Tanning beds get lots of use during the winter months, but often don’t get so much use during the summer. After many uses, tanning bed bulbs will gradually lose their effectiveness. Even though they still light up, they won’t be as efficient at producing that luxurious tan.

In this article, we’ll look in particular at tanning bed bulbs. We will discuss how to test tanning bed bulbs, and we’ll go over everything you need to know to determine if you need to replace your bulbs.

Whether you’re a tanning salon owner, or you have a sunbed for home use, we’ve got you covered!

Quick intro: Know your bulbs!

Wolff Tanning Bed Bulbs

Before we get started, we’d like to limit some of the confusion that abounds when it comes to tanning bed light bulbs. Both in this article and in the industry, “tanning bed light bulb” and “tanning bed lamp” mean the same thing. The terms will be used interchangeably in this guide.

Even though “tanning bed bulbs” seems to be a more popular choice, both options are equally valid and you will find that at a lot of stores and a lot of online discussions, they mention ”tanning bed lamps”. 

Rest assured, it is one and the same thing. You do not know anything more about your tanning beds than you already do and what is contained in this guide.

For reference we’ve put together a guide of the best tanning bed bulbs should you determine you need new lamps.


Bi Pin and RDC Tanning Bed Lamps

You’ll find two types of tanning bulbs that are commonly available. While newer beds tend to use bi-pin bulbs, you may come across some old beds that are still equipped with RDC bulbs. Take a look at your bulbs to get a better idea of the type that is installed in your tanning bed.

This is what a Bi-Pin bulb looks like:

And this is what an RDC bulb looks like:

In general, most sizes come in either bi-pin or RDC and not both.

Tanning Bed Bulb Sizes

There are a few different sizes of tanning lamps. Some of the sizes that you’ll see most frequently are the F71, F73, and F59 varieties. “F” means “fluorescent” in the name, and the number is used to represent the bulb’s nominal length.

If you’re looking to replace your bulbs, obviously you need to stick the same size bulbs.

How long do sunbed lamps last?

The manufacturer sets the estimated amount of time the lamps will last. They measure this time in hours of use. This number usually ranges between 1000 and 2000 hours. Effectiveness, however, reduces significantly sooner than that. 

By 500 hours, most lamps have reached as low as 50% of their original intensity.

Most salons choose to replace their lamps at this point. If you have competition in your area, it is difficult not to follow along those lines since you will be providing an inferior service from then on.

Customers will be able to tell!

If you’re using your bed for home use, you may be able to stretch it out a little longer than that. But you may start to notice that your tanning bed is giving somewhat uneven tanning results.

Never partially replace tanning bed bulbs!

That one is really important. When it is replacement time, you need to replace all the lamps. Some people think that they can find just the faulty ones and substitute those. It does not work that way, unfortunately. 

Since tanning lamps are installed together from the manufacturer, and they have predetermined life expectancy, they go bad simultaneously. 

In addition, you will never be able to keep track of when the lamps need replacement if you are changing only a few here and there from time to time.

How do you know when your tanning bed needs new bulbs?

There are three signs to look out for when the time comes to replace the tanning bulbs in your tanning bed:

  1. Use your tanning beds from time to time. If you notice that the same effect you had at 10 minutes of use seems to be happening more towards the 15-minute mark, then that is a solid clue that your lamps need replacement.
  2. If you see lamps flickering, the bulbs are long overdue. Tanning effects reduce long before the lamps approach the end of their physical lives.
  3. If the tanning bed is used in a salon and a year has definitely passed since you last replaced the bulbs, it is time to do it again.  Bulbs in-home tanning beds, on the contrary, last around three to four years.

It is also advisable to keep track of when you installed new lamps and look out for the 500-hour mark. That would be the most definite reason to replace the lamps.

You can buy a small timer and keep it next to the bed, and start it every time you operate the device- with no resets, of course!

Tanning Bed Bulb FAQ

How do I know what bulbs to buy for my tanning bed?

Check your previous bulbs. Look for a model type in the form of Fxx, where the “xx” is two numbers. You can also contact the bed manufacturer.

I’ve just bought a second-hand sunbed on eBay, and I don’t know if it needs new tubes.

Most likely, it does. If it is priced low, it will need new lamps. The most expensive component of the bed is efficient bulbs, hence the low price.

Can I increase my wattage?

No, you cannot. If your bed has 100w sunbed tubes like these Wolff tubes, then you must stick to 100w.

Why do I have to replace my sunbed tubes if they still light up?

This is because tanning bed lights will still be still be able to produce light but will become much less efficient at helping you tan about halfway through their lifespan. If you want your tanning bed to actually work, you’ll have to replace the bulbs frequently.

Conclusion

Most people want to tan fast in a tanning bed. If your bulbs aren’t working right, well, you’ll be tanning slowly, if at all.

Knowing when it is time to change the bulbs in your tanning bed can seem tricky at first. That is what our guide on how to test tanning bed bulbs is here for!

It is a three steps process. Look out for signs that your bulbs are starting to lose efficiency. Once you replace them, keep track of operating hours. Follow the “no partial replacements” rule.

Good luck, and keep that dark tan going!
