I just bought the 1000w MH lamp and I see this white stuff and a blob of glue looking stuff in the middle.. Is this how it's sepose to look or we got something wrong here.. Have not even plugged it in yet as I need a figure how to connect my ballast to the bulb

i would say that is a manufacturing defect, a drop of glue or solder that got on the glass and didn't get cleaned off. i would return it for a trade if its at all convenient. it may work and it may not, but whatever that is will cause a hotspot on the glass and could make it malfunction, or even break the glass when enough heat builds up.

oh, and to connect the ballast to the bulb, you need a hood of some kind. actually, you need a Mogul fitting,
can do without the hood, but it makes it 1000 times easier to deal with if you have a hood or cool tube, and makes venting heat sooo much easier

Yea I'm just gonna buy a cool tube aswell.. They say all their ballasts are compatible with their hoods. I Just hope the cable will be long enough if it even comes with one.. I should enquire before I order again but they don't work mondays

be careful using the one in the picture. like i said, it may work perfectly, or it may shatter when it gets hot enough, and send a load of hot glass and bits of tungsten into your fan and vent hose.
