I've had the same question. There has to be a difference between
ETC Part#RT114 HPL 575/115X (Ushio Specs) Other
and
ETC Part#RT171 HPL 575/120X (Ushio Specs) Other
right?
ship? STEVETERRY?
Why does there HAVE to be a difference other than the obvious? You are looking at the difference right in the description of the lamp. They engineered the lamps to have peak performance at either 120V or 115V, the idea being that you match your lamps with the line voltage as Sean said. The other idea being that both lamps' peak performance will have the same output characteristics at different voltages. Though some people will buy the 120V version to put in 115V systems to eek a little bit more life out of them.I've had the same question. There has to be a difference between

That really depends on if you need the output, or if you are concerned about lamp life. The X version puts out less light at a lower color temp (more yellow), and the standard gives you more output at a higher (whiter) color temp.
