd looking for general application. Did use them and leave them in the AFM mothership - the 89 in there blows constantly from the ship being bashed, and an array  looks sensational in there. We used a lot of LEDs in Coconut Island (for ease - the PS 5volts was used) but too dim overall. I'm not a fan mostly, although I have seen some good looking efforts.
