Has anyone tried this light

https://www.4sevens.com/product_info...roducts_id=486

I ran across this by accident and do not recall any mention of it on the forum. It looks like a winner. Has anyone had experience with it?

For $75 including mount and running on generic AA's, I think it is worth a look if the mount is sturdy and it puts out a decent beam. The 6-hour run time would be more convenient for weekly commuter riders and for us occasional evening riders. And it puts out 20% lumens and has a 50% longer run time than the Fenix on high so it would be worth the extra dollars.

$62.50 - flashlight

+ $7.49 - twofishblock
https://www.4sevens.com/product_info...506b8fb97a548f

= $69.99 for the package versus $76.

Since these are two different sources now, would there be two shipping charges making the prices of the Fenix/fishblock equal to the Dosun M1?

I think this involves further scrutiny. Any volunteers?

I am light poor so I will have to wait for my Vega or PT SW3 or Fenix to fail before I purchase any more front lights.

I left out the bilevel beam pattern and cutoff shielding like a car headlight. Pretty impressive package for a 4-AA power source.

$76 dollars for only 120 lumens? That's expensive. You can do way better then that; even Cygolite has 10 watt headlights that would make that look dim for that kind of money or for another $15 you can really outshine with 16 watts from Cygolite.

There is a lot more to evaluating a light than lumens per dollar. You have to look at several factors.

Self-contained unit-no wires or external battery, circuitry to run bright until batteries are exhausted, has bi-level beam, cut-off shielding, and uses rechargeable AA's.

I would compare it to a Dinotte Pro Series at $129 with batteries and charger deleted. The Pro Series advantage has 200 lumens, which is 80 more, and the ability to purchase a larger battery carrier to increase run time. But it would have an external battery and wires, no bilevel beam or cut-off shielding, 2 hours less runtime at lesser lumens (50%=100 lumens versus 120 lumens for the Dosun assuming 4 AA's, and would cost $53 more.

This looks like a high quality, self-contained unit at a good price assuming it performs according to it's specs and you are purchasing it for road riding. The Dinotte's originally had 120 lumens and I have seen those in person and that is a good amount of light. You cannot tell a lot of difference between the Fenix on high at 107 lumens versus turbo's 180 lumens. So let's not get hung up on lumens, here. Let's look at the total package benefits and take it's lower price point into consideration.

What I would like to know is if anyone has tested it to see if it is up to the job?

Would anyone care to speculate whether the cut-off shielding gives more effective light and how much or is the only benefit that it shields the light from oncoming motorists and cyclists?
