What the hell is Mug 6 glass?

I bet the old UB 818 used Uvisol 95 mixed with Type 320 Clear to yield 0.4% UVB.

you would be incorrect sir...

[solarmeter®]

What combination would be correct sir... ?

Meaning Home Depot 4mm single pane - $1.00 cut to size haha.

Yeah, wasn't it you & someone else arguing this with me on this very topic about 2 years ago on one of these sites?

it was MUG 6 with Sanalux clear

[solarmeter®]

OK... so whatever Sanalux is must block more UVB than the 326 glass. Or the chart is wrong. Or the bare bulbs had less UVB to start with.

ummmmmmmmmmmm
wasn't me, and wasn't this year, but...
What a tangled web we weave.

HEY you guys (and Bunz)... it was the famous Lief V. from QDM who clued me in about dimestore clear glass years ago. And I still believe him.

Take your UVB meters and check transmission through various expensive vs Lowes chunks and tell me what you get.

Will the dimestore stuff crack, shatter, solarize, or blow up before the real McCoy? Beats me. But I betcha there are plenty of old QDM's around with the el-cheapo glass... tempered of course! It ALL blocks some IR... depending on thickness as to how much.

Me Not Know Either.

I just LOVE our retro 2001 sig tags!!!!!!!!! Don't you? Slumming from Squawk lol.

Absolute collectors items.

[John]

Believe what you want, but there is no way in hell I would ever tell someone that, or even attempt to use stock Home Depot cut to size glass in any HP machine.

We once had a customer that called and complained about the output from his Supernova and after trying different lamps, voltages, and playing with the filter glasses we found out that he went to Home Depot and had acrylics cut rather than purchase UV acrylics...needless to say his home depot acrylics were hurting his UV transmission

Yeppers. Bruce S. said he gave me that because I didn't care to venture across the waters. I miss old Brucey. He had a flair for keeping things exciting. I wish I had of saved some of the "Pub" classics.

My husband owns a glass company. No way would I even think of putting his plexi or lexan in my beds. He did order some UV lexi once and would cut & bend to size.
Humm I need to check into that again. Might save a few $$ or not.

[solarmeter®]

I was NOT talking about plastic. GLASS only.

Only UVT acrylic transmits UV. Everything else blocks close to 100% of it.

On the other hand... clear glass is clear glass. It's wavelength cutoff pretty much just depends on thickness.

The Schott varieties, however, can "tune" the cuttoff based on the number (like 316, etc). The number is the half-power-point .... ie: 50% of 316nm transmits. Less below 316 and more above 316nm. Curves for WG glass on Schott site shows this.

I'm looking at getting a HP for this season. A Sportarredo rep told me their glass is better that MUG6 (of course.. he's a salesman). If so, what gives, and what is the difference between MUG6 and Sportarredo's glass?

[John]

Sportarredo glass is good, but sucks ass to change if it breaks. The glass they used is hand made & is all crazy, cracky looking. (Can't tell if it is broken until the bed is on) They are also shingled in the cassette, they have about 4-5 pcs per facial. Also there is no safety feature to this set up, which sucks since you can burn someones face off pretty quick.

oh yeah... the rep said the 4-5 pieces allow for expansion and contraction with heat, reducing the likeliness of breaking. any truth to this?

[John]

Yes, that is true. However they still break & there is no safety switch to shut off the lamp on each piece of glass.

Most HP units will have a safety switch built into the cassette or into the glass itself. This is very important to have & could save you from a lawsuit.
