1: My suggestion of disposing of tailcaps, bezels, & battery doors when performing battery changes by throwing them into the garden with all those hungry, hungry praying mantids, stomping on them with old or used bowling/baseball/golf shoes, chucking them into the garbage can (dustbin), flushing them away, throwing them into an open-pit cobalt or zinc mine, throwing them into construction sites so that heavy machinery will run over & flatten them, kicking them into the forest or the weeds so skunks or squirrels pee on them, etc. is *NOT* to be followed; just set them aside. Some people have not read the directions I publish saying you should stop at once and just set the part aside, and have thrown tailcaps, bezels, & battery doors in the garbage can, out windows, flushed them away, etc. and then became all pissed off when they could no longer reassemble the flashlight.
I cannot be held responsible for battery doors, tailcaps, bezels, etc. that become damaged, destroyed, or lost because you failed to read the "O WAIT, YOU'LL NEED THAT!!!" or "O WAIT, THAT'S THE GOOD PART!!!" statement before disposing of that part of the flashlight.

2: Test circuitry used in many of these tests was not originally intended for such use. I would recommend you use a battery-powered supply unless you are willing to face the wrath of 110-240VAC line voltage. Only the experienced should use line-powered equipment such as power supplies. Note that line voltage is fatal to LEDs as well as to you.

3: Some LEDs generate optical energies in excess of what human and animal eyes were designed to accomodate. If you must stare into a really bright LED, do so in a room that is already bright or in direct sunlight so that your pupils are contracted to their smallest possible aperture size; and only do so for a few seconds maximum and allow your eye to recover for at least five minutes before repeating this stunt. Never, ever use a magnifiying lens of any strength to observe the insides of any high-brightness type LED while it is operating anywhere near its rated power. If you wish to observe in this manner, drive the LED with only 1 mA or less; you can then safely and easily observe the much dimmer chip if you do it this way.
Never, ever stick a live high-brightness type LED directly up to any person's or animal's eye. White canes might work for people, but they just don't work for cats & dogs. If for some reason you feel the need to shoot your pet (or sibling) with one of the ultra-bright LEDs, please keep it at least 1 foot (or greater) from their eyes.

4: Some LEDs are especially sensitive to even tiny amounts of static charge. With the newer gallium-nitride types, it is recommended you use a wrist strap or anti-static gloves when handling the bare LEDs. Once they are connected in a properly grounded ciruit, this danger is minimized.
When possible, store this kind of LED in an anti-static bag, or stick them into conductive foam before putting them away. If you don't have an anti-static bag or conductive foam, household kitchen aluminum foil (Reynolds Wrap or similar) may be used.

5: LEDs which are severely abused have been known to strike back at their tormenters by exploding rather violently, shooting pieces of broken epoxy at high speeds which can cause eye injury.

6: Tests of LEDs on this website were conducted with samples which may be small in number (sometimes as few as one) or with LEDs of unknown pedigree. Your results may and probably will vary, at least to some degree. No guarantees are offered, nor do you have any recourse if you buy LEDs based strictly on the information presented here and then later find them unsuitable.

7: If you cannibalize obsolete equipment for its LEDs, you alone assume all danger of electric shock or property damage should that equipment be disassembled while energized. Some equipment also has capacitors or other components which retain a residual charge even after disconnection from the primary power source. Such equipment may include (but isn't limited to) devices like lasers, photocopy machines & laser printers, toilet seat heaters, photoflash heads or guns, disposable cameras, computer printers or other peripherals, television sets, computer monitors, medical equipment, automatic urinator flushers, household appliances, pool filters, heated bidets, scrapped avionics, motorized adjustable beds, microwave ovens, currency handling equipment, correctional facility equipment, and industrial controls & machinery.

8: Just be careful, but have fun, ok? Remember, we are not responsible if you blow the piss out of your garage, burn out your remaining eye with a laser you modified using information you found here, start the family Christmas tree on fire, blow the legs off your favorite chair, blow a toilet off the wall, burn yourself with a soldering iron, shear your head clean off your shoulders attempting to create or recreate some bizarre experiment or other found here or linked to from here, or cause any other damage to property or persons costing more than a minute or so of your time to repair or replace.
Although it's true that a mistreated T13/4 LED won't do much if you flush it down the can or blow it up inside a plastic pop bottle, with some of these newer super duper models, one can never be too careful.

9: All product names are trademarks/trademarked by their respective owners. Except for electronic advertising materials & banners, trademarked product names and logos are used without permission or compensation for the purpose of product comparisons and the dissemination of information.
All brands of LEDs and LED products are treated (or mistreated) equally.

10: Discrimination is not tolerated here. E-mails are answered and products are evaluated without regard to the source, so long as I can read such e-mail or any documentation that comes with potential test samples. (Products that come with foreign language only documentation will be evaluated like any other, but it does help to know a little about the product first). :)

I do not discriminate based on race, religious or political affiliation, marital status, sexual orientation, physical or mental disability, education or lack thereof, financial status, bathroom habits, or other traits.
Please note that I read & understand only English, so please use English or have your native language translated to it if you write me.

11: LEDs or other property that is sold and then returned "refused" or "unclaimed" by the postal service is held for 60 days only, after which time it may be placed back into inventory and re-sold to somebody else with no further recourse by the original recipient unless that person contacts me within the 60 day period. (Peter S., your 60 days are up, and somebody else bought your LEDs!)

12: I am always looking for samples to test for this web page. If you have some LEDs you wish to see on here, or have an excess of some you just aren't going to use, please feel free to wing them my way. They will usually show up on the appropriate page, and if you're really lucky, you may even see them in the museum!

14: Psychotectic treatments (or psychotectic therapy) and reflection therapy (regarding my need to beat poor, innocent, defenseless, helpless, cute & loveable little flashlights against concrete) - it's just part of my job are totally fictitious terms terms related to mental health treatments.
"Psychotectic treatments" (or psychotectic therapy) is from the Star Trek: TNG episode "The Outcast".
"Reflection therapy" is from the Star Trek: TNG episode "Frame of Mind".

15: WARNING! Neither myself, nor anybody associated with any outside links to this page are liable if you screw things up while experimenting with lasers or performing modifications to them as shown on this website and end up setting your favourite chair on fire, shooting down your cat, blinding yourself, vapourizing a toilet bowl, setting off your hidden cache of illegal fireworks, or injuring somebody as a result!
Nor are we to be held responsible for any property damage, traffic accidents, weapons fire, or other damages resulting from your use or misuse of this information. PLEASE BE RESPONSIBLE! Observe all normal laser precautions for a CDRH Class IIIB instrument.
