Sunbed ballast tray

Sunbed ballast tray. These are 120 volt ballasts run off a 20 amp 240 / 120 circuit. This is well under 20 amps but the inductive kick from all them turning on at once will trip the breaker, so I added a 10 second time delay relay (upper right) for half of them.

Hmm I wouldn't think it would trip the breaker. Breakers have a trip-curve, meaning unless it's several times the rating of the breaker, there is a time delay before the breaker will open the circuit. Circuit breakers effectively are equivalent to time-delay fuses. But they do make breakers with different trip-curves for special uses, so perhaps this originally had a special breaker with an extended trip-curve? Seems like a time delay contactor is the simplest solution to the issue though! 13 ballasts in one enclosure is way cool looking! I bet there's a lot of buzzing going on?

To resist is to piss in the wind, anyone who does will end up smelling.

If this is under the bed where a person would lay, I can just imagine the thud one would feel from inductive kick when they are powered on

Dumb question, but could someone get burned if one of the lamps is reaching EOL? I know nothing about how a tanning bed
works, (pretty obvious with this question) but I do know that EOL lamps typically get hot at the bad end during EOL.

Interests
1. Motorcycles, Women, and Lighting (especially fluorescent)
2. Weighting/staying extremely athletic
3. Severe Thunderstorms of all kinds
4. Food and drinks. So gimme them bbq ribs
Yep
Lighting has been a passion of mine since I was born. I consider everyone on LG to be a friend

susukir122, the tanning bed itself is fitted with several cooling fans, effectively keeping the interior cavity where the person lays a comfortable temp. An open cathode failing lamp wouldn't even be noticeable, except for the flickering. There are tanning beds that also use 400w metal halide lamps literally inches from your face, they design the cooling systems of these beds so the user doesnt feel the heat

IDK, it would intermittently trip the breaker upon startup even though it was no where close to maximum load, the breaker is not a GFCI, and there obviously wasn't an electrical problem because it doesn't trip it now with the startup delay. If it was something like a bad ballast you'd think it would do it consistently even with a delay.

Sun lamps are typically replaced long before the cathodes fail, generally at around 1000 hours, because the U.V. output starts to degrade. A home user might keep them longer due to the expense of replacement (they're about $12 a pop even for cheap typical 5% lamps) but they'd still probably get replaced before the cathode fails.

You do feel the heat of the lamps, it's extremely relaxing laying down for a couple of minutes being warmed on all sides and the racket from the fans and ballasts muffling outside sounds. If a specific lamp failed even on the bottom you're separated by thick acrylic so I think that would help disperse the heat a bit if a specific lamp failed. Also you wouldn't use the thing if you saw one of the lamps wasn't working before you got in.

Between the UV exposure from the lamps and the potential EMF radiation from all these ballasts this doesn't exactly seem healthy...

Any machine is a smoke machine if you operate it wrong enough.

Looks like those are Valmont Electric Bonus Line magnetic ballasts.

There's actually quite a few sunbeds, even those made fairly recently that are fitted with 240 volt preheat ballasts, those imported from Europe. American made sunbeds tend to use 120 volt rapid start (although I'd imagine new ones use multi-volt electronic)

I occasionally service tanning beds and these older ballast cases with the magnetic gear weigh a ton and are a total pain to move when there are placed somewhere inaccessible, and need to be opened up and a ballast replaced.

The modern ones almost always use the Fulham Sunhorse ballasts (at least the makes/models I service) and weigh a tiny fraction of the magnetics.
