The Diablo Mk4, the new update to the Exposure Diablo Mk3, gives new meaning to the concept of “head light.” This helmet mounted light, which was just announced, casts up to 1,100 lumens anywhere you turn your head.
It comes with a USB charger so it can juiced up from an AC outlet or from a computer port. It looks to feature the same weatherproof construction of the previous model and can easily mount to most helmets. On full blast this one will offer about an hour’s run-time, which could be great for commuters. On a lower settting it can obviously go the distance. But for those who want to cast a lot of light for a long time, such as a 24-hour race or something, there is even an optional 3-cell external battery that can offer up to eight hours of run time.
We’ve seen a new trend this year with bicycle hub-attachments that power lights and more. Earlier this month we noted the 
The new Thunderbolt silicon USB rechargeable bike light is set to arrive later this summer from Serfas, and will be available in seven stylish colors. The water resistant headlight (above) promises to provide 90 lumens of light from a strip of 15 micro LEDs, with a run time ranging from 1.5 hours on high beam to 6.5 on low, along with 3.5 hours on blink and a full 9 hours on low blink. 
We first profiled the 
Knog have been going strong for several years making silicon bicycle lights, and the company has unveiled its new set of USB rechargeable lights, under its Blinder brand. There will be new models – the 1 and 4 – that will be encased in metal and silicon, meaning these will be both watertight and bright as the lights will feature either a single LED or four LEDs respectively. And because these are factory-sealed they will be totally waterproof and even submersible – not that we can figure out why anyone would put them underwater.
Motion tracking devices have made some major strides in the last couple of years, and now InvenSense, a provider of motion tracking technology, announced this week the availability of its MotionFit System Developers Kit (SDK). This promises to help accelerate design and commercialization of wearable sensor devices for the growing fitness and remote health monitoring markets.
Heat is often the side effect of powered device. Engines give off heat, even light bulbs give off heat – most of the time this is a side effect that results in what is wasted energy. On the other hand heat from fire is another form of lost energy because besides providing warmth the heat does little else.
Feel the burn, that’s one way to know you’re doing it right. But Nike has another idea – the company has introduced the FuelBand, a wristband device that is designed to measure daily movements of the wearer, tracking steps taken and calories burned. But the device also features the NikeFuel, a fitness metric that utilizes the rate of oxygen consumption and motion.
With winter now actually here the temperatures outside are dropping and that means it can be hard to keep warm. But the Columbia Circuit Breaker jacket could help wearer’s get hot under the collar or just about anywhere else. This jacket uses the same Omni Heat thermal reflective technology that we reported on last week with 
Riding a bike at night has numerous hazards, namely that fact that drivers can’t see them. But now a start up from Utah father and son team Rick and Brandon Smith might add some light to the night. LED by Lite essentially consists of four strips of silicone-encased LED bulbs, where two mount to the front fork and two to the rear. Following the tradition of car lights it is meant for white in the front and red in the back, but unlike car lights these can be seen from 360 degrees.
