Cheetahs!

[MsHotTan]

Anyone use these 10 minute lamps? Good or bad comments on them?

[Brian Oshman]

Junk. B burners.

[MsHotTan]

I just bought 64 of them because they were highly recommended.

By who... an orange tanorexic? An ex-Panther salesman.

Geeeeze.

[stan@sunsys]

For people that like Hi-Tans, these are a good alternative.

By the person trying to sell them to her....surprise.

[supplyguy]

Light you up like a cristmas tree!

[supplyguy]

christmas even!

[hoptan]

We had these lamps - too strong for too many people - we received so many complaints from people frying

[T-Bros Tan]

We have had people like them alot. We actually put people in them for 15 minutes and they want to go longer!

[solarmeter®]

You're doomed.

[T-Bros Tan]

What bulbs are stronger - the Cheetahs or Interelectric Panthers?

[lampman]

cheetahs have more bite and do not drop as fast. remember it is not the amount of uvb but where it is in the spectrum.

[stan@sunsys]

The AMOUNT of UVB is much more meaningful than UVB%. All wavelenghts in the spectrum < 298 nm are more or less equally effective in producing erythema. The effecitvity of UVB between 300 nm and 320nm decreases by 2 - 3 factors of 10 in both erythema and melanogenesis, so shifting and peaking of spectral irradiances within those wavelengths will make a difference.

However, since the spectral character of UVB phosphors is mainly split in two groups of "traditional" and "new era" lamps, it is still the amount of UVB that mostly determines how redenning they are going to be. So saying the amount of UVB doesn't matter is misleading.

Or are you just trying to explain that it is not the UVB%, but the amount that matters, since the UVB% is only relative to the amount of UVA. Which is also true, and is the basic mistake that most people make.

On the other hand, for a given manufacturer, and pretty much for tanning lamps in general, higher UVB% usually means more UVB irradiance than lower UVB% lamps, at least, within a given lamp configuration of wattage and reflectors.

[W8INLINE]

So now, who will make it standard procedure for all manufacturers of lamps to show total UVA output, %b for the a, and the wavelength of the b?

[lampman]

Was trying to say all that in a short sentence. The same maker may have lamps with more uvb in % and total but positioned closer to the 320 mark. The lamp has "more" total uvb% and more uvb but the tanning time is longer than a lamp with spikes in the lower band areas. Some of these lamps like a philips pro-S are 4.8% but have a tanning time longer than a standard velocity or goldarium type. Another example is the Hi tan lamp. It has something like 4.7% uvb but has a time that is 2.5 times shorter than the above mentioned pro-S. Sol glass is another example lots of A in the 360nm but a blip down low than makes the lamp strong or shortens the exposure. Saying that the same manufacturer can use UVB% to determine exposure time is mostly correct when comparing to other lamps made by the same company, but not always true. The pro-S is a philips lamp and has a longer tanning time than the swift lamp. The swift has 3.3%. The philips advantage lamp is about 5.7% and is 18-20 minutes (100W) The philips advantage max lamp is about 5.0% and is close to 10 minutes (100W). They just moved the uvb down some
All I was really trying to say was that the % of uvb is not a good way to determine exposure times and was trying to get away with a simple note

[stan@sunsys]

LOL, yes, I understand completely about TRYING to get away with a short explanation. God knows I have no idea how to do it.

[W8INLINE]

so if you compare 2 lamps by the same man. with the same reading on uva and 3% b but one is on the upper spectrum of b while the other on the lower, which one will tan better?

[solarmeter®]

The one on the lower spectrum of B.... ie New Era vs Old Era.

It will also have less UVA2 (320-340nm) photoaging rays.... and UVA peaking near 365nm like natural sun 365-400nm. Old era peaks at 350nm and falls toward zero close to 400nm. They both have some visible spikes at 405 and 435nm which also tan a little.

Some skin types however will still prefer old era.... including the gotta burn before you can tan mindset. The UVA2 acts like more UVB.... so skin types 3.5-4+ with full tan (or orange) skin may actually need that to "see" any results.

[MsHotTan]

Update! Best lamp I've ever used and everyone agrees. If they are a first time tanner or light skinned, I do not allow them in those beds at all but for the person trying to achieve a better result above their base tan is LOVING these suckers. I will purchase them again in the future.
