![]() "Day Fl" strobe on mine is listed at 180 Lumen (20, 50 and 100 are other flashing options, maybe newer version?). ![]() This reduces risk of being hit from side at intersections and impinges on driver peripheral awareness as they are passing ( when they would normally have forgotten your existence)īuild quality, mounting options, USB connector and cover are all excellent. The big plus for me is the lights are bright through 270 degrees. PIcked up a front/ rear set from Merlin Cycles (at NZ$95, by far the best price I found) Very powerful but generally usable rear light with sensible run to charge ratios That said, while I've been grateful of the 100 lumens in very specific contexts, I'd suggest it's generally more than most of us would need. The Nebula gives scope for pretty much every condition, has ample presence and good run-times. Even on my low-slung Bob Yak homage, the average driver seemed to take notice at 225m, and better drivers calculated the additional length when overtaking. Beyond, I've been inclined to click over to 50% flash. Used with other more powerful lighting when towing a tagalong/trailer, strobe has seemed up to the job for the suburbs/outskirts of town without being too brash in stop/go traffic. The general consensus suggests I came on most people's radars at 180m, maybe a little further on crystal clear nights and dipping slightly in town. The 10-lumen flashing mode wouldn't be my first option for long stretches of unlit road, but run-time is excellent, 20:33 – within 7 of that cited.Īs my sole source of rear lighting, say on an all-nighter, I'd go for the 20-lumen strobe. I've managed 7:21, which is close enough, allowing for the fact that I'd changed modes a couple of times during that phase. Low is reckoned to return 7:30 from a full charge. Even allowing for other light pollution, a couple of riders drawing beside me at the lights reckoned they could pick me out from 150m. When it comes to social riding, the low steady or 10-lumen flashing options are arguably best. > Buyer's Guide: 14 of the best rear lights I can appreciate its value in brief sections of thick fog, but beware it'll also drain the battery in just over an hour. That said, some riders commented they wouldn't want to be following it at close quarters on a group ride.ĭaylight aside, I've not felt the need for such a high setting. Depending on lighting conditions, I'm told it's obvious at 200 metres, dipping to 100 or so from the side, at T junctions or roundabouts.Ĭrucially, it's assertive rather than aggressive, so approaching traffic doesn't get an eyeful. Starting at the top, the 100-lumen settings are unmistakably bright, though not uncomfortably so during the day. ![]() The lens uses collimators to project a very precise and pure 270-degree arc of light, which tends to reinforce your presence and encourage a wide berth from overtaking traffic.Īside from the obvious seatpost mount, I've tended to opt for the clothing clip, which is super-tenacious whether tethered to a jersey pocket or dedicated tabs on jackets/luggage. A memory function ensures you can default to a favourite setting. Flashing follows a similar narrative: 10 lumens, 50 lumens and 100 lumens, plus strobe, which is a town-sensible 20 lumens. The battery life indicator is pretty intelligent, giving plenty of opportunity for clicking down to conserve power.Ĭonstant modes are: low (15 lumen), standard (30 lumen), high (45 lumen) and overdrive (the full 100 lumens). These feed from a 3.7-volt 800mAh lithium polymer cell, which mains charges in a very competitive (and office-friendly) two and a half hours. Using Chip on Board (COB) technology, Moon has loaded the Nebula with 50 diodes and eight (four steady, four flashing) modes to choose from. Mount size:Rubber band mount (fits φ 12.0-32.The Moon Nebula's 100-lumen highest mode (steady and flashing) is arguably overkill save for really foggy conditions, but thankfully the size, diode distribution and wealth of alternative settings on offer keep things practical in pretty much every riding context.Battery: Lithium Polymer rechargeable battery.Attaches to the existing CatEye bracket by using the optional Spacer X.Battery Auto Save (The mode automatically changes to flashing when the battery power gets low.).USB rechargeable (Micro USB cable included).Lithium-ion polymer rechargeable battery.Mounts securely to seatpost or seatstay with the rubber band (Ø12-32mm).The USB rechargeable Rapid X has the low battery “Auto Save” function automatically changes the light pattern from the current mode to flashing, providing an additional hour of riding safety. ![]() Provides a bright, powerful glow with incredible side visibility.
