As I lazily watched the New Year's Rockin' Eve from New York last night, I just happened to notice that one of the pair of streetlights above the stage, where...
I would be interested in a picture of that ballast. The ones that make the 'clicking' noise while trying to start the lamp are the 'old' design that I'm...
While it's true that I've probably spent more than $33 on parts in my electronic-ballast experiments, I find it much more fun to try and build something out of...

I might be buying a Form 79 soon and I'm considering lamping it using a 55w/65w CFL. What do you think? What color range would you use? I've also noticed some...
It depends on what color light you want to emulate. For a clear merc look for a 6500K CFL. For a Deluxe White merc look for a 4100K CFL. Both lamps will...

... A couple years ago I converted a couple of 50W HPS wall packs at my mom's house with 15W daylight CFLs. I was very pleased with the results and have not...
Thanks for the reply James. I'm really beginning to like the CFLs more and more. In fact most of the heavily used lights in my home are now CFL. These are...
Exactly why I asked as I couldn't see why an on/off relay type photocell would matter. Anyhow I'll probably use one in the 4K CFL. Brian ... merc look for a...
Interesting. That's very similar to the ones I used to have, obviously the half bridge, the inductor, and the starting circuit are the same, but it looks like...

There is something else you might want to think about, and that is the use of a CFL in a fully enclosed fixture. Many CFLs, especially the higher wattage...

Yup, the mercury ballasts are slated to go effective January 1, 2008. I heard that mercury vapor lamps will finally be discontinued in Europe this year or so....
They are no better than the Philips Alto T-8 lamps. In fact the GE Ecolux is MUCH worse. I have seen LARGE numbers of failed GE Ecolux T-8s in supermarkets,...
