Fenix single AA for helmet light?

I read some about hiking lights people have been picking up so I got one at target, ~$20. I currently just have a dinotte 200L up front and it was great but just this cheapy 80 lumen (3xAA) spot light was a huge addition, I wouldn't want to ride without the dinotte on the bar though. I actually use it on low most of the time and it gives enough light for my early AM commute.
My problem is heat and weight. It doesn't create alot of heat but it blocks my helmet vents and the 3xAA in back make it really heavy. Plus it is zip tied on so I can't just un velcro it when I don't want it.

There seems to be alot of love for the L2D Premium but has anyone used the L1T V2.0 or similar for a helmet supplementary light? It is 90 lumens on high so it is better then my current light and it should not only be lighter but it won't block my vents. Is the L2D premium even noticable centered on top of the helmet weight wise? If so it may not be worth experimenting with a smaller light. I'll be on my bike for a little over 90 minutes on my morning commute and the current 3xAA is causing some soreness.

I am using a Rexlight 2.0, 1 X AA Cree XR-E, for my helmet light. It gives about 2 hours of runtime on a battery in either high or strobe. I use a Cyclops BikeBlock to attach to the helmet.

The Rexlight is very similar to a Fenix L1D. I use Sanyo Eneloop rechargeable batteries and on long rides, I just take an extra and change partway through the ride.

I also tried a Jetbeam C-LE (runtime too short), Fenix P1D-CE (runtime too short, does not work well on rechargeables) and a PlanetBike Blinky (too dim).

I like the concept and will keep using it during the winter. As a hint, I used a wedge of a synthetic wine cork under the BikeBlock to adjust the height.

I use a Fenix L1D mounted with a Zefal Doodad Plus for a helmet light. The Fenix is very bright and it's weight is hardly noticeable.

Go to your local Michaels Craft Store w/ a 40% off coupon from the paper, & get the 3/4" x 12 ft. velcro wrap for $8.99 before discount. This way you can take the light on & off. Just cut to fit.

As for the other light on the helmet, I can't answer that ?.

Good luck,
Chris

After a few weeks with the helmet light, I can say for sure that a strobing flashlight on a helmet is the best "attention getter" I have used. Better than a blinkie on the bike because it is higher, so cars can see it and because it turns with your head, so if you look at a car on a side street, they get the benefit of a 100 lumen strobe. Don't leave home without it.

If you don't mind not having flashing & a useless "low" mode, this is a nice single AA light

It's less of a spot than a Fenix, but IMO, just as bright.

I've tried the 2xAA Fenix light on my helmet with a Fishblock and after a few minutes, can't tell it's there. Good call.

I've only used my L2D a few times so far, but my neck was a bit sore afterwards. I think it's more due to moving my head to aim and re-aim the light, then holding it steady at an odd angle, instead of the extra weight. I'm assuming I'll be OK after a few rides.

My helmet, a $50.00 Bell Furio, is 330 grams. The L2D two AA light is 113 grams with batteries. One AA battery is 28 grams, and the smaller flashlight is only 10 grams or so lighter. So the weight difference (28+10 grams) isn't a big percentage of the helmet + light.
