Apart from that, this torch is very solid and well made. It feels like it would be enormously difficult to break. It isn’t particularly waterproof, however, though it will work in the rain. The MT14 comes with a carry case that, like the torch it’s designed for, is exceptionally hardwearing and well designed. Many modern devices are referred to as being ‘waterproof’ or ‘water resistant’, however, it is worth noting that every device has a point whereby water can get inside and ruin it . It could be the temperature of the water, the length of exposure, the depth or even manipulation of the device while it is submerged, but whatever protections the device may or may not have, water ingress always holds the potential to cause irrevocable damage. If using a hand-held torch is part of your job, you’ll know that there is no better option on the market right now than an LED torch. The brightness of zoomies can also dim considerably when the light beam is at maximum zoom in either direction. Zoomies are also at a greater risk of water ingress, since the head adjusts like a camera lens.
This torch is lightweight, yet strong and (reasonably) weatherproof to boot. The runtime is pretty great, with power lasting up to 130 minutes on ‘Turbo’ mode.Now, this definitely can be useful, because it means that the torch can still be in play even as your spare batteries are charging, but it also means that you’re more likely to need to buy extra batteries. As a result, this is far from the most cost-effective choice out there. Throwy ‘ beams throw up a long-range light with a tight hotspot, like a spotlight. Not especially suited for close-up work, these beams are very good for seeing people or objects that are relatively far from the viewer. They are also very good for lighting up dark tunnels and caves.
On the negative side, the torch’s long, thin design does not make it particularly compact or easy to store, in fact, it has a tendency to get in the way. A standard D battery might produce a current of around 10,000 mAh (milliamps per hour). As the name suggests, a milliamp is one thousandth of an amp. How long the battery lasts, then, depends on the device’s current consumption rate. The switch , which can be located almost anywhere on the device, is the element that completes the transfer of energy from the batteries to the bulb.In terms of outer design, there are small, portable models such as penlights, clip and keychain torches. There are also right angle torches (which are often adjustable and used for hands-free work), flexible torches (which are good for a variety of uses and positions) and body or head-mounted torches. The Ledlenser MT14 will work well – and in most weather conditions, too. The beam is nice and bright, though not as far-reaching or bright as some others we’ve seen. The battery life and charge times are both superb and options such as a customisable energy saving mode are excellent additions. Smaller LED torches, of course, will use smaller batteries (with AA and AAA being the most popular). However, we will be focussing mainly on D batteries for this section.
Misell’s invention would not have been possible without the prior invention of the first dry cell battery (by the German Carl Gassner in 1888), so the inventions of both the battery and the torch go hand in hand. Overall, it is definitely fair to say that LED torches are significantly better than most, if not all, other options. How Long do the best Torches Last?You should also avoid mixing battery brands if possible and never use batteries that appear to be misshapen or dented. You might also consider switching over to rechargeable NiMH batteries, which are far less likely to leak. If we imagine ourselves to be unscrewing the head of the torch and peering inside the case, we will see the batteries. How Does a Torch Work? Then, in the early 1960’s, Losev’s observations inspired Americans Robert Byrd and Gary Pittman to create the first LED (an infrared version not visible to the naked eye) as a by-product of their search for an LED laser. Feature a design well suited to the tasks for which it will be used (i.e. body mounts or portability).
Battery life may vary from torch to torch, but the LEDs are still the longest lasting form of man-made illumination there is. A good torch should, if well kept and looked after, last for many years. The Components of a Torch LED, as you probably know, stands for Light Emitting Diode . An LED is a semiconductor light source that reacts to electric current passing through it by emitting a bright light. Floody ‘ light beams illuminate a wide area, but do not throw light over particularly long distances. This type of torchlight is very useful for lighting up an entire darkened entrance or room, where longer-range LED torches will simply illuminate whatever specific point they may be directed toward. This is a good type of light for head torches and anything you need to see close up. An IP rating features two numbers from 1 – 6 (‘0′ or ‘X’ means that it has no score and offers no protection). The first number describes the device’s ability to resist dust, dirt or small objects. The torch emits a pretty bright 1150 Lumens, which boasts a maximum throw of over 135metres. It also features an upgraded TIR lens that produces a perfectly balanced beam.
The Ah rating is really only used to compare products, however. It is not a reliable measurement in most other circumstances as every device is different. There are a lot of different types of LED torches in use today. These include rechargeable models, where rechargeable Lithium-ion batteries replace traditional batteries. The bulb (or ‘lamp’) is the area at the front of the torch that emits light. This can be a tungsten filament bulb or an LED bulb. The shiny area around the bulb is usually called the reflector . The reflector is fashioned from plastic and coated with a shiny layer of aluminium that directs the light rays forward to create a steady beam.
