From http://www.philipslumileds.com/products/luxeon/luxeonrebel we see that the Rebel LED produces about 80 Lm for a bit over one watt of power, (knowing that its drive voltage is a bit over three volts DC). They are now clearly more efficient than CFL's. Longer lasting, less heat, more rugged, and greater functionality, too.-Ken _______________________________________________ Liveaboard mailing list [email protected] To adjust your membership settings over the web http://www.liveaboardnow.org/mailman/listinfo/liveaboard To subscribe send an email to [email protected] To unsubscribe send an email to [email protected] The archives are at http://www.liveaboardnow.org/pipermail/liveaboard/ To search the archives http://www.mail-archive.com/[email protected] The Mailman Users Guide can be found here http://www.gnu.org/software/mailman/mailman-member/index.html
