    Lighthead-only options shootout

    Since I have a bunch of nice 18650's already, I'm shopping around for lightheads that I can use with a battery case such as: https://www.gearbest.com/diy-parts-a...pp_148900.html

    I'm not quote sure which lighthead to get for either helmet or bar. I've been researching and my options look like this, from high to low end (adding links for any other readers who might not know where these are found)

    Gloworm- https://www.action-led-lights.com/co...gloworm-lights
    Mtiger- Products List
    BT40s- https://www.amazon.com/Revtronic-BT4...0-Lumens-Light (don't know much about this light but it seems to be popular around here as a handlebar light)
    Kaidoman- http://kaidomain.com/bike-lights-and...es/Bike-Lights (KD2 and BL2 seem most popular)

    I'm especially confused by the ~8x different in price between Gloworm and the Kaidoman lights, seeing as how they share the same LEDs.

    So, what would you choose for bar and helmet? Thanks for any advice!

    Like my modded 2000lm Bt40s for the bars. No experience with the listed helmet lights. (using an ituo xp2)

    A little information on how your going to use your lights would be helpful (mtn. bike/road bike/commute/ride around the neighborhood?).

    Problem is that most of the decent lights are not going to perform well using that case. Gloworm, Mtiger from the list you have, that case will have issues running the lights at high output.

    What kinds of issues? Isnít it more about the cells than the case? If the gloworm X2 normally ships with a 4-cell pack and I assemble my own 4-cell case with high quality cells, I think I should be fine right?

    there is a lot more to it than that. If you compared the wiring in the branded lights and such, all larger guage wire. Not all the low current circuitry in the battery pack.

    Basically what will happen is good loss of run time and lights wont maintain their highest outputs near well because of all the resistance from the case.

    The case is designed to be cheap, like most Chinese lights. The 2 work well together. But branded high power stuff and those cases function, but very noticeable loss of performance

    Quality, features, accessories! With the KD lights you get a lighthead that has considerably less output than claimed, is assembled with the least expensive components, is poorly engineered for thermal transfer so will be heat sensitive + a simple band mount, but it is very cheap. All Gloworms use only high quality components and most likely produce more than the claimed lumens, Have excellent engineered lighthead aaand mounting systems (QR bar and helmet mount included in lighthead kit), have sophisticated UI mode programs (3 step mtn. program + 2 step hi/low commuter program) and programmable presets, a wireless remote on all but the Alpha model, and a warranty.

    Because of the battery setup you plan on using the Alpha is probably the best Gloworm option for you even though is doesn't have the wireless remote. Can be run effectively helmet or bar (with accessory W/W optic) and only requires about 60% of the current draw of an X2. A little less power but almost the same throw + makes a good combo (neutral white version) with the Revtronic BT40s.

    Another low current draw option is the C&B Seen 1900 3up. A little more powerful than the Alpha for less money but less refined/complete package. Here's a link to a thread on the 3up.

    Alpha on a budget. 1200 lumens for entry level price and you can swap optics
