Small light with superb quality, great interface and with intergrated diffuser. Strong tail magnet and easy to use headband. I totally recommend it.

I was in the market for a AA headlight to replace the 18650 one that I have in my car. Although run-time is significantly less I wanted to standardize on Lithium primaries and/or NiMh for all my car lights (each vehicle has a headlight and 2 AA flashlight). Since the E03H was on clearance I decided to try it out.
The light appears to be well constructed and the threads are square cut and came clean and well lubed. The body knurling is diamond pattern and feels good in my hand. No complaints at all about the fit and finish.
The tail cap contains a magnet which is strong enough to hold the light in any position without fear of falling off.
The head-strap is stiff compared to most that I have but holds the flashlight well and should prove satisfactory in use. The pocket clip must be taken off in order to use the head-strap.
Testing shows that step-down from turbo to high happens after about 3 minutes. I don't have an integrating sphere but using a lux app on my phone indicates that the output is fairly well regulated (maintains the same brightness level on a mode rather than dropping as the battery is emptied).
A single press on the switch starts the flashlight in moonlight while a long press starts it in the last mode used. Each click then cycles the light up. From moonlight the cycle is low/Mid/Hi/Mid/Low. From a long press the cycle is last mode used, etc.
A double click from off will turn the light on in turbo and clicking the switch will cycle through the strobe modes. I would have preferred that turbo be part of the normal modes and accessed by a double click while the light is on.
The switch is a bit too recessed for me and a double click to access turbo was harder to perform than it should be.
The beam pattern is good with no irregularities. Diffusers come with the light but I would use diffuser film instead. Tint was fairly neutral with no hint of green.
Without an integrating sphere I have no way to measure the output but the stated output seems reasonable compared to other lights I have.
I would have given the E03H a 5 but the double click to turbo putting it into the strobe group dropped it a star for me.

Hi. My name is Dave
On a scale of 1 to 10 I rate this a 100.
I am going to order another one.
I have been out side for the last two and a half ours putting a Ham Radio antenna up in the dark and the light did not dim down at all.
I love the different settings to choose from.
If you order one don't get impatient 'cause it takes a little time
to get to your place but worth the wait.

P.S. I wanted it because it only takes one battery.

I purchased this after owning the E03 for some time. The Nichia 219C is one of the nicest LED's available today. The tint and color rendition make it hard to go back to other lights.
The beam is large enough for using the headlight for close up work, and if you use the included diffuser, the beam is quite floody.
The magnet andthe head band work quite well.
If you are afraid of the light turning on in your pocket, loosen the tail cap about 1/4 to 1/2 turn.
This light, at this price point is an excellent value.

I bought this light for use at work and to light the way home at night. It is usually clipped in my shirt pocket or belt and I have not used the headband. The size is great and it falls comfortably into my trouser pocket ready for when I need it
The CREE emitter throws a consistent beam across the area and the color is good. Battery life is good with rechargeable AA cells.
CON: To turn on the light to it's last mode requires a long press. A light press however, will turn the light on in moonlight mode. Since I carry the light in a trouser pocket, it turns on accidentally sometimes. In my opinion it should only turn on with a long press. This is the reason for only 4 stars. Otherwise it would be a 5 star product.

I have been using this torch for the past month on early morning dog walks. Overall I like the design of Manker head lamps and own the aaa version as well.
The pros: very well made. mode spacing is good, not too heavy, good run times with large capacity AA NIMH cells. Beam pattern is to my liking for hiking and trail running at night. I like the color with the nichia.
Cons: the strap and holder for the torch are not well made and need to be wider. I have placed torch in zebralight headband so they wont bounce too much.
Overall buy this torch.
All prices are in USD.
