GTL3 germicidal lamp

GTL3 germicidal lamp

Click to view full size image

This just came in the mail from China - I'm pretty excited. This looks like an ordinary incandescent lamp, but it is in-fact a low-pressure mercury vapor lamp. When the filament gets hot enough, a mercury arc strikes across it (think preheating an ordinary fluorescent lamp).

This is a UVC lamp, so safety precautions must be taken when running this outside of its intended application.

These are spec'ed at 10.5V by 0.3A. Does anyone know if these are okay to run on an electronic fluorescent lamp ballast; something like a Fulham Workhorse 2? No problem on the current front; I just don't know if the high OCV vs. the low arc voltage is going to cause any issues. All my other lamp-testing gear is back at my Mom's house.

Update: It lights up just fine on the Fulham Workhorse 2. Very pretty to see. Will upload lit photos later.

These are nice lamps and interesting to watch in operation!

There are many different architectures of electronic ballast, and while some will certainly work, I think that most will struggle to regulate the lamp power at such low voltage. Normally these lamps should be used in series with a standard magnetic ballast for a 4W 6" miniauture fluorescent lamp.

I think this should work with 40 Watts 120 Volts incandescent light bulb in series, but it might overdrive by 300 mA

Pretty, please no more Chinese failure.

I tried it on the Fulham Workhorse 2, and it works perfect! Very pretty to see. From under a drinking glass, of course.
