Nicely put together rear emergency back up light
Weight: 31g Contact: www.raleigh.co.uk
Moon’s Gem 3.0 is intended as a get you home safely back up rear light or the sort of thing you might take along to the summer race meet. Light, discrete and boasting cutting edge design, but most importantly of all delivering as a reliable and very convenient extra light attached to luggage and clothing. However, impressive as the seven to eight lumens are, the tiny pronounced LEDS don’t have the same presence as a bigger light, which can prove crucial negotiating junctions in unlit areas.
Common to the Moon range it sports an attractive brushed aluminium body, a clever adjustable strap with sufficient give to entertain most diameters of seat post/stay, although satisfactory grip on oversized 6061 aluminium carrier rod proved challenging. However, the 3.0 differs from its siblings in so much as the bracket detaches, revealing a handy clothing clip compatible with most tabs, jersey pockets and messenger bags.
A transparent red reflector runs around the perimeter, revealing the Li-ion battery and intricate parts, although while adding some token safety it doesn’t appear to radiate light. Four tiny LEDs sit proud of the brushed alloy panel and titter enthusiastically at the command of a dinky switch. Pleasing to the eye, it’s a bit hit and miss even with dexterous digits and positively frustrating wearing full-finger gloves. That said there’s nothing remotely toy-town about the build quality and despite my initial doubts the design seems highly water resistant in everyday use (although I’ve been very diligent in ensuring the dust cap’s firmly in place following USB fuel ups).
Charge times have proved pretty accurate ranging from three hours fifty minutes and seven hours thirty in high and flashing modes respectively. Powering up, the little diodes are surprisingly bright (you certainly wouldn’t gaze straight into their glare) proving most useful in strobe and flash settings, although they had a tendency to become lost in the clutter of neon shop fascias and other light pollution on busy high streets. Friends suggest we registered on their radar from around two hundred metres on a dry, clear night and the 180degree projection is adequate as opposed to astounding.
Meets the design brief but best as a back-up light

Tell us how the product performed overall when used for its designed purpose
Moon's Gem 3.0 works very well as a chic, minimalist get-you home light or as a complement to existing lighting when attached to jackets, jerseys or luggage. The light is very bright but not particularly powerful and inclined to become lost in the excitement of the town centre. Similarly,other traffic drew very close along country lanes before acknowledging our presence. The Gem 3.0 will certainly get you home in emergency but wouldn't be my mainstay.
