Merci Nap.,


Ok let get down to the bussiness I know few members allready addressed the issue.

Now the open circuit voltage will affect some degrees with the types of ballast due the MH use few verison the HX { autotransfomer reactor } is most senstive with voltage drop so any dip it will exigstish the lamp.

I useally get the CWA ballast if possible due tighter regulations so less chance the bulb dropped out which I know in Apartment complex is pretty good place to see voltage fluctioning.

The other thing with the bulb some are very picky with burning postion as well so you have to read the whole bulb numbers and letter so you will know which one you have.

The 70 W Metal Halide are typically are pulse start type so you will either see the ingitor or ingeraial with the ballast.

And check the wiring diagram on the ballast itself to make sure you have proper connection due some are pretty picky with operation.

Let us know what the issue.

And if you can find what luminaire name one of us will know the answer if that is good one or not.

Merci.
Marc

I'm actually getting more replacements coming in either tomorrow or early next week. I'm pretty positive I've got correct replacement lamps. However, the new lamps haven't had any problems yet. The lamps I used actually came with the fixture. I'll take pictures of the one I have since apparently I can't find the exact version online anywhere. I guess mine is an older version. I'm going to have to get a hold of a Wilmar representative and see if I'm the only one having problems with these fixtures. The new fixtures coming in will have all the component specs listed on a sticker on the side, so I'll be sure to have them posted here.

Ok you have 70 W Metal halide bulb with universal burning postion so that is correct one for this luminaire due this is a enclosed luminaire. the correct modern numbers will be MH70{w}U/E

I did add the E letter on the end due there is open luminaire rated bulbs as well due they will have diffrent concant button to prevent install the wrong one in the open bottom luminiares.

I will be wise to check with the luminaire rep to see if they have some issue with some batch of luminaires.

That kind of luminires we call them wall pack { there are quite few diffrent verison of wallpacks }

Majorty of them I dealt in USA side they are wired for either 120 or 277 volts but from time to time I will get them in 208 or 240 volts verison.

Merci.
Marc
