$60 That's better then i found, but is there any chance of getting cheaper Taiwan or China models?
Hi ebp.. First, yes, it still works fine, and I use it a lot. For instance as a high luminance source in one of my optical test benches (building telescopes)
I also tried some cheaper china bulbs, but they were absolute crap! Only Welch Allyn managed to build a well performing 10 watt HID..
With the low 10 watts of power, the thickness of the bulb is very important! The cheaper Taiwan or Chinese bulbs are much thicker due to the cheaper
manufacturing process, and there is the biggest problem: Those thicker bulbs do not warm up hot enough to sufficiently evaporate the ingredients,
so compared to Solarc, light output is very poor.
Welch Allyn succeeded in making the bulb thin enough to reach the desired temperature, but at the same time cope with the huge internal pressure.
With higher wattage bulbs, this is less of a problem because there mostly is sufficient power to make the bulb reach the desired operation temperature.
The Solarc 10 Watt HID bulb is the smallest reliable HID bulb on this planet..
