Weird experiment…. Killing a halogen lamp whichh quartz bulb is already removed. So when powered the tungsten filament is exposed to air. I immerse the filament into a KClO3 + sugar mixture and then slowly apply power to the filament which will ignite the mixture….

The H 4 halogen lamp did survive in ice. I expected the quartz glass to crack but that didn’t happen. Surprised that the thermal stress on the glass 500° inside and 0° outside, didn’t cause a faillure as the outside normally is subjected to the air. I increased the voltage to about 17 volts , the lamp current was over 7 Amps! Then the filament burnt out.

I’ve always wondered what a 15k lamp explosion would be like. This is a shot of one NOT under load with a pellet rifle. I will always wear safety gear from now on…

This is Part 2 of a two part video showing how to remove, replace and install a head lamp assembly in a 1999 Camaro. This part concentrates on wiring a new Spec-D Tuning Dual HALO LED Projector Headlight assembly.

Here’s a demo and info session on a xenon metal halide bulb that I made a reflector for and use as a work/desk light. It was originally a HID retrofit kit for automotive lighting. Metal halide is a type of high pressure discharge lamp that is basicly the evolution of the mercury vapor lamp. It uses very similar control gear (ballasts, ignitors, etc) but adds various halide salts to enhance light output and color spectrum. They have the best color rendering index of all high pressure arc lamps, as high as 0.96, second only to xenon short arc lamps used in large movie projectors. They are second in efficiency in lumens/watt only to sodium arc lamps. They are commonly used to light areas such as gyms, sports fields, streets, parking lots, warehouses, and, of course, ice arenas. Current offereings in high output fluorescent lighting such as T8 and T5 fixtures are gaining favor for indoor lighting since they are more efficient, can output equivalent levels of light at high color rendering indexes, put out less radiant heat, are easier to maintain, provide more diffuse lighting, and are easier to implement in ways to enable various levels of light output for a given installation. This example is a xenon discharge lamp that uses xenon for higher initial light output to make it more practical for use in automotive headlights. The ballast also has a pulse start ignitor that is strong enough to hot strike the bulb, meaning it can restart when still hot from running. The voltage …
