Gosh darn it. Steve, now I hafta ;-)
OK, I'll pick up a set later today, put them on my light bar, and try them out on the drive back up to Minnesota this weekend.
Actually, this has got me thinking... I'm working on a design for a multi-channel, intelligent heated clothing controller. I could use one or two of those channels at a high modulation rate to control the intensity of LED lights. That way a set could be used as DRLs (low intensity), in-traffic augmentors (medium intensity, to go with low beam), and nighttime highway lights (high intensity, to go with high beam).
I went on the Optronics website for more info on these things, but the site is woefully short of real information: there isn't even a beam pattern description or a lumens rating. I emailed them asking for info, saying that if they want to sell the darn things they need to provide information.
