This video shows our first successful trial lighting an 11W 220 V CFL using a 1.5 V AAA battery and a CVS disposable camera flash circuit. In a future video I will show how we hacked the CVS camera circuit. I learned the idea from great folks using Fuji camera circuits; the CVS camera is similar to the Fuji but for patent reasons the battery has the opposite polarity (important to know – but the positive terminal to the long side of the holder!) and the contact points are much different (I hunted around for a while before finding the right place to connect the CFL, as shown in this video). Note that you have to bridge the left contact point and the bottom of the copper switch with a bit of solder (this will be shown in the next video); it isn’t just a matter of touching the two contact points. And be careful you don’t shock yourself — even with only a 1.5 V battery and no capacitor the circuit is live and hot! We demonstrated this lighting technique at a Catholic Youth Group symposium in Slovakia this weekend and all agreed these lights will be very valuable in areas that have no electricity or in disasters as ways of getting good lighting without using any dangerous fuels; great for developing countries (we are all working in Africa, for example, where we intend to teach others how to do this). We encourage everybody who can to send us their disposable cameras (take out your film yourself and send to a normal developer if you still use film) so we can make more of these for poor regions. Also note that now poor areas can use very small inexpensive solar panels to charge AA and AAA batteries which can be then used at night to run the lights.

NXP Semiconductors has developed an innovative, sustainable and highly efficient solar-powered street lighting solution, together with Philips Lighting. The groundbreaking Solar Gen2 solution, demonstrated by NXP at CES 2012, could have a major impact on energy consumption in urban areas at night. By charging street lamps during daylight hours, the new solar-powered solution from Philips Lighting and NXP can supplement the capacity of the conventional electricity grid, saving money and reducing CO2 emissions.

The key to the breakthrough lies in the combination of new High Brightness LEDs and unique patented optics from Philips Lighting, together with NXP’s MPT61x range of configurable ICs for Maximum Power Point Tracking (MPPT), which can deliver 98% power conversion efficiency in solar photovoltaic (PV) cells.

High powered indoor led lightihg. Very low consumption, high out put.

Testing out a Home Depot “Malibu” Pro-LED and a Lowe’s “Allen+Roth” LED path light in my side yard.
Normally, these fixtures would powered by a 12 volt transformer-timer like any other low voltage or “Malibu” landscape lights but I’m operating them with a solar-charged 12 volt gel battery through a Morningstar SunLight controller. They draw very little current (the Pro-LED fixture uses 1.3 watts and the Allen+Roth uses about 2 watts) but put out as much light as a 7 watt wedge base bulb. A lot brighter than the typical solar garden light which usually give out a very faint, blue glow.

I made this small 12 volt 4 LED (approx. 1w) solar emergency /general purpose light for the bedroom. I used a CD case as the housing for the light. It is powered by a 1.8w solar panel and a 7.5 amp hour battery. The solar charge controller has a timer function to control the LED and is programmable. I can make adjustments to the light output by adding more LEDs or a bigger solar panel if necessary. Google LED calculator for wiring and resistors needed.

These are 21watt, 11 watt LED light bulbs. There is also a 68 watt gigantic compact fluorescent bulb. With an ultra bright white roof and walls, you can illuminate grid free for a very low cost.
