TW4 LED lights

Does anybody have any idea of how many of these were "assembled"??? Sorry for the cryptic title but probably only owners will reply. Thanks smokin

Did TW do something to designate them as "official" TW4s? I thought they were just L4s with E1* bodies.

The "real" TW4s were handpicked for their low forward voltage, or at least their apparent ability to run at decent brightness on a single primary, or in regulation on a R123(I'm sure they weren't actually disassembled to check the individual LEDs).
Mine ran in full regulation until the battery protection kicked in on a R123. Something like half an hour on the old Battery Station protected cells, as I recall. Robocop here has had it for the last few years, and still uses it on a Vital Gear one cell body.

TW = Tactical Warehouse, a dealer that discovered the combo. I have no idea how many they sold but suspect that individuals still are attempting to find the magic combo of a KL4 head that will run for a very long time on a single cell body (originally a primary CR123 cell).
I personally went through a few heads to get my 2 TW4's and long ago modded one with a Cree.
Mine run for 5+ hrs on a primary cell.

Is that the new 120 Lumen KL4? Running on a primary the light is pretty dim, with an RCR you get almost full output, how do you get 5 hr runtime though on a single primary?

I do not believe it is the "new" KL4s but the older versions. how they operate so long I do believe is through that hand selection process TW went through to assure great performance with the single cell body. Mine goes for 6+ hours before dropping into regulation mode. Thanks for the replys , all info is helpful smokin

There is a thread about TW4 lights in the Flashlight Collecting section that has been running for quite a while.

Thanks for the reminder link, I now know I have the 100 lumen head!! My curiosity was sparked by just how long I have been using the same battery(battery station) I am at my daughters home following triple bypass surgery and have been here since march, and am still on the same battery since arriving, and it is still amazingly bright. Thanks to all respondents for all the excellent info and links.

Hope all is well with the heart overhaul.

Get well soon so you can get back to collecting lights.

thank you and yes I am feeling somewhat better but the surgery sites are no walk in the park to heal up had to go back in VA hosp for a case of cellulitis (not the same as cellulite) LOL it is a subdermal infection that trashes your energy reserves big time and requires massive antibacterial IVs and pills at home once released
