If you want something smaller for the bike then check these out Motorcycle LED Lighting 3500LM 12V Cree X2 ****le MY Ride Advrider Tiger 1050 | eBay
They have been getting very good reviews on the adventure touring motorcycle forums. Apparently the 1600 lumen are more than enough even for daytime use. The 3500 need a dimmer for sure.
