Hey custom39,

Cool tubes... they kick ass.

Glass absorbs light... but, I would GUESS a very small percentage... go with the cool tube.

As to the bulbs, 600W vs 400W is a no-brainer... if $ isn't involved... go with the 600...

Bigger IS better. (unless you've got multiple smallers...)

Try a cool tube with a reflector behind it... that'll be cool... coooooool tubes! yeah!


Side-question::: does your name have to do with a '39 hotrod? Just curious...

Best,
