DISCO DAVE'S TUNNEL GUIDE
Lighting
Headtorches
A Petzel double AA battery headtorch (cost around £20.00)and the Petzel 4.5 volt Battery headtorch (cost £25 oo) are probably the best available on the market (they do however require regular cleaning because of dust ). The 4.5 volt version omits a stronger beam and is a more robust than the double AA . The 4.5 volt batteries though can be hard to obtain and are bulky. This is contary to the double AA which is very compact. There are cheaper alternatives available but in comparison they are shoddy and unreliable.
Candles
Candles are usually donated. In desperation a box of 250 manufacturers reject candles can be purchased for around £30 00. For obvious reasons don't leave lit candles beneath shoring or near combustible material. Make sure the bottom of the candles firmly wedged in a bottle and on a level surface. Be frugal in their use. Creating something equivalent to a small church mass in your tunnel with a lot of candles is just wastefull as well as dangerous .
Electric lighting
It's hard work taking dead car batteries out from the end of a tunnel to be recharged. Bear this in mind when installing lighting. Long halogen lights will quickley eat up battery power. A lenghth of fairy lights however with the wire covered with insulating tape makes a pretty and comforting addition to a dark tunnel. Remember don't it take for granted that local people will recharge your batteries regardless of how many you use up. Use power wisely.
