Bests & Worsts Reviews from Amazon

Only had this bicycle lamp for tens days now, but have tested it out as extensively as weather has permitted and am quite pleased. Ordered this Nitefighter because it was the first multi-lens model to come with Cree's Neutral White XP-G2. Earth tones along the trail don't get bleached out, so natural elements such as branches, dry leaves, mud and rock are more recognizable, and obstacles more avoidable. Can't overstate this quality; have always found the Cool White tint of my previously owned bike lights rather disorienting, kinda mimicked intense moon or star light. Hours of pedaling through what appeared to be dreamscape would make me want to close my eyes and drift off to slumberland... not such a good thing to happen when riding a bike. Neutral White, OTOH, being closer to natural afternoon or morning light, keeps me feeling more alert and involved with my surroundings. It's a much happier experience over all. As it is still winter here, my night rides so far have not exceeded much more than about an hour and a half, the BT40S powered anywhere from Low to Turbo. From a full charge on the included battery, the indicator has only dropped from green to blue near my return home, meaning there is still up to 75% remaining. This is better performance than I've had from any other setup, so no complaints here. Was pleasantly unsurprised by the shape and scope of the NiteFighter BT40S' beam pattern. Despite its relatively wide angle, the throw from this thing's four (count 'em, four) emitters is pretty darsh darn good. Maybe doesn't reach quite as far as would a longer, reflector based spot light, but has much smoother and even distribution. There's no ringing or wasted spill; light fades gradually from the center without distict boarders. Haven't unscrewed the front bezel yet to swap in the extra-wide angle diffusing lens that's included in the package (because the default lens has been fine for all my needs so far) but expect that option would benefit more from an auxiliary little spot lamp you could mount on your helmet. NiteFighter has actually come up with a NW single emitter specifically lamp designed to complement the BT40S, might be a worthwhile addition for anyone who actually installs the diffuser and/or rides real technical track. Doesn't look like the manufacturer cut any corners here, and the results speak for themselves. BT40S is extremely easy to operate, even with heavy gloves on. Brightness is adjustable through four levels in either direction without having to cycle through Off, with the aid of a large soft-touch dual control button. One criticism: Low mode, at 30% power, still seems kinda high to me. Seeing as there are four levels, think maybe it could have started off at 20% or 25%, with more discernible differences between each press of the button. But that's just me, am sure others will appreciate the subtlety. Couple of bonus features not declared in the Amazon overview: Charge indicator LEDs remains unlit when the lamp is not in use, so the battery pack can remain connected without draining any power. And the two-whole-Amp charger gently flashes red near end of its cycle before going green once the cells have reached 8.4V - 8.5V. Like that there is a soft connection from the cell pack to the charger cable and a firmer, waterproof connection to the lamp head. Very well though out and implemented design.
