Crazy powerful light

Excelente se ve a distancia lo único malo es que dura muy poco la batería aproximadamente dos veces a la semana lo tengo que estar cargando (usándolo diario 20mn) y que se carga mediante puerto micro USB y no tipo c, además la he probado en el lodo, lluvia bastante intensa y no se ha caído y la base parece bastante fuerte , se ve fácil a 3 cuadras de distancia

2 reasons why this is extremely bright. A is that it has a concentrated hotspot, ie very high lux (not talking about lumens). This is the value that you get on lux meters, the amount of light that you get at a certain spot some distance away. B is that it uses an orangey red emitter, easily 5-10 nm wavelength lower than other red LEDs. So your eye perceives it as brighter (brightest is at 555nm / green colour), more efficient use of power etc.I use 2 of these 350s as the hotspot is elliptical in shape and horizontally is 10 deg spread and vertically is 5 deg spread. So 2 of these gives me a 20 degrees horizontal coverage. I also use 2pcs of Magicshine Seemee 300 for even wider coverage esp with its additional Optic-trace LED firing sideways as i mount those horizontally on the back of my saddle (on a horizontal bar facing the rear).Need to fine tune a bit the vertical angle, the jagged teeth of the vertical angle adjustment is pretty "rough" and ends up either aiming the light too upwards or too downwards, esp for 1 of my light. I end up sticking some pcs of foam tape in between the clip on the light to serve as spacers so that the angle can be further fine tune. Very good light, you will be seen during day time. Use the STEADY mode for night time use, the intensity can be fine-tuned to a pretty low level. I think the run time for STEADY mode @ 350 lumens thereabouts (yes, full intensity) is 2hrs. This is one of the rare lights that you can run at max power in steady mode and still not overheat. AND also it can accept being plugged to a power bank and the light still stays lit, thereby prolonging the runtime a lot and limited by your powerbank only.

Very , very bright. I do alot of city communting, and keep a eye on my left mirror always, noticed right off, people give me more space. Only thing that needs improvement is change from micro usb to C. Came with 2 mounts, very secure on bicycle, quick release makes it easy to connect/disconnect. You get what you pay for, will defently get you noticed.

This is a good taillight - bright with many nighttime and daytime modes

Super bright, solidly built with multiple ways of attaching it to a bike. I am pleased with it so far.
