UV torch
Wednesday, 25 November 2020  | 

Purchased this UV torch with focusing ability for our work in fine art conservation. Very pleased with the quality of the product and service from Torch Direct. The ability to focus the intensity of the beam is particularly useful, allowing it to be used effectively in ambient light conditions. Highly recommended as a portable tool for examining works of art and other painted surfaces encountered the heritage field (wall paintings/historic buildings etc...)

Great value UV torch, but not for Smartwater.
Thursday, 1 October 2020  | 

This torch attracted my attention 'cos it can use a 3.7v lithium 18650 cell, which gives it a much longer run time than the 3 AAA cells supplied. The lithium cell is a bit slim for the torch barrel, but it settles in when the end cap is tightened down. I would have given it the extra star except that it won't show Smartwater markings. For all the other UV uses it seems fine.


Thanks for your review, yes you do need a 365nm UV wavelength for SmartWater, this particular torch is 395nm.

Robust and well made

Great torch/ well made/ good delivery/ very pleased with it.

Superb Addition!

Another great purchase from torch direct! Professional service. Quality Products. Every Time!

Well I couldn’t make my mind up which wavelength of UV light I wanted, so bought this alongside another!

Solid construction, smooth focus! Fits in one hand easily and chunky design. Will stand on either end. Lanyard hole. Takes 3 x AAA in the standard Cartridge type holder. Batteries Supplied.

This 3 watt UV torch is amazing! Gives a great flood around a room when fully “Zoomed in” and focuses to a spot when fully “Zoomed Out” (But doesn’t focus sharply to the LED) This torch is powerful! Not quite sure how you would use the "Numbering" system on the zoom feature, but its there anyway.

When using this to check identification, I tested it on my (UK) driving licence, revealing the rose, daffodil, thistle and clover in “White”. You can see the outline of the road, but not as brightly. On the rear, you can see the crest and the tyre track, but not in "Colour" - If you buy the TK 566, the colour on UK licences is revealed.

Best of the Bunch

I have several mid-priced UV torches. This is the best I have used so far for identifying particles and fluids. A1

Good and bright, focuses nicely. Too early to comment on battery life, but metal body and solid build.
