- Close-Range mode (wide, smooth, warm tint)
- User-replaceable LEDs (keep up with future technology)
- Comfortable enough to run without bounce
- Runs on one or two standard 18650 rechargeable lithium-ion cells.

The spot beam is what the Spikelight is famous for. We use a purpose-built crown glass asphere to produce a narrow beam like nothing else on the market. This is the beam that made people say “I want one!” so many times that we decided to start a business.
The flood beam is carefully designed to create a smooth wash of warm, comfortable light. It is designed to feel nice and make you happy. You can forget that you’re wearing a headlight because you don’t have an obvious spot of light in front of you. Instead, it’s just light everywhere you can see. We carefully choose emitters and lenses to be warm and friendly rather than stark like the cold fluorescent lights in a carpark or laundromat.
Check out the Performance page to understand our beams a bit better.
We designed a few user-interfaces to suit different preferences. The most popular is the competition style. This lets you choose how bright you want the flood, and only needs one button click to swap between spot and flood. So when you’re racing, you never need to cycle through all the modes you don’t want. If you also want flashing modes, SOS beacons, a battery indicator… etc, then these can all be added in to suit your preference. Or if you just want four simple modes which cycle through every time you click the button, then that’s ok too. Whatever you choose, it can always be reprogrammed later from a computer via USB cable. Have a look here for more detailed discussion about these user interfaces.
Below are some graphs that show how the Spikelight dims as it goes into power-saving mode. We haven’t shown the 5% and 1% power levels because they last far too long.
I find that I can use the 25% FLOOD power level for most of the night and just use the SPOT when I need it. This lets me get through a whole night without changing the battery.
Don’t worry about the exact beam distance in the FLOOD graph, only the relative distance is important. Note how the 25% level is much more efficient than the 100%. See the Performance Page to get a better idea of distances.
The V4 Spikelight was designed and built for 24-hour competitive navigation events. We like to run and jump as we bash our way through the bush, so the headlight needed to stay on our head and not bounce. This is why it has:
- Curved brackets to match the user’s head
- Extra wide elastic for comfort and stability
- Low weight
- Low-profile lighthead (reduces bounce)
- Adjustable angle and adjustable friction in the hinge
The Spikelight V4 really is a headlight that has been designed from the ground up by the guys who use it, not look at it. It doesn’t have pretty, streamlined curves, it has a goofy-looking design that is really comfortable and works in the field.
Small Quantity Benefits
We only make small batches of Spikelights at a time. This lets us keep up with advancing technology. So every time LED technology moves ahead, we are able to sell slightly brighter V4 Spikelights within a month.
We are also open to discussing your needs and building custom lights for you. Do you want a particular User Interface? Beam colour? White tint? Colour temperature? Battery option? Contact us and we can try to make it happen for you.
18650 cells are the sort of rechargeable lithium cells that laptops have been using for years. They represent excellent value in terms of energy-density, strength, and cost. The best part is that they are a standard cell, so you can buy them on eBay and in thousands of online shops. Check out this blog post for a more detailed discussion about these cells and their advantages.
Since we use two cells in parallel, you can replace them one at a time without ever turning the light off. The flexible cable even lets you leave the headlight on your head, and bring the battery case in front of your face while you change the cells. No more fumbling in the dark!
By using a standard cell, we are also able to buy new stock all the time. We never stockpile our cells so you always get fresh cells at the cutting-edge of 18650 technology.
Construction and Thermal Management
LEDs produce more light when they are kept cool, so our lightheads are machined out of solid aluminium for durability and thermal superiority. We mount our LEDs directly onto copper which gives us a huge thermal advantage over basically every other LED user in the market. We even use aluminium screws to improve thermal conductivity between components. The bottom line is that our lights start bright and stay bright where most headlights start to dim over time.
We’ve made some special efforts to keep our V4 Spikelights waterproof in the long-term. For example, The button which controls the modes does not penetrate the sealed body. So there is no dynamic seal to leak or fail. You get spare o-rings and a quality lubricant to ensure long-life. We also use standard o-ring sizes, so that you can always replace them for under $1.
Our V4 Spikelight bodies have been tested to a depth of 30m underwater – and survived. However, we can’t guarantee them for diving because this depends on the user maintaining the o-rings. Of course for anything less than diving, you’ll find that our headlights are very watertight.
