Hmm interesting... mogul base or medium? How efficient are SBMV lamps compared to incandescents or true MV?

Even less efficient than incandescent actually! Laughing

Cool!, I guess this was similar to the Norelco yardlight that used a 250W SBMV. Low wattage SBMV are about on par with incandescent but I believe higher wattage ones are more efficient than incandescent. The low wattage ones were mainly used as a lamp with a long life.
streetlight98   [Apr 25, 2013 at 02:06 AM]
if you combine the filament with the arc tubes wouldn't the efficiency be in between the two? i just don't know how well it really compares. i have a 160W SBMV lamp and it seems brighter than a 160W incandescent but i don't know if maybe it's just the color difference... what's the real benifit of even having resistive ballasted MV lamps? Neutral

aren't the lamps only rated for 1200 hours though?

I think the filament is waaay underdriven to prolong their life...

These have a medium socket in them.
