Convoy T2 (LH351D 3500K) vs T3 (219B 3500K)



First 10 minutes:

The lowest mode (14500 battery). Left: T2, right: T3.:

The highest mode (14500 battery). Left: T2, right: T3.:

Convoy T2 is the stock 4 modes driver with LH351D 3500K.

Convoy T3 is the stock 13 modes driver with 219B 3500K.

Used tools:

  • Opple Light Master III – duv, cct, cri
  • Uni-T UT383 – for throw and lux measurements
  • Uni-T UT210E – to measure current at the tail
  • ceilingbounce app – runtimes

I don’t have reliable way to measure lumens, those are just number relative to each other.

It should be interpreted this way:

  • T2 LH351D 14500 has 189% of T3 219B 14500 brightness.
  • T2 LH351D AA has 115% of T3 219B AA brightness.

They aren’t comparable in any different way:

  • They don’t mean that output on different battery type is equal.
  • They don’t mean that output on 14500 is brighter by 74%.

So the T2 goes both dimmer and brighter? Sounds like the winner.
