Hello all. Need some electrical help with this ballast. It is a multi tap and I'm going to use the 120v tap. From the diagram that's listed in the link below...
The capacitor is for power factor correction. The ballast will work properly without it, (it would then be a Normal Power factor circuit) The line voltage is...
When I was at Golden Gardens beach tonight, I looked across the sound at the clouds on the peninsula, and saw how they were lit from below. There were three...
Maybe not! I've seen that effect round here, this area is all LPS/HPS, but there are a couple of sports fields lit with MH and they spray white light all over...
I would bet that's what it is. There is a sports field across the Sound, in Kitsap County that I can see the lights from as far away as Edmonds. The glow could...
I've been seeing a new phenomenon in a number of T8 4' fluorescents: About a foot of the lamp glows orange at one end and sometimes flickers. It's usually...
There is an old dusk to dawn light on a building about a bloack from my house. It has an old bulb in it, at least 11 years old, probably older. Anyway, it...
What shape is the bulb, and does it have a clear end or all phosphored? Being at least 11 years old, it's not that old! Most 1990s mercs are junk, even being...
When I say at least 11 years old, that was about the time I became interested in streetlights, and noticed this bulb. It is completely phosfered with a round...

... Yes, that is what it is. The fixture is so high that it is hard to tell any specifics about it. [Non-text portions of this message have been removed]...
... I've been astonished by how long it can take the electric company to replace an out lamp, especially if it is in a remote location. There is an old NEMA...
Around here the utility used to have a "spotter" who drove around the city every night looking for cyclers or burnouts. But they got rid of this person in an...
All of our residential streets are merc. I reported one out on my street last summer to the city, it's still out. The area it covers is very dark as the street...
Man, still installing mercs with new poles these days??? A rare sight indeed! In one city here in California a new cul-de-sac with new homes was built, and NEW...
Dave I live just north of Detroit in St Clair Shores. I should add that the side street north of me was converted to HPS with the original poles. Also I don't...
NOTE: One thing about our city like many is the budget keeps getting smaller and smaller. Several municipal services have been cut in the last few years. No...

Hello all. I was wondering what voltage should I see at the screw base of a 175w MV under lamp load? I have one that doesn't get as bright as other 175w I've...
According to the data I have, the operating volts for a 175W lamp, measured at the lamp itself, is 130V for horizontal operation, 128V for vertical. Measure...
