General Electric 250w Arcstream 742: Full Power

1 x General Electric 250w tubular quartz metal halide lamp in colour 742 at full power.

Quite a very nice neutral cool white colour from this lamp with no unpleasant yellow tint that other 4000k lamps have.
The run-up has a very nice pale blue colour before warming to it's final colour which is as good as Philips HPI+!
