Energy & Light


Wuben C2 Flashlight

My (budget) Wuben C2 2000 Lumen Flashlight has a range up to 358 meters, using the proven technology of a Luminus SST40 led. It has a rechargeable 21700 battery (and is to-some-extend 18650 battery compatible) operational up to 300 hours and it can function as a power bank. It has the necessary IP68 waterproof rating and passed the 1.5 meter drop test. It weighs 185gz including the 21700 battery. That’s the techno-talk out of the way.

Usability: I like the amount of power-modes on this torch:

  • Turbo 2000-700 lumens, 1 min + 3 hours
  • High 1200-600 lumens, 3 min + 3.5 hours
  • Med 400 lumens, 5 hours
  • Low 130 lumens, 15 hours
  • Eco 5 lumens, 300 hours

These are included in the memory-function. It has two blink modes: Strobe and SOS. There also is a Electronic lockout, it shows the battery state and has a charge indicator. There is an option for a ‘breathing’ indicator when the light is off, enabling you to find the headlamp in the dark . All is operated easily with the one button.


Wuben H1 Headlight

My prime headlamp is the Wuben H1. It has outstanding waterproofing, it’s rechargeable, very robust/sturdy and has loads of power if needed. It has two light sources. A dimmable 1200/400/80/1 lumen main light reaching 125 meter and a 10 lumen (red/white) auxiliary light. IMHO, the main features are:

  • IP68 Waterproof.
  • USB Rechargeable 18650 2600mAh Li-ion battery.
  • 1200 Lumens.
  • It has a blue ‘breathing’ locating light, enabling you to find the headlamp in the dark.

This is an excellent headlight if a strong light is needed, in combination with being active. This headlamp has a good fit, keeping position very well.


Charging Kit

exposed gear

All my charging needs are solved by this small DIY charging station. A total of 7 Gopro batteries, 2 Nikon batteries, a Gopro remote, a Flashlight, a Headlight, my Powerbank and my iPhone are charged by using one power plug, needing one wall outlet.
All chargers are gathered on a 215mm x 130mm carbon fiber tray, with the powerbank underneath it. All usb wires are plugged into a two Quick Charge (QC) 220v to usb adapters (Quick Charge: managing power delivery by communicating with the power supply and negotiating a voltage.)

It’s all packed into one ultralight double compartment cube, with a mesh top to allow warmth to escape. It has one lead coming out, so when I charge (at, for instance, a lunchroom) the content of the board isn’t visible.

DIY Bee Wax Candle

Our all time favourite lightsource (and smell) must be the candle. I make mine by melting Wachsman Bee Wax pellets and a Candle Wick into an Elephant Box 50ml dressing pot. This wax is of a extremelty pure medical quality. The pot has a silicon lid, which can be closed when warm.
