Thanks for the report GetUpnGo. I am glad to see more powerful LED lights appearing in the big stores so more folks are becoming aware of these.

I recently was using a similar flashlight, a Fenix L2D with about 180 lumens on my bars and a 4-7s light with about 120 lumens on my helmet. Those worked well until the turbo level on my Fenix stopped working. Then I decided to get a new light.

For my bars I bought a Dinotte XML-3 that is rated to a bit more than 1200 lumens. I found the lowest level, at about 400 to 450 lumens, to be all the is needed for road riding, although it is nice to have the other options, especially if riding in rough conditions or off-road at night.

For my secondary light -- an option if my XML-3 stops functioning -- is a Nitecore EC25. It has 5 levels of output: 860 lumens, 540, 285, 120, and 60 lumens. The Nitecore can be purchased for less than $50 and can run the 540 lumen setting for about 2 hours, and the 285 lumen setting for more than 4 hours off one battery. If you decide in the future you need more light, I recommend having a look at this light or similar flashlights. For the cost and run times, these types of flashlights make excellent bike lights. This is also a very small flashlight at about only 5 inches in length. The only drawback to these types of lights is the use of an 18650 battery which is usually not stocked by mass consumer stores, so you will need to buy a charger and several 18650 rechargeable batteries.

If you wish to stay with AA or AAA batteries, Nitecore also makes powerful, small AA light, the EA4. It takes 4 AA batteries and has excellent specifications. It is less than 5" long and about 2" wide. It can produce about 550 lumens for 2 hours and 300 lumens for more than 4 hours. Another excellent bicycle light. It can be bought for about $55.
