Last updated 11-03-08

The Tesco Linesman Light is a fairly small, heavy-duty plastic flashlight that has a white 1 watt side-emitting LED in its business-end, and uses four AA cells to power that LED.

The body of the flashlight is a translucent red plastic with a rubber or rubber-like covering over most of it to aid in grip.


To use the Tesco Linesman Light, twist the bezel (head) clockwise to turn it on, and twist the bezel counterclockwise to turn it off.

Yes, it's as easy as that.

To change the batteries in the Tesco, unscrew & remove the bezel (head), throw it in the {vulgar term for feces}bowl, yank that silver handle on the front of the cistern down, and flush it away...O WAIT!!! YOU'LL NEED THAT!!! So just set it aside instead.

Remove the illuminator assembly (reflector with LED and contacts on its bottom) and set that aside too.

Tip the dead AA cells out of the barrel and dispose of or recycle them how you see fit.

Place two new AA cells in one chamber, both facing the same direction. Then fill the other chamber but install the cells the opposite way.

Place the illuminator assembly back into the top of the barrel; there is a plastic fin on one side of it that fits a slot inside the barrel; rotate the illuminator assembly until it "drops down" a bit.

Screw the bezel back on, and test your light. If it fails to come on, remove the batteries and reinstall them the other way.

Aren't you glad you didn't flush away that bezel now?

Unable to measure current consumption due to how the flashlight was constructed.

Because this is a "loaner", the punishments I normally bestow upon flashlights will not be inflicted upon this flashlight. I'm sure its owner would like it returned with no dings in the bezel or yukky old toliet water or desiccated rat pellets in the barrel.

So this portion of the web page will be ***SIGNIFICANTLY*** more bare than this section of the web page on a page about a flashlight that isn't a loaner or passaround.

The light produced by the Tesco is a pure white, with no yellow, blue, purple, or "rotten giraffe urine green" tint anywhere in it.
