DiscontinuedManker no longer makes this light; what dealers have left is the last of it. Its current replacement is Manker E03H III.

Manker's E03H II was a compact right-angle AA headlamp with a Nichia 519A emitter and a magnetic tail, taking either standard AA cells or 14500s. The E03H III is the maker's replacement.

Beam profile

Balanced, about 27° wide. A usable hotspot with enough spill to see around it.

Estimated from 600 lm ÷ 3,500 cd — how this works

What owners report

Manker E03H II/4 sources reviewed

A small AA right-angle light with an SST-20, 84 m of throw and IPX8 water resistance, in a Type III hard-anodised body. Reviewers call the build quality really nice and the light easy to handle, and one described it as a favourite little light. An improvement over its predecessor is that it accepts button-top 14500 cells.

There are two safety-relevant gaps worth knowing. The NW version has no built-in thermal protection, and the CW version lacks low-voltage protection — so with the CW you should use a protected cell to avoid over-discharge. The CW also has no charging port. And reviewers doubt it can reach and hold 360 lumens for more than a few seconds on a single AA, which is the realistic expectation to set.

Consistently praised

Right-angle body in a genuinely small AA format
SST-20 with 84 m of throw for the size
IPX8 — submersible beyond a metre for a prolonged period
Type III hard-anodised anti-abrasive coating
Accepts button-top 14500 cells, unlike its predecessor

Common complaints

The NW version has no built-in thermal protection
The CW version lacks low-voltage protection — use a protected cell
The CW version has no charging port
Unlikely to hold 360 lumens for more than a few seconds on AA
Variants differ in ways the listings don't make obvious

Questions people ask

Which version should I buy?: Check carefully — the NW and CW versions differ in protection features. The CW lacks low-voltage protection and a charging port, so if you buy that one, use a protected cell.
Is the lack of thermal protection a problem?: On the NW version it means nothing stops the light running hot if you leave it on high. In a body this small that's a real consideration — use higher modes in bursts.
Can it run 14500?: Yes, and unlike the previous generation it takes button-top cells. That gives noticeably more output than a AA.
Does it really do 360 lumens?: Not for long on a single AA — reviewers doubt it can sustain that beyond a few seconds. On 14500 the figures are more achievable.
