Not 1 But 2 White LED Torches to build

These LED torches produce a beautiful even spread of white light which is quite different from that of conventional torches using Krypton bulbs.

Design By John Clarke

These LED torches produce a beautiful even spread of white light which is quite different from that of conventional torches using Krypton bulbs.

Features

  • Super soft white light
  • Constant brightness over cell life
  • Indefinite lamp life
  • Extended cell life
  • Ideal for use with Nicad and NiMH cells
  • D cell version has brightness control

Conventional torches tend to produce a "hot spot" that can penetrate the darkness for some distance and they have a larger cone of much less intense illumination. Overall, they tend to have quite a narrow beam and you have to move the torch around a lot to adequately light up the area in front of you.

By contrast, these LED torches have a much wider diffuse beam, giving a very even spread of light without a central hot spot. For most of the time, this more diffuse beam is much easier on the eyes and the colour of objects is much more natural. In fact, it is like carrying a source of daylight around.

So these LED torches are ideal for bushwalking (at night!), even in very rough terrain, for illumination inside a tent or over a picnic table and as noted above, for emergency work on your car if, perish the thought, you break down at night.
