That was done hoping to get to build higher power lights if I got the chance and the right LEDs became available. Fast forward a few years... Combine the freshest Cree XPL-HI with building out the driver to four channels and revised firmware, and the Oculus 3000 is now the wildest self contained bike light or flashlight you could imaging biking or going on duty with. The lower outputs of L2 - 4 are the same as L3- 5 on the 1800, but with ~15% longer burn times for each brightness. L1 is double the output of L1 on the 1800, ~140lm, but with ~25 hours burn time. |

Don't you know that really high intensity bicycle lights not only keep you safe but also give you that all over warm and comfy feeling? I'd reckon that if one had a really, really, bright, flashing, front and rear light AND a helmet why, he/she/it would be nearly immortal. (notice how politically correct I am. I used to say "he" or "Her" but as I read in the news that a number of the Stated now have three sexes, male, female and "X" I have had to change my ways) |

I guess there's no downside other than slightly higher component costs, but are 3000 lumens needed very often? What's the run-time on the highest setting? I can see an occasional need for the higher output, at high speed in unlit areas, but in my experience 1500 lumens has been just about right for commuting, even on unlit multi-use paths.

Oculus ($150), CatEye Volt 1600 ($176), and Lezyne Deca Drive 1500xx ($90). I prefer lights without a separate battery pack, even though the run-time is shorter, and with the Oculus you can carry an extra battery., --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |

Interestingly the CREE specifications http://www.cree.com/led-components/products/xlamp-leds-discrete/xlamp-xp-l-high-intensity mention "Max Light Output (lm) 1095 lm" Accordingly I conclude there are at least 3 LEDs in your flashlight. -- JS |

The high power lights have had to move to multiple LEDs, both for the greater illumination and for thermal management. Most have a temperature sensor as well, which reduces the current through the LED if the temperature is too high. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus |
