Mystery Ballast

Mystery Ballast

Click to view full size image

Electronic ballast inside of a Chinese wall pack. No lamp type, wattage, or ANSI code listed anywhere on ballast or fixture. Judging by the 2.3A current rating ide say 250w. I serviced this fixture as it stopped working.

The ballast actually wasn't the failure here, but the 150w Philips HPS lamp that was clearly overdriven and would no longer ignite. Unsure of what to relamp this cheap fixture with, I just put in a 250w Sylvania metal halide lamp and called it a day

With the plate voltage, current and power factor it yields 253W power input, so assuming the power factor figure is a worst case border, it suggest some 250W lamp.
As the output is rated just below 1kVpk, it won't be pulse start MH (they require more than 3kV), it look like just probe start MH or maybe HPS would be just on the border (usually HPS ignitors are rated to deliver 1.5..2.5kVpeak).
But electronic with probe start MH sounds strange - as the probe MH's are on the "politically incorrect" list...

So my guess would be HPS with 60% confidence or probe MH with 30% confidence (rest left open...).

I would guess for a real constant power ballast type (adjust the current so, the power stays constant), so it may actually cover multiple lamp types - the limitation would be only if they ignite on that and what is the output voltage range, where the ballast keeps the power.

No more selfballasted c***

I agree, electronic probe start does sound very unusual as probe start is being phased out as you said. The fixtures look identical to the Cooper 250w/400w wallpacks, but are a cheap Chinese knockoff. There is no label/sticker anywhere on the unit or reflector indicating a lamp type, and it doesn't even have a UL or CE sticker. The probe start Sylvania mh lamp I installed seems to work fine, but takes ages (10 minutes) to fully warm up

So then the HPS - lower current, higher arc voltage, if I remember well (mean the US market)...
