Since I'm here, I might offer any help I can give with questions on lamps. I'm kind of rated as an expert on the question of them in the professional world (might have glimpsed a part of that in an earlier posting.)

My current function at work is to fix gear, train people in wiring stuff and lighting in general and to buy equipment especially lamps. (Before that, I was a Master Carpenter, TD and a Rigger.) I average buying about $1,000.00 per day in lamp purchases of all types and that's conservitave. I'm also writing a book on lamps and the differences between not only types but brands of them, along the lines of the Photometrics Handbook in usefulness - (kind of a Bible for the lighting design profession.)

Anyone who has interests or questions might post here about them. I don't sell them to people, just advise on them. Good thing to learn about if lighting is your desired prosession much less about general lamps.

Here is a extremly small example on HPL lamps on the market of my far in the future's book appendix: (Note the last number is for hours in life.) I use such a table (and it looks much better in table format,) at work every day in choosing what's the best lamp for a fixture or what other versions are available.

My current function at work is to fix gear, train people in wiring stuff and lighting in general and to buy equipment especially lamps. (Before that, I was a Master Carpenter, TD and a Rigger.) I average buying about $1,000.00 per day in lamp purchases of all types and that's conservitave. I'm also writing a book on lamps and the differences between not only types but brands of them, along the lines of the Photometrics Handbook in usefulness - (kind of a Bible for the lighting design profession.)
