[Closed] Tesco torch help

Oh dear.....here we go.

I bought the C cell powered one. Realised that the beam was too focussed, so stuck a ball-end dremmel tool into the perspex lens block and rounded out the small convex lens part at the end of the hole. Result: wider beam focus.

I also played around with manufacturing an orange peel reflector using a foil cake case. This created a wonderfully smooth light pool, but on the trail this tended to light the bushes on either side of the trail and not much in the middle.

awesome thanks i'll try the latter before the dremel job

Take the lense out, wrap the foil tightly round the perspex block and carefully cut a hole where the LED will poke through.

The problem with the foil cake case is that:
1) there's no glass, so the LED is open to the elements
2) it's metal and might short across the LED if you're not careful (maybe a bit of tape to insulate it?)
3) it's fragile because of point 1

The light created looks great in the garage (and is an improvement IMO on the basic use of it as a torch) but on the trail when bombing along you feel as though the light pool is black in the centre as there's no penetration to the beam at all.

The mod to the lens works well, don't be afraid to be rough with the 'machining' as the majority of the beam focus is done using the outer egde of the lens.

I was in Tesco's last night and the AA 3w was seven pound something.

still looking for a direct link to a new optic, or even if someone could say what LED is fitted in the tesco torch so i can go on led suppy and find the relevent optics.

Direct link would be better though 😉

Go to candle power forum and search on "sputter", basically a few layers of hairspray in a fine mist to create an orange peel esq reflector.

I've collected a few useful links for the Tesco Torch mods here:

Admittedly they are tailored to my interest in replacing the optics of the C cell, and maybe running a different driver and battery pack. Hope they help.
