Hello,

I am looking for a quality pulse metal halide bulb but I am a little stumped on where to get it, or if it even exists. I live in the US. The closest thing I've been able to find as a supplier is 1000bulbs.com. They do not have

So I get a call from my doctor customer. The guy I do weekend cleaning and maintenance for. “Can you replace some light bulbs for us? Bring a ladder” Sure, Ok. So I head down there and find out that it’s a street light in their parking lot that needs some attention. I’ve seen the private property street lamps before. Anodized aluminum box up on a square pole, usually about 16 feet tall. Fine. No worries. So I get out my 27 foot extension ladder, and set it up, and up it goes. And keeps going. And going. This is not a 16’ lamp pole. It’s a 30 foot pole. Yikes. So I set the base in close, a little too close for safety, and up the ladder goes me, the monkey. That’s when I found out that to my surprise, a hollow core 4x4 rusted steel square pole is actually quite whippy! So I’m 20+ feet off the ground, and the pole is going harmonic as a Honer . Eff uck dis! So it’s back down the ladder and get out my cinch straps. I lashed the ladder to the pole at about 8 feet and then again at about 20 feet. Cranked it down tight, and that took a whole lot of boingy-boingy out of things. Up the ladder again, and now it’s time to bend out into space to reach the underside of the light fixture. Turns out these boxes have a trapdoor plate underneath that holds the lens. To my delight they’re put together with a wire hinge on one end, and the trapdoor is held in place with 4 Dzus screws. Give each one a quarter turn and they unlock, and the trapdoor opens. The glass of course is utterly filthy, but now I can get at ... almost get at ... the bulb. And it’s a standard one. Amazing. Takes a 400 watt high pressure sodium. Which is pretty much the John Holmes of light bulbs , a glass cucumber about a foot long (including the base) and about 2 1/2” inches across. Comes out just fine. Now, where do I go to buy a new one?
