For flashlights you don't use much, make sure they take AA cells, and then put lithium batteries in.The_Virginian wrote:for your kits/car/home LED flashlights are real winners...

Are their other charges that aren't attributed to generation, transmission and distribution?
If I add up the tax and other misc charges I'm getting over 15%.
Lithium has the best shelf life and cold temperature characteristics of all commonly available battery types.
I'm personally opposed to things that take coin batteries. The embedded energy in a coin battery is nearly as much as that in an AA cell! Plus, AA cells are more versatile and ubiquitous: as I pointed out, you can choose to use high capacity, earth friendly rechargeables, long shelf-life lithium, or you can be a part of the problem and use cheap alkalines. (In an emergency, you can get alkalines almost anywhere, unlike "coin" batteries.)The_Virginian wrote:Of course a keychain LED w/ a lithuim coin batt. would solve most of your emergency lighting needs...

Compact fluorescents are a good alternative for more 'homely' rooms.
LEDs lights are very expensive, but good for task lighting because they are very tightly focussed, so virtually none of the emitted light is wasted. However, they are of comparable efficiency to conventional incandescent bulbs, so are not a suitable replacement for 'area' lighting.
M400 CobraHead-Styled LED Streetlight Will Have You Seeing Stars.
TORRANCE, CA — February 6, 2004 — Doing its bit to aid the worldwide Dark Skies initiative, LEDtronics introduces direct incandescent replacement M400 CobraHead-Styled LED Streetlights. These new streetlights eliminate the unwanted glare, light trespass, energy waste and sky glow that accompany traditional incandescent streetlamps. An estimated 30% of outdoor light generated in the U.S. goes into space, flooding the skies and creating electric haze that reduces stargazing. LED Streetlights shine light in the direction where it is needed – at ground level – reducing the amount of light that is lost to the sky and improving overall nighttime viewing. The LED Streetlights meet IES street lighting standards. (Test results may be downloaded from the LEDtronics website: www.ledtronics.com)
The LED cluster lamp contains 400 Warm Incandescent-White (3200K) LEDs arranged in a light optimizing design. Architects, urban planners and lighting professionals will find that the 3200K White LEDs emit a pleasing warm incandescent-white light and have a diode life of over 100,000 hours that makes them excellent replacements for standard incandescent lighting along minor roads, pedestrian walkways, in parking lots and for maintenance-intensive and ornamental lighting applications. This LED Streetlight lamp with its 19-Watt power draw and high-intensity light output make it ideal for use with alternative energy systems like solar and wind power. Using LED lamps with renewable energy sources helps to reduce the reliance on fossil fuels.
When purchased independently of the housing, the lamp is available in both Type 1 and Type 2 styles. Type 1 lamps have to be hardwired into the cobra head fixtures. The Type 2 lamps feature male 39mm mogul bases that screw into the socket of the fixture. The LED Streetlamp may be purchased as a retrofit lamp for existing installations’ old style cobra head fixtures or as an integrated part of a complete assembly that includes the housing and lens. LEDtronics offers a die-cast aluminum MSCL M400 Luminaire CobraHead-Styled fixture with an electrocoat gray finish, universal two-bolt slipfit joint, adjustable mogul E39 standard base socket (house side), and a flat glass lens. Standard voltage for the LED Streetlight is 120VAC; other voltages available are 12V, 24V, 28V and 240V. Optional LED colors are red, green, orange, yellow, cool white and blue.
Light Emitting Diode (LED) technology with its inherent energy efficiency makes an excellent accompaniment to photovoltaic-based energy systems. Solid-state design renders LEDs impervious to electrical and mechanical shock, vibration, frequent switching and environmental extremes. With an average life span of 100,000-plus hours (11 years), LEDs operate reliably year after year and are virtually maintenance free.
