HID is not incandescent so power does not have the same effect. When 35 watt D2 HID bulbs are first started in automotive application they see over 100 watts. They are overdriven to accelerate warm up. A 35 watt bulb is very capable of being run long term at 50 watts, the life is derated (shortened) by about 30%. When considering the bulb life at 35 watts being near 3000 hours this is an acceptable trade-off especially for this application.
The wattages of the bulbs are established for certain life ratings. The bulb we use for 75 watts can be run much higher (80-100W) than that but would require suplemental cooling to maintain life. Our 75 watt bulb gets similar life to a 35 watt driven at 50 watts.
Thanks for the info... "you must be Dan?"..
So can you tell me simply... the existing Xevision spotlight that is available in the 50W version... what are you getting when you buy it?.. a 50W bulb or a 75W bulb driven at 50watts?
That may answer this next question:
If and when you provide the 75Watt light... I assume it will be the 75watt bulb driven at 75 watts?... or will it be a 50 watt bulb driven at 75 watts?
And while I'm asking.. what is the expected runtime on that 75 watt version?
And since I am intending to buy soon.. do you expect it out soon?
I also am not trying to pin anybody in, I think communication "the beauty of this forum" is the key way to stamp out misunderstandings and shed light!
I just want to make an informed buy and know what the lifetime bulb expectancy will be based on my choice as well as runtime.
People obviously have different needs and budgets.
I appreciate the availability of aircraft lights in a spot light!
Some will buy it for the extreme reliability and others will buy it for sheer performance.
I've seen people buy those lasers and immediately start trying to tweak them to make them stronger without regard to lessening the life.. others wouldn't dare as the life is important.... especially if you want to maintain the quality over time to make the money worth it.
