90w-120w
halogen PAR 38 lamp has long been been the very good replacement for the 150w
Watt Incancescent lamps. 100w Mostly does so, but 90w is more commonly used.
BR/ER/R crap aside, you can even still get not needed 150w
PAR 38 lamps now when more efficient such as very long life or diechric versions as available still.
As a
fixture type, many of us in the industry in a small room have made magic with in help by a
PAR 38 can. Can replace with other stuff like a
PAR 46 if short snout more inkies, but not commercially available.
PAR 38 still has a slot in short
throw use I think and the 90
thru 100w
halogen flood versions would be best.
Gonna take another ten years before people like me and tons of others begin to loose the minds eye
image of what an
incandescent 150w
PAR 38 flood looks like in use. Was so a
base of design standard that it was a basic concept standard for design that everyone could see a mental picture for. Sorry, but if useful I have just short of two cases left of them.
To those that are not used to the 150PAR38FL, not a problem I suspect. For those that are used to it, the above at 250w, or under it at 90v would tend to lead to 100 or 120w.
Less a question about a missed lamp in lots more efficient options now, than a question of forced to change and perhaps too many options to choose from as the real problem forced into.
