Consider the Serfas 1500 or 1600 https://www.serfas.com/shop/products...0-e-lume-1600/

ok, just received my Taz 1200 - disappointed in the mount. i thought it was everyone else, i assumed for sure that i woulnd't have teh problem and even wrapped with the provided rubber grips (not just the silicone strap) and the light still slipped a bit and i adjusted at least 3 times on a very short 1.5 mile ride around the neighborhood to see what it was like.

oh well, what a disappointment, the beam patter was fantastic and the color of teh LED's was great too but i can't justify having to slow down to adjust the light every few minutes during a ride. what a shame.

also, the light would shut reduce to low power after a few minutes - it was hot but it was also 30 degrees outside.

i'm conflicted. this should have been a great light, but it just didn't fit the bill for me. i took a bunch of pictures, if anyone is interested, let me know.

The slipping might not be a deal killer if you can make a shim and if it prevents slipping.

But the reduction to low power after a few minutes is a deal killer.

That's a common problem with any heavy, off-balance device that uses a simple rubber band strap. Even my lighter weight L&M Urban 500 can shift on my chrome and plain aluminum bars. Cinching it tighter isn't a practical option for me -- arthritis in my hands and fingers makes that difficult.

No shifting on my Univega's steel flat bar that's painted black enamel. So I figured the chrome and plain aluminum bars just needed some tooth for rubber band and clamps to grab.

On my road bike's plain aluminum bar, I wrap the L&M rubber band strap partway around the handlebar tape. That works. For a chrome or plain aluminum bar without bar tape I'd add a wrap of tape (blue masking tape works) or a thin rubber shim. Many bicycle doodads include rubber shims to compensate for different diameter bars, stems, head tubes, etc.

My Ion Speed Pro video camera includes a very secure screw-on clamp but it can still shift on chrome and plain aluminum bars and stems so I use the rubber shims.

The Serfas E-Lume lights use the excellent Serfas universal bracket. The bracket is mostly rigid plastic with a low-stretch rubber strap and camming lock lever. The rubber strap must not be overstretched -- it can break after repeated excessive stretching. (Serfas replaced my clamp at no charge when it broke after two years -- probably my fault for not pre-adjusting the strap appropriately when I moved the mount between my hybrid's head tube and errand bike's suspension fork.). But the strap features multiple steel pins that fit into niches in the clamp body. Make the rough adjustments for diameter using the pins. Then cam the lever locked to snug it up. It will hold securely on any tube, any finish.

Once the bracket is attached to the bar, stem, head tube, fork, etc., it can be left in place and the light removed from the mount. If you have more than one bike, get a universal bracket for each and move the light between 'em.

I'm considering one of the higher power Serfas E-Lumes so I can run it on medium or low. It'll run 4-6 hours and still have plenty of light. After just barely making it home from long night rides with the otherwise excellent L&M Urban 500 on medium, I realized the maximum output on lights under 500 lumens should be considered only for relatively short rides, commutes, etc., but not for those of us who enjoy long rides on summer nights after the temperature cools down a bit. A more powerful light that can be run on medium or low will last much longer per charge.

pretty much anything with over 1000 lumen will need airflow to keep it at max. Gemini is known for having "underdimensioned" cooling fins.

Also all self contained and heavy lights will move around a lot I have noticed, all mounts simply suck. those engineers have some unrealistic expectations of how good a big o-ring really is. its not very good at all.

you can always make some more permanent install with hose clamps. 1 around the light and one around the bar at 90 degrees out from each other. or maybe modify the clamping thing of your light with a hose clamp somehow.

if it used a black rubber o-ring as a fastener, your local hardware store has a drawer w various sizes, maybe you can use a smaller one. pics? yes, of course!

btw, for accessories, sometimes their supplied inserts & shims are not enough. I recently used a cpl inches from an old bar grip. sliced it, rolled it off, then slid it on the accessory mount

It may be because of the high speed of car driving. The bike light manufacturer should develop one. It would be very useful for a long-distance commuting. Maybe they already did. I'll have a search.

Hope they can invent an integrated one and lower the cost.
