Iwasaki lamps

[TAC]

I remember seeing a discussion about two different types of Iwasaki 250 watt 6500K bulbs. Can't find it now, and am about to order some. Does anyone remember the distinction and how they are designated. I know one is the MT250DL, but the other has two more letters, and as I recall, is the prefered one.

Thanks

As I remember this...

DL is the daylight designation

The other designations are for the bulb postition

BH Bulb horizontal
BV Bulb vertical
BU Bulb universal
