I agree that UF-t50 may be a little overpriced, but I am still impressed it held up through more-than-demanding tests that the typical person wouldn’t put their lights through (on purpose) very often.
Drop and drag and crush tests are a true test of durability as well, and I can’t wait to see what Scaru discovered!!
UF T50
Hurry up scaru! I don’t like being in the dark! (pun intended) 
I got my hands on a chromebook to post from, so all the pictures are being uploaded to photobucket now.
Great! Can’t wait, good to see you back!
Ok, now that I have a computer to post from here the results are. :D
Here they are as I received them.
Since some people are curious about the reflector of the UF-T50 here it is.
First, I drop tested them. Over and over and over. I started with a 15 foot (approximate) drop onto grass.
Here the T50 is after a 15 foot drop, it was on when I dropped but when it hit the ground it turned off. It did the same thing with every drop.
The SC600 however stayed on when dropped. (It is peaking out from underneat a leaf here)
So far no damage to the lights, anodizing still intact. So why not drop them from 5 feet onto a stone patio?
Damn, they are both intact. 10 feet it is. :evil:
The SC600 is still on after a 10 foot drop onto stone, but the UF-T50 is off (as usual). Both are still functional, but the glass lens on the SC600 cracked. It is no longer waterproof, but other than that fully functional.
So this means both lights are functional, but the UF-T50 is ahead so far. Read on to find out how they do with an extended runtime on high.
I hooked both of them up to a power supply and ran them for slightly less than 3 hour on high non-stop. This is the test set up. They were both supplied with 4 volts, CV.
The SC600 seems to have some method of dimming in order to manage the heat. Here two pictures are: the first is on full brightness, the second is after two hours.
The UF-T50 however ran at full brightness the whole time. 
The SC600 peaked at 142 degrees Fahrenheit (43 Celsius) and the UF-T50 peaked at 189 degrees Fahrenheit (87.22). As I was watching the temperature rise I thought that surely they would both survive since they already survived at 200 degrees in the oven. Then the UF-T50 started to flicker, I decided to leave it running. After 1 minute of flickering it went in to a moonlight mode.
(For some reason the reflector looks textured in this photo) When I disconnected it from the power supply it turned off (since there was no power). I let it cool for around 2 hours and then put a battery in it to test it, it didn't turn on...
So to summarize, the UF-T50 is dead and the SC600 has a broken lens and a smashed lanyard ring. (Pictured below)
These are some crazy torturing! I don’t think I’ve come anywhere close to this madness in using my lights.
Madness? THIS IS BUDGETLIGHTFORUM!
The only light I have ever seen that took a drop test like that, was one that had a very thick rubber outer skin on the whole light. It would bounce, but it never would break. Also it had a plastic lens which never broke. Yes, I did a torture test with it, throwing it hard on the concrete several times... It felt very satisfying, except it wouldn't break, LOL. Maglites fall apart rather easily too.
Looks like it's going to be cheaper to buy two new lights than to buy replacement parts for these guys.
I have set aside an infirmary for the incoming patients.
All the talk about the ZL's being delicate flowers...what a crock of crap! That's some tough stuff!! I have new respect for the two I have now but I will NEVER put them through any of that stuff. :p
And both had been boiled at 212F. I guess the UF-T50 had had enough fun. Oh well. Thanks for your excellent work! This has definitely been eye opening. 
Looking forward to seeing if the SC600 can survive mkett39’s tests 
I will send that out on monday since I didn't get a chance to today.
That’s telling! One gets what one pays for?
Easy enough to put a new lens in that SC600, and its good as new
Awesome and entertaining work!
Nice work guys. Funniest competition I've heard off for along time. OL, no piking out now. The whole of BLF is going to be watching you wave your magic over these two lights so that they may be something they were never meant to be. Good luck.
I think the dimming of the SC600 after a while is the built-in timer in it. Using a stopwatch, I have tried it several times in my SC600. If started on TURBO mode, the light will step-down to HIGH after exactly 5min, 3 secs., or if a ‘tired’ cell is used, then it will step-down anytime below 5min.
A bit of glass is missing on the SC600, right?! It needs emergency care before mkett39’s bucket of oil! 
The T50 is dead, its lost already.
Let us treat our wounded! Please!

Yes in that second picture there is a piece of missing glass, when it cracked that part was no where to be found.
+100 We’re counting on you! But no pressure
