I would be interested to know if they are still selling this 100W unit, because since then I have "degenerated" to using only 50W and I would prefer more Watts. Some remarks on the your search for the ultimate spot beam. Does this assume that you want to use the narrow beam to illuminate the runway from some large distance on finals?. Do you really think so? If it is that narrow, then any variation on finals due to crabbing for any cross-wind or difference in angle of attack due to variation in loading/CG, will cause it to illuminate not the runway but the local wild life watching with interest from the long grass! My opinion is that the most important function of landing/taxi lights is TO BE SEEN , NOT TO SEE ! Therefore I would go for a wide beam which everyone, especially the tower, can see - even in daylight. Wattage is more important than beam width. But that maybe just my kind of flying environment Regards, Colin Jones PH-COL (320) >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LML homepage: http://www.olsusa.com/Users/Mkaye/maillist.html
