Found a HID ballast? Take a look here!

rjluna2:
TiCoune66, are you planning on posting the list of old ANSI Ballast code?

Vince:
Boy ... I should find them all. I think that only the ballast codes for mercury lamps changed. I know that H1 is the former H33 and H22, the former H39, but that's it, I don't know the others.

When I have a complete list, I'll post it here  ;)

FGS:
No need. I have the complete list. It's the same thread. Just moved it to the first page. (This is the second page.)

I am gonna make a new thread and post them there.

joe_347V:
Hmm I also wonder what are the old ANSI codes for MV lamps

So far I got

Wattage    Old ANSI Code     New ANSI Code100w   H4H38175wH22H39250wH5*H37400wH1H33700wH18**H351000w (130V arctube)H12***H341000w (250V arctube)H15*H36
Notes:

* Guesses made using the order code in old GE Bonusline lamps.

** From old lamp listings on eBay

*** From here on LG.

Mike:
Why did they change the ballast codes? I also wonder why they chose the numbers they did and why they're all out of order. :-\
