Sylvania BA 575/2 DE BriteArc Lamp


Here is an interesting little lamp; I believe it to be intended for studio and entertainment lighting, but I'm not aware of the type of fixture it would use, and I can't really light it until I find one..! I would appreciate any information on this lamp, please.

Yes, it would be nice to see it litted Cool

Looks similar to the Sharxs HTI lamp I have, which is also from the entertainments industries.

With an arc gap of 7 mm, it is more akin to HMIs whose applications include effect, studio/theater, and architectural lighting (the HTI is a high-brightness source aimed at applications requiring a high degree of optical control, such as in pinspots and for image projection). Your /2 BrightArc lamp is a special type with an 8000 K light color temperature and a CRI of 70 Ra8, better suited for moving head projectors and effect lighting. As for its specs: 95 V, 7.0 A, 575 W, 44 klm, 1 kh life, universal position. If you plan on running it, don't do it without protection as this lamp radiates 100 W of UVs! And there's always the risk of burner rupture... Those lamps are really nice, but running them safely takes some efforts.

Thanks, I think it'll stay a display lamp, then Mind Blown
Unless I can find an appropriate fixture, that is Wonder

You should give it a shot still, it's always nice seeing those lamps in operation. Their huge brightness and massive light output really gives you a sense of what raw power is (use welding goggles and sunblock Wink ). If you're looking for a remedy for SAD, that BA 575/2 DE is a good one lol.

Hmmm, I'll think about it. What would you suggest as a suitable ballast..?
Max   [Mon 08 Dec 2025 at 08:21]
A 700 W HPM ballast should have a right impedance (25 Ohms) to drive this lamp. If you don't have it, you can get the same ballasting impedance by connecting two chokes in parallel: 400W and 150W HPS, or 400W and 250W HPM. Otherwise you could run the lamp at a lower power level. In any case, you should also provide some ventilation to keep the lamp from overheating (running those lamps has a lot of constraints, I know).

Thanks, I'll give it some thought.
