but like holding a car headlight when you need to find your tent from a field away. LED's just can't do this.
Not entirely true.
A 5 watt batwing LED from lumileds with a lens to refine the beam into a spot will throw a beam over a huge distance.
cavers using a single 5 watt LED have found it too powerful as the scatterback hurts their eyes :shock:
they are also much more efficient, these and future generations of LEDs will replace incandecant bulbs in the next few years.
