Speedy…….

Thank you very much for the help and patience from both Stewart and Meg. The items arrived so quickly - Christmas has come early.
The service at Torch Direct is first class.😊

Needed to be shown the light

Spoke at length with Stewart on getting the right product for me - Beam distance & Flood. Had to go over my budget but we managed to strike a happy deal & the FENIX LR40R is now on it way to me

The only area light you will ever need

I cannot speak highly enough of the Nitecore NWL20. One of the key features that places this above many others in the field is the replaceable battery. This means for example, that I now carry a spare battery in a battery case which increases the time the light will work up to around 16 hours. It was this particular feature that led me to buy 2. I have found the NWL rugged and reliable, with no indication that will change any time soon. A number if its positive features are shared by other area lights (the magnetic base, carabiner clip on handle, fully adjustable etc), but principally the ability to extend run time pays dividends and sets the NWL20 above the competition. Service from Torch Direct was, of course and as always, faultless.

Nitecore NWL20 Rechargeable LED Work Light
A slim and well made torch

The Olight i13 Plus penlight was a spur-of-the-moment purchase, seen when viewing the latest arrivals. It is a very well made torch, interesting to use - press the “on” button until it clicks and the light is dim. Press the button twice in rapid succession and the light is very bright, ensure that you have pressed until the click is heard. This way of turning on the light takes a bit of practice but is effective. The body of the torch is slender - it takes 2 AAA batteries - and has an attractive design over the body length, rather than a standard knurled finish. Mine has my initials laser etched into it. This is a useful torch for clipping inside a pocket.

Olight i3T Plus LED Penlight

Effective, efficient and value for money supplier, just a shame they rely on UPS as their delivery contractor as they are utterly unreliable and frustrating to deal with, failing three times to actually deliver my order despite informing me that they had actually tried when they hadn’t!

Another excellent product

Super company: reliable, great service and super communication throughout. I wouldn’t buy a torch from anywhere else.

Maglite ML300LX 2 D Cell LED Torch
Robust Torch

Nice chunky torch easy to handle even with gloves that has a good light spread. Ex rated is necessary at work and the engraving makes it clearly identifiable as mine. Not too hard on the batteries is always appreciated. Arrived quickly and was exactly as described. Can’t fault.

Unbelievably great torch

Fantastic quality led torch like all Maglites. Exceptional brightness. Very nice design and helpful attachment you can put on it to clip on pocket/belt if required.

Stephen G.
Maglite MAG-TAC Plain Bezel Rechargeable LED System
Simple and effective.

The best torch is the one you have with you when you need it. This is my second Mini-AAA (the first lives in the car). This torch is so light you can forget you are carrying it until it's needed. The switch mechanism is a simple twist, beam range is amazing, run time excellent. No multi-mode nonsense either.

Bought this lamp a few days ago. I am so happy with my purchase I bought two more as Christmas presents for two friends. Good buy, thank you.

Brilliant torch

Love the torch. A good size and lightweight too.
Brightness is amazing! And battery life is really impressive.
Having to remove the battery and charge the physical battery is odd, but it isn’t an issue. Very easy to do.
Overall a great torch! Very happy.

Fenix TK16 V2.0 LED Torch
Decent Weight to performance.

For the size and weight, this headlight delivers with very well-thought-out modes. I have the extra battery pack for back up, but on the whole I use the Headlamp as is. The second light setting I use the most and it lasts a good long time. The red is easy to use on the buttons, perfect for camping. The best yet for me, and I have plenty.

Great torch for professional use

I knew that having a good torch was essential to my job but I didn't want to spend loads of money. This torch packs a punch and has a very handy clip that keeps it safe in my pocket when I'm leaning over railings and climbing ladders. The powerful beam helps me to identify leaks and other issues that an inferior torch wouldn't show up. I'm happy with the battery life. Despite working an 8-10 hour day, I only use the torch for a a couple of hours total
