I've replaced the LEDs in both my Sunbeams. Easy. Pull the old ones out, put the new ones in. The original ones have three pins (for the dual-color) and it took me a couple tries to get the two pin LEDs I bought to work right. I didn't try too hard, but I could only get the LEDs to power at either 0-7v or 7-12v. This was okay by me, as I usually have my fans turned to at least half so I get the LED from 7v and up. The process took about 5 minutes total, and I like the dimmer LEDs that match my lighting schemes better than red/blue. (Purple LEDs on one, just red on the other).
