That's why I put it in quotes! The link and the title both use the dreaded "
Bulb" word!
Parabolic actually refers to the
reflector style (
Parabolic Aluminized
Reflector.) As for FFN, FFP,
Etc., Who knows where they came up with those. Someone once told be the N was no finish, and the P was a pebble finish. (What is R? Rough?
)
The real thing I would like to know is if they are even
Halogen. If not, then degradation of beam from blackening of the
reflector will be a big factor as the lamp ages. If it ages !
Expect they are
halogen (fill pressure of it in question in balance not for lamp life but output..) and given we are taking their published lamp output for
CBCP, we also have to take their lamp life as similar for accuracy which would be
halogen grade. Color temp. also matches up.
Halogen I think yes, just not as good for output.
"
Bulb" should hear my guys bitching and moaning about inventory this week as a bi-anual thing now. They
point out the box of the lamp says "
bulb" thus I'm insane.. yet they use the term in understanding the concept when not spiting me use it as per "lamp" but still like to challenge me on it.
Main question in buying such lamps is if the data is accurate - said to be wrong or wrong in question. If wrong in data perhaps fine enough lamp... perhaps - many vendors do bad specs at times initially. If accurate, could be fine say in a theater where you don't need the output persay and need cheap lamps. Lots of wasted wattage in doing so but if the choice, it's a source for lamps. Kind of the reverse of 600 or 800w high output lamps for
PAR 64 now long gone given they are at 1Kw but less output, and the lesser wattage ones were more or the same at least output for less wattage. Moot pont, gone now such lamps.
The most cost effective
PAR lamp
Bubble these I think these days is the Osram AlumiPAR range of lamp. For me, way too many normal bubbles in
stock to try something different, but were I starting over, that's what I would go for. Better lamp given one has missed the other discontinued versions that were also better but lacked purchases of in buying. (Part of the above inventory is many 600w VNSP lamps that will sit in inventory for many more years without use.)
Overall concept... a 1K
PAR 64 lamp is very powerful. If for a large enough theater, could be fine but I would expect that for most uses it would be over powering.. Many newer theaters have enough
power so a sub-standard output lamp could be fine in it in wasting energy but doing it's output at that
color temperature. Kind of like a lesser wattage lamp only this at more output and wasted wattage for perhaps sufficient output for the needs.
Don't know but possible that this lamp could work. Less efficient but cheap and perhaps within the maximum output needed for the use. Not an efficient lamp by the specifications but perhaps a not energy efficient fill the gap similar to what a 750w
PAR 64 lamp could do were there one, which perhaps would be more useful for this situation.
One can never tell the situation needs. Thought perhaps?
