How to Identify your lamp Size & End Type:
Usually the lamp size is written on the lamp, there are a few different ways companies do this. Some examples include the following for a 71" Series Lamp ( Velocity F71 100 watt ) 71 being the size of the lamp. Another method is sometimes companies will write ( Super Sun HO ) a HO Generally means its a 71" Series and 100 watts but could also be a 59" Series lamp that's 80 watts. Please use the information provided below to identify your lamp.
THE MOST COMMON LAMP LENGTHS
F59 Lamps are 57 3/8" long when measured from metal cap to metal cap they are Bi-pin only
F71 Lamps are 69 3/8" long when measured from metal cap to metal cap they are Bi-pin only
F72 Lamps are 69 1/8" long when measured from metal cap to metal cap they are RDC only
F73 Lamps are 70 1/8" long when measured from metal cap to metal cap they are RDC only
F74 Lamps are 71 1/8" long when measured from metal cap to metal cap they are RDC only
F79 Lamps are 77 3/8" long when measured from metal cap to metal cap they are Bi-pin only
Besides actually having the wattage written on the lampend, some companies use different terms to describe the wattage of the lamp. Below is a list of most common ones used
HO or H.O. = 80, 100, 105, 120 watt lamps non reflector
RUVA = 80, 100, 105, 120 watt lamps with reflector
VHO or V.H.O = 140, 160, 180, 200 watt lamps non reflector
VHOR or V.H.O.R = 140, 160, 180, 200 watt lamps with reflector
VSR = 140, 160, 180, 200 watt lamps with reflector
REFLECTOR or NON-REFLECTOR
Lamps come in reflector and non reflector versions if your tan time on your bed is 20 minutes its a 99% chance its a non reflector lamp. There are a few ways to tell if you have reflector lamps usually its labeled RUVA, VHOR, VSR, or FR-. You can also tell by looking at the lamp 180 degrees of the tube will be white and the other 180 degrees will be transparent.
LAMP OUTPUTUVB/UVA ratio: I'm sure you have heard of 5.0, 6.5, 7.5, 8.0, 9.0, 10.0 lamps This is the most deceiving term in tanning what this number represents is the ratio of UVB output to UVA output, it actually has nothing to do with how much total output the lamps has. For example lets say we have 2 lamps Lamp A. 5.0 rating and lamp B. 5.0 rating now lets say lamp A. has a total UVA output of 30 mw/cm^3 and lamp B. has a total UVA output of 33 mw/cm^3 that would mean lamp A. total UVB output is 1.5 mw/cm^3 and lamp B. total UVB output is 1.65 mw/cm^3. Now to get the total output of a Lamp we need to add the UVA + UVB for lamp A we would have 30 + 1.5 giving us a total output of 31.5 mw/cm^3 for lamp B we would have 33 + 1.65 giving us a total output of 34.65 mw/cm^3. In Conclusion Lamp B is 10% stronger overall even though both lamps carry the same 5.0 Rating. See Graph Below For Visual Comparison.
Lamp Total UV Output LAMP A vs. Lamp B
Now that we understand that UVB to UVA percentage is just a ratio we will move on to what UVA & UVB are and how they affect the tanning process.
UVA-1: 340nm to 400nm wavelength
This is what actually gives you your tan. UVA Darkens the pigment in the melanin that the UVB light created.
UVA-2: 320nm to 340nm wavelength
This is photo aging light that makes your skin age prematurely most tanning lamps have a lot of this, we have filtered almost all of it out in our Tss - Bronzer line of lamps.
UVB: 280nm to 320nm wavelength
Stimulates melanin production, without UVB there would be no melanin for the UVA light to brown. UVB is also what makes you red, getting really red does not make you tan faster. Higher UVB lamps tend to burn you more than tan you.
WHAT RATIO TO USE:
Generally in a 100 watt lamp a 5.0 ratio will give your plenty of uvb for melanin production and plenty of UVA to darken the melanin. In a 160 watt lamp 2.0 is generally the desired ratio.
LAMP HOUR RATINGS ( THE TRUTH !!! )Everyone has the longest lasting, greatest of the great lamp right ? The truth is most lamps barely make it 600 hours, no two companies can generally agree on the way to rate lamp life. The general rule of thumb in the tanning industry is when your lamp output drops by 20% on a UV meter you change them. So we base our figures on this and only this when rating lamp life. 80% output is where we rate lamp end of life. And truth is we have only seen 4 Brands of lamps made that can achieve this. We have found most companies rating there lamps at 50% - 70% output for there end of life. So don't be fooled by all the hype. Another issue that arises quiet often is home tanning bed owners worried about longevity of a lamp, in all reality this is not at all important because once a tanning lamp is lit for the first time you only have 4-6 years to use it 5 on average. This is due to what we call phosphor decay. If you figure you use your bed 3 times a week for a year this is only 156 sessions a year at 20 minutes a session that is only 52 hours a year. 5 years that's 260 hours. There is however a catch to this also, many companies that sell cheap lamps do so by using very cheap phosphor which can decay much quicker 2-3 years. We developed the Golden Goddess Line specifically for this market of home users that's want a good phosphor that can last 5 years or 600 hours.
Lamp Output vs Hours of Use
TAN TIMES ( THE FACTS !!! )
Tan Times, here is another thing that can be deceiving no lamp has a specific tan time they usually have a range like a TSS - Bronzer F71-100 watt lamp has a range of 15-20 Minutes this is because in different equipment due to reflectors and lamp placement it can give different tan times. We always rate our lamps for what they generally go in.
