Hello.
I search and search (Osram, Philips, USHIO...), but I do not find a suitable lamp (argh :-[ ).
I look for a 100W to 150W lamp (for a effective doublereflector-16:10-projector).
With only one round reflector are lost over 57% (minimum!) of the light (at the TFT past). Therefore I want to connect (segments cut off) two round reflectors.
2 times 250W is me too much energy. By the higher effectiveness 2 times 100w-150W should be enough.
It should have 5000K at least, better up to 6500K.
I do not find such lamp.
I know the 250W USHIO MH. Those would be very good, but she is too currentcorrosive (with 2 pieces).
I despair.....
Greetings,
Tobias Claren

All are a bit on the warm side with a temperature around 4200K but
have a good CRI and long life at a decent price. IEF and Ace like the
Philips and GE.

Hmmm, 4200K.
I found these lamps, but I hoped for higher Kelvin values.
I computed again the light losses in the circle.
1:1 (ideally): 36.18% loss
16:10 (WUXGA): 42.76% loss
8:10 (two reflectors): 37.88% loss.
37.88% light loss (1 large reflector) to 42.76% light loss (two reflectors).
Whether that brings much 🙄 ?
Then I could take also a large reflector..... If one was gotten..... Or an oval reflector. But I do not find a oval reflektor (with parallel emitting).

Strong Car-Xenons with ~6500K?
What is with xenon lamps (of car however strongly?)? There are no good lamps with good values there.
