hello,

last week i bought three new radium 400's

i am running them on coralvue ballasts

one of them has turned very pink. Just wondering if this is normal or if i may have gotten a bad bulb.

here a few pics.

the pink is on the left

Have you got any ideas on this?

thanks,
 
Hi, I posted a message in one of your other threads about this. Make sure the nipple in the arc tube is pointing in the upward direction, between the 10 and 2 position. If the nipple is pointing in a horizontal, or downward position, the color will burn differently.
 
hello,

yep after using reeflux for so long i was aware that something like that could be the case. I positioned them up from the start.
