Just got to thinking if when I do retrofit if the 250 watt metal halide will produce as much heat as the 410 w FXL halogen or if it will be less. Hopefully less then, the halogen makes the room scorching in mabe 10 min. any thoughts?
The ame amount of Light, I would hope not It would defeat the purpose. According to the specs Im reading the Double ended Bulb gives off a min 18,000 and max 20,000 Lumens, So I would hope that once It was pased through the optics and LCd I would end up with 800-1000 left of brightness. Sorry if the above sounded condasending, Yea I know what you mean about it being more efficient, Hopefully It will make substantially less heat, In the winter Honestly I can have the registers closed in a 15' by 20' room and in 20 min the room is 75 from this one stinking little bulb. and in the summer thats not a fun thing( unless you live at the north pole).
Only potential problem is that going to a 250 MH setup is that you might have the same gross lumens as the 410W FXL bulb...you do loose some "efficiency" gained by the built in reflector that the FXL has, wheres most likely you have to use a makeshift reflector of some sort that isnt optimized the way the FXL reflector is.
So net result is you have a cooler setup, but have the problem of directing all of the light

yea thats one thing I was wondering about, But wait dont all older OHP's use a Bulb thats at the bottom of the OHP and the bulb is seperate from the reflector( thats why Older ohps are so HUGE) so couldnt I just take out whatever lights are present and put the Spark gap directly in front of the Reflector thats allready in the OHP?
there is a 400W EVD bulb that a lot of OHPs use...these have separate reflectors and optics to concentrate the light
But a lot of OHPs also use FXL bulbs and this eliminates the need for a reflector/some optic setup in some projectors (and thus lowering manufacuring/design costs).
Never assume that all old OHPs use the same type of bulb setups. I've seen some crazy setups in the types of bulbs old OHPs use.
