And that's without the infrared that a halogen or discharge lamp has. Very efficient and low maintenance. Stronger than HID car headlights or a 500W halogen. Hit the site for lots of data and pics of it in action including burning and irresponsible bicycle luminosity. You'll want one to attach to your keyring, too."
