High Intensity Discharge & Aux lamps.

Crappy video showing off a little module that allows the use of an auxiliary tungsten lamp which provides instant light when a HID lamp is running up and cooling down following a power interruption. This is for when any period of darkness while HID lamp systems are waiting to restrike is unacceptable.
Meh.
The HID lamp is 150w as that was the first ballast that came to hand when I was wiring it up but it could be whatever you wanted.
Aux lamp module is rated for a tungsten lamp of 50 to 500w.

After some testing, it looks like the aux lamp it set to cut out when the HID lamp voltage rises above 62v.

Interesting stuff!

Interesting to see the controller for this. I have seen this system used in railway stations in the past but didn't know if it was centrally controlled or as shown on each hi-bay.

A platform is probably not somewhere you want plunged into darkness following a power dip!

hi, let's try connecting a metal halide lamp to replace high-pressure mercury lamps through a quartz halogen incandescent lamp, but it may go out and the paw will not start or with the same high-pressure mercury lamp and try to run a 1000-watt metal halide lamp like this

@daviddesrosiers1946 2 месяца назад

Not a good idea to run that halogen without soda-lime glass shielding. Naked halogen lamps emit UVB and UVC.

I wonder if my setup came from a lowbay - I've never been able to establish what the long bracket that came with it did! I hadn't realised that aux circuits were still a thing in the (relatively) modern era - mine is 1983, and I thought that the setup only existed because older SON lamps and gear tended to take longer to warm up / restrike, compared to the later ones - you have educated me!

@@StreetLightOnline I have some big CDM lamps which run up and restrike in less than two minutes which is quite fast! Another win for LED is instant light output!

@@FrontSideBus That's impressive, given that MH lamps (generally) have a long restrike period. I remember being fascinated by xenon headlights when they began to appear in vehicles, given the rapid warm-up from a cold start. Yes, that is one definite advantage, though there's still something a bit magical of being on a SOX-lit road at dusk, and having *that* blood-red glow appear gradually in every lantern, and watching it transform into yellow over the space of a few minutes!

Settings on camera? Go to the shutter setting for 50hz or 60hz or auto and set for 50hz rather than 'Auto' setting, just a thought.

High pressure sodium lamp would be 70w ro 150w 🤔

150w as that was the first ballast that came to hand when I was wiring it up, but it could be whatever you wanted. The aux lamp module is rated for a tungsten lamp of 50-500w.
