[Review] XTAR T1 and T1-UV || Keychain lights with secondary RGB and UV emitters

The flashlights were sent to me by XTAR for review.

Here's the products' links: XTAR T1 | XTAR T1UV

The XTAR T1 and T1-UV are the latest two additions in XTAR's keychain flashlight lineup.
The flashlights are delivered in a neat little tin can.

Other than the keychain lights, the package also includes the following accessories:

  • USB-C charging cable.
  • Keyring.
  • User manual.

The T1 comes in flat black color, while the T1-UV comes in dark grey.

The keychain lights follow a square design and are e-switch operated.

Both models utilize a TIR lens along with a Cree XP-G3 emitter.

The head can be taken apart granting access to its internal components.

For stabilization purposes, the TIR lens is seated into a conical copper piece.

Despite using the exact same body, the emitter boards used by the T1 and T1-UV are different.
Left:T1, Right: T1-UV


As an added bonus, both keychain lights come with additional secondary emitters mounted on their side.
The T1 makes use of 1 x RGB and 1 x UV emitter.

While, the T1-UV utilizes 3 x UV emitters.

Being advertised as a keychain light, the XTAR has integrated a metal loop in the rear of the light.

The flashlights are rechargeable via a USB-C interface.
The charging slot is secured via a rubber flap.


Once plugged in, the indicator LED incorporated into the e-switch shines up to indicate the charging's state.
Red: charging, Green: full.

While charging, I recorded a maximum of of 0.2A of input current (1W).


Here's some picture while utilizing the Red, Green, Blue and UV emitters of the XTAR T1.


And a photo of the T1-UV using its 3 x UV emitters.

User Interface

Due to their different emitter setup, the T1 and T1-UV use a slightly different UI.

Turn on: Single press.
Turn off: Long press (1.5sec).
Mode cycle: Single press

  • XTAR T1: (Moonlight > Low > Mid > High > Strobe)
  • XTAR T1-UV: (Moonlight > Low > Mid > High > Turbo)

Momentary Turbo: Long press while off.
RGB (T1): Double press to enter, single press to cycle ( Red > Green > Blue > Police Strobe > RGB Sequence > Red Signal ).
UV (T1): Triple press.
UV (T1-UV): Double press.

Both models come with mode memory and LVP.

Output Measurements

Here's my output measurements for the XTAR T1.

As can be seen, the T1 is able to push more than 500 lumens while in Turbo at turn-on. Pretty impressive for a keychain light.
The mode spacing is excellent and the manufacturer's output numbers are actually very accurate. 

And here's my measurements for the XTAR T1-UV.

I found the T1-UV's mode spacing very strange. According to the manufacturer,
I should be observing results similar to the XTAR T1, but in my case the results are quite different.

It's possible that I've received an early engineering sample of the T1-UV as I was sent the flashlight before it was even announced officially.
Just to be sure, I'll make sure to contact the manufacturer to get some clarifications in the subject and I'll definitely update this thread laughing

Does the T1-UV work with a USB-C PD charger? I.e. USB-C to USB-C.

I tried a Google Pixel USB-C PD charger with a T1 and it didn’t charge. It charged with a USB-C QC charger.

i have a T-1, and the only complaint
is that the battery does not stay
charged very long.

today, it would not work.
charged it and all is good.
it had not been used for 22 days.
it had a full charge back then.

well, a very minor annoyance
is the USB-C has a tight connection
to the flashlight. i have to really push
harder than i like to get it fully inserted.
