Is it dangerous to tan when a ballast is out? How do I change the ballast? Tanning bed?

After researching I'm to the conclusion that I have a bad ballast. The tanning bed worked fine 2 days ago.. then I get it in my home and all setup, and 4 bulbs (which work fine when moved around) in a row won't turn on. Well, can I tan in it anyways. How do I figure out what ballast I need to order.. and about how much do they cost? and how do I change it? Also.. is there a way to look at it and double-check that that's the problem. eg. when I fuse is blown you can tell.. will there be a visual different between a working ballast and a non-working ballast?Is it dangerous to tan when a ballast is out?

No light, no tanning.

If it's a 'U.L. listed' unit it will be safe enough to use

with only some of the lamps working, but better to

fix it.

Ballasts do not fail often. I'd suspect something else.

If it's been moved, those lamps may just be loose in their holders.

Try twisting them slightly to re-seat the pins in the holders.

If it's an older unit. there might be little cylindrical 'starters' as well.

Make sure that they're seated in their holders.

Ballasts do not always show exterior signs of failure.

You can look for scorching, that would be one, but it doesn't

always show.

Look carefully for loose connections.

(Power disconnected, not just switched off, while you're 'in there'.)

Unless you're confident of your ability to make safe

wiring connections, I don't recommend that you try

to change a ballast.Is it dangerous to tan when a ballast is out? How do I change the ballast? Tanning bed?
*Is it dangerous? well if you don`t die of skin cancer under your lights it sounds like you may just electrocute yourself first.
