A common issue with solar-powered lights is that they often output a very weedy light beam. What I like about the PowerBee Solar Ray 36 is that the light output is equivalent to a 30 Watt mains-powered light bulb! Which is much higher than most other solar lighting. The Solar Ray 36 has, you guessed it, 36 high-brightness white LEDs, all powered from 3x AAA 750mAh rechargeable batteries. (more…)

Eterna LEDs Quanta 9W Light Bulb
I recently reported on Eternaleds Hydrolux light bulbs, well, they’ve been innovating again and they’re now selling their LED floodlight bulbs that have an 80% energy saving compared to their incandescent counter-parts. The Eternaleds 9W LED Floodlight and Eternaleds 18W LED Floodlight are a drop-in replacement for any screw-type standard E27 medium base socket, replacing conventional 50W and 100W incandescent bulbs respectively.

The Eternaleds HydraLux-4 is a fresh innovation in the area of lighting, since it’s a 4W LED bulb that produces the equivalent light of a 25W incandescent A-Shape bulb. The bulb is designed to last 35x longer than conventional incandescent bulbs (so 35,000 hours), saving approximately $157.00 over lifetime in bulb and electricity costs. (more…)

The Dynamo Pedometer with Flashlight is a number of little gadgets rolled into one. It features a pedometer which will count the number of steps as you walk or go jogging. You can also determine how far you’ve travelled and how many calories you’ve burnt off too. Great for when you’re out hiking or camping! The pedometer is charged up by using the hand crank on the side. Therefore you’ll never run out of power to run it. (more…)

With the push towards LED lighting (as filament lamps are due to be banned in 2012 in most countries), there is incredible research going on into lighting that offers the equivalent light output and light colour, but at the fraction of the energy consumption. The Zetalux LED light uses only 7 Watts of power, but is comparable to a 50-60 Watt Light bulb! The light is high efficiency and does not consist of any harmful raw materials. (more…)

Due to the fairly low light output of LEDs, it’s easy to see that LEDs offer great potential for micro-illumination, i.e. enough lighting for a very small area. LEDs offer very directional lighting, and this dictates what they can be used for without using special diffusers. However, Jason Bruges found a novel use for a wind powered LED light and has used them to light up a tower in Southbank (London, UK). (more…)

Lighting a large area with conventional lamps can be very costly to run in energy costs, in addition to installing the infrastructure and maintenance costs. However, with some careful planning, the use of green gadgets, such as solar powered LED bricks can be an attractive and practical technique for lighting pavements and other paved areas. (more…)

Sheds are usually awkward things, as they’re often dark, damp and a fair distance from the house (if you’re lucky enough to have a large garden). So if you want a light for your shed, getting electricity from the house is a lot of hassle and expensive. Using a solar-powered shed light means that you don’t need to worry about that. The solar power charges a NiMH battery in 8 hours, and gives you up to 3 hours of bright light in the shed. A great eco friendly gadget, that’s useful too. (more…)
