5.0 out of 5 stars Optical Terrorism, 9 Aug. 2012
This review is from: Moon XP500, 500 Lumen Front Light (Sports)
I wish I'd bought mine at the price currently offered by Amazon. Actually, I wish I'd bought both of mine at that price.

Anyway, on to the useful stuff.

It's not as large and heavy as you'd think - it looks like one of those bar-mounted lights you'd find in Halfords which might get you noticed in traffic, but it's so much more than that. I'd be tempted to say it could be used for offroading, but I have a road bike with 23mm slick tyres so have never taken it offroad!

Weighing in at 144g, it won't weigh you down much and the solid tool-free clamp only takes up about 20mm of bar space. It fits oversized (31.8mm) roadie bars as well as the slimmer MTB ones. The self-contained light unit clips in easily to the mount and stays fixed in place as long as you need it.

On full power it sends 500 lumens of light down the road for about 100 minutes. About 30 mins before the end of its discharge cycle (at the currently selected output level) the solid blue status light surrounding the power switch starts flashing red to warn you of impending darkness. Reducing the output level from 500 lumens down to 380, 240, 120 and 380 (flashing) extends runtime more than you would expect given the numbers, as it appears that the full-bore 500 lumen mode is the least efficient.

According to the specifications, the run times are:

500 lumens 1h40m
380 lumens 2h20m
240 lumens 4h
120 lumens 8h
380 lumens (flash) 4h30m

I have found that 120 lumens is quite satisfactory for unlit roads at moderate pace. The higher-power modes are even better - in the 380 lumens flash mode I have seen reflections from street signs more than 100 metres away. In daylight.

You also get a helmet mount (not compatible with the Scott Fuga, in case you happen to have one), and a mains charger which uses a USB cable, so you can also plug it into your PC to recharge.

One thing to be aware of - despite being an LED it still dissipates a good amount of heat at the higher power levels. The metal heatsink part at the front can get uncomfortably hot if you leave the light running while you are stopped.

Very highly recommended.
