Since I havent seen a comparison on here before I thought a quick note comparing the Alpkit Gamma and Manta headtorches may be of interest.
The Gamma's been around for a while now (3? 4 years? more?); The Manta Ive only seen this year. Im comparing a 2011 Gamma with a 2013 Manta.
TBH not much point with beam shots as a) I dont have a suitable camera to hand and b) it's not really about the beam at this level but the usability.
(on posting their site is borked, too much bandwidth gorging been done this xmas by the look of it)
On paper, £15 each:
On the scales:
so bang on.
As for brightness, there's naff all between them. Really, nothing. The Manta was a little yellower in colour but you'd only notice it next to a bluer LED and that difference would be just down to bins.
Both have an identical beam pattern (with manta on fully focussed), and no discernible difference between them in light intensity at 5yds or indeed up to 10yds.
So the main differences are the obvious ones:
- Manta focusable beam.
Both beams at 5yds give a c.2yd spread. If the Manta is "zoomed out" you get a 5yd spread at 5yds of perfectly usable light showing plenty of ground texture and contrast.
- No top strap on the Manta
- Manta can be dimmed and it has an extra blue LED on the front and a second red LED.
- Gamma has a red LED on the battery case aiming rearwards.
So in summary:
Both perfectly excellent bivvy/camping/utility lights
Almost identical light output.
Both bright enough for running.
Mrs Stoner happily can run with either although seems to prefer the batteries on her forehead in the Manta over the Gamma with the batteries at the back. Lack of top strap doesnt seem to be a problem.
She does though have to tie another red LED aiming backwards to make up for the Manta not having the battery box LED. Only really applies on road stretches obviously.
I personally still prefer the Gamma.
