Hanging a HID high bay fixture as a long chain swag pendant light? « on: September 01, 2024, 12:14:36 AM » Author: WorldwideHIDCollectorUSA
Since I have been thinking of collecting some high bay fixtures for the sole purpose of running certain HID lamps in a base up configuration, I am wondering if there are any ways to safely hang a HID high bay fixture to the ceiling by using a swag lamp kit or are there any heavy duty chains and swag hooks that can help support the weight of HID high bay fixtures without having to remotely ballast them? I personally enjoy the look of HID high bay fixtures whenever they are oriented properly with the lampholder mounted base up. I would like to make sure that the fixtures do not fall from the ceiling or cause any damage.

In your home, I wouldn't recommend you to use a long chain, because the ceiling is much lower than in a factory, GYM, etc. Your highbay would be to close to the floor. The gear compartment should be ceiling mounted, and I don't think it is possible to do this with a long chain.

This could be done in similar fashion to a plant grow light, where the ballast is remotely connected and sits on the floor. Then the luminaire is lightweight and mounting is basically like an incandescent light. But with full-wattage HID, it may be too bright at such a low mounting height and look very disproportional in the room. Mounting a high bay as-is with the ballast still in it would mean using heavy chains, hooks and bolts and making sure it’s fastened well into a ceiling stud. You’ll have big holes to fill when removing it later. Another thing to be concerned about is lamp heat if mounting close to the ceiling.

With remote ballast and pulse start system, make sure the ballast, mainly its ignitor, is able to drive the cable length to the lamp. Standard ignitors are rated only up to 2m/6' cable length, for anything longer you need some high energy ballast/ignitor. It should be mentioned in the ballast/ignitor datasheet. In Europe you may use remote ballast, with a superimposed ignitor placed close to the lamp into the fixture. US systems usually use semiparallel toplogies, there you are stuck to what the lamp+ballast combo is rated for (there the ignitor pulser module should always be placed close to the ballast). Technically you can disable the ballast built in ignitor and use a superimposed one in the fixture as well, but unless your lamp may use some European spec ignitor (arc voltage close to 70..130V range, ballast OCV in the 200..250V range), you may have trouble finding such suitable ignitor.

No more selfballasted c***

It is also good to know that the Japanese HID systems often use self starting lamps and also some pulse start ballasts that utilize built in ignitors as far as I know. External HID ignitors are hard to come by in Japan as far as I have seen.
