Shadow's TC350 fills the slot in their lineup as the only dedicated 1x18650 light (the GF1 is a hybrid w/shorty tube):

It utilizes the same UI as its brethren except that it features an extra forward mechanical clicky tail-switch in addition to the electronic side-switch (like on the TC500 and JM07). This is a very popular and thus crowded segment, let's see how it holds up to its peers...

VIDEO SUMMARY
Here is a complete video summary of the TC350 while while I work on fleshing out this review:

SIZE / HANDLING


L to R: Redilast 3400 | XENO S3A | Shadow GF1 w/18650 tube | Sunwayman T20C | Shadow TC350 | XTAR TZ20 | ThruNite TN11S | Crelant V9-T6 | Niwalker NWK600 N1 | Nitecore P25

The TC350 is one of the more compact 1x18650-sized lights despite it's tail-switch. It fits very well in my medium-sized hand in either over/under-hand grip:

RUNTIME & OUTPUT
The relevant battery stats are provided above each runtime graph along with:
- Voltage of the battery at the start and end of the test
- Current draw
- Actual runtime using ANSI FL1 (first in HR and then in M so for the RL3400 on High, read this as 1.7hrs or 101min)
- As of May 2012: Lumens measured on my PVC LMD @ 30 seconds
- Also for Turbo, captured the temperature: ambient, the head/fins at start and the max it reached (fan was used for all bats)


Max output measured @ 30 seconds was 736lms w/the RediLast 3400 (note: although I calibrate my PVC LMD before each runtime/lumens testing, the ambient temp will also cause deviations in readings).

After a slight dip, the TC350 initially runs decently regulated for a short duration before attempting a mild boost to stay in regulation and then going into a drawn out decline when the cells can no longer maintain the necessary current draw. The low-voltage warning kicks in at the very end of the run thus it's important to charge the cells immediately at this point since it's already very depleted.
