MoonHelix Max 250 Lumen Rear USB Bike Light

Not tested on long days of ride but its promising to be enjoyable!

Excellent bright light. Very very good. Its it worth more than the nebulae though? No, I run both, nebulae is just as bright.

The light fell off on my second mountain bike ride because the saddle mount does not lock in place. It just clicks in place so a slight knock and it will fall off. Otherwise an excellent light and the attachment for the seat post is much more secure. Hight on Bikes allowed a return and refund without quibble. So overall recommended unless you want a saddle mounted light on a mountain bike.

My only gripe with the product is that it uses this Garmin-style of mount which is SMALLER than the regular Garmin mount. So if you have a saddle mount intended for a Garmin Varia light - the Moon Helix rear light will be incompatible and you'll have to use the included mounting options.Fortunately, Moon include a lot of options. There is 1x saddle mount (use the also included zip ties to prevent this falling off - there are holes in the saddle mount specifically for zip ties), 1x seatpost mount, and 1x bag clip mount.The light is really bright, and there's enough options to satisfy but I just leave mine in the "Steady mode" where it's either really bright, or a bit dimmer at the press of a button.
