hey kids

which way should the nipple face on these 20k xms. Another question, if my bulbs are cooled down completely whats a save way to wipe off the salt splatter.

thanks to all

In General, you want the nipple to face anyway but down. This is so that the mercury doesn't collect in the nipple.
Once the bulb is completely cooled down, a damp cloth would be fine to wipe the salt off the bulbs, but just make sure not to touch it with your hands and also let the bulbs dry off before restarting.

for stubborn salt, try a paper towel with vinegar on it. that should dissolve just about any crud you have. also good on reflectors.
