At road.cc every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Good scores are more common than bad, because fortunately good products are more common than bad.

The Moon MkII Rechargeable COB Front Light is small and very bright. The unusual shape provides good all-round visibility, but can make it a bit awkward to find a suitable place to mount it.

It's a light more for being seen by, rather than seeing with, and would seem to be aimed squarely at urban commuters, with simple rubber O rings allowing easy fitting and removal, and a USB port for easy charging. It performs well in this role, with good visibility from all sides and eight different modes, four of them flashing.

On the 'strobe' setting the light blinks very quickly, giving out a claimed 30 lumens for 11 hours. I can see this setting coming in useful for riders who like to ride with a safety light in the daytime, but I didn't use it on my commutes, preferring instead to use the brighter, conventional flashing modes – the brightest giving off 130 lumens for up to 2.5 hours.

The unit has hooks on the sides for the supplied O rings. One of the hooks is a bit narrower than the other and helpfully retains the ring when the light is removed from the bike.

A soft rubber bracket covers the USB port and provides a flexible surface for fixing to the bike. This bracket isn't permanently fixed to the light and can fall off when the light is detached; losing it would be a pain but not the end of the world, as spares are available.

The rubber bracket also seals the charging port from water/road grime ingress, which is the only potential weakness, but when it's strapped to the bike it's held in place securely.

Fitting the light to the handlebar proved a bit troublesome – the long, thin shape makes it hard to find a wide enough space between the stem and your bar tape. When fitted horizontally in this area, the good side visibility leads to occasional dazzling when you're bending over the handlebar.

It's not a light you can easily fit to a helmet, and I eventually attached it vertically to the head tube, where it proved very successful.

The only potential problem I found is that the battery warning light isn't very obvious, so it's easy to miss that you're running out of juice. And when the battery does run down, the MkII doesn't automatically change to a lower setting, or get dimmer like lights of old, but switches off suddenly. Not a problem if you keep it topped up, of course.

Verdict

Very bright and compact, it performs well if you can get over the mounting issues, and be sure to keep it charged

Nicely put together, although the rubber bracket can come loose when it's off the bike.

Rate the product for performance:
 
6/10

Easy to use, the light does its job well. The sudden loss of light when the battery charge is low is a potential problem.
