Sylvania H36-15GW/W - Back to life!!
|
This is one of the two 1000W /Ws I got last summer, the other is almost unused, although this one wouldn't light, even on a HPS ballast with ignitor. I forced things a little and ran the lamp on a power-limited MOT with likely over 7kV open circuit. Running it a minute on the MOT allowed the gases in the arctube to heat up. I immediately switched the lamp to the HPS ballast. Upon applying power, a shaky, flashing arc appeared in the arctube, and stabilized within 5 seconds into a soft, steady blue discharge!
This experiment was kinda successful. After 5 minutes running at full power, it went out for some reason. The lamp would still start after cooling down, so I guess it was caused by a poor connection somewhere in the circuitry. The lamp of course will not start without the ignitor since this S50 ballast alone only gives around 200V open circuit, while the lamp needs over 400V. I can't wait to get a H36 ballast!

But your Bonusline was far more dead than my Sylvania merc. Mine would still give a very dark purple glow on the HPS BALLAST! XD I still wonder what you did to your Bonusline merc though!
Plus there are a few lights that are at exits and no way they would be still working if they were started everyday since when the mall was built
i found an effective method for ballasting a MOT is to feed 120 V into the 240 Side of a 240/120 Transformer and connect the MOT to the 120 side...i didn't measure current but it was a big enough reduction to keep me from popping the breakers...it was probably still a signifigant current as the Step up transformer got pretty warm after about 15 Minutes and it was a 1 KW one.
also looks pretty bright...or is the camera fooling me?
