I confirmed these outputs, although high I measured a little lower at 240 lumens – but that’s still pretty good for a light this size and weight. This drops to around 50 lumens after 1 minute. Unless I state otherwise I’m measuring the lumens after 30 seconds, as per the American ANSI flashlight testing standards. It will also run off an alkaline or NiMH rechargeable battery. The manual forbids a battery with a voltage higher than 3.6V so you shouldn’t use a Li-ion 10440 battery in this torch either. A couple of minutes later, the light shut off. That’s not exactly the 90-minute total expected runtime, but it is close enough for me. They claimed a one-hour charge would completely recharge the light. I plugged in the light and in only 45 minutes, the charging LED went from breathing blue to green. Nice! OLIGHT quotes 90 lumens of output from its Philips LUXEON TX LED. I measured 114 lumens with an Eneloop battery which barely dropped even after a few minutes. More impressively I got exactly the same constant regulated output with an Alkaline battery – it held at 114 lumens for over 5 minutes. OLIGHT quotes 70 minutes runtime off a NiMH battery, and 45 minutes off an alkaline. OLIGHT don’t specify the exact LED used but I measured its colour temperature as a very cool 7251K without any noticeable unpleasant tint and with a CRI of 77.

The E03R also has a Everlight 2835 4 lumen red LED accessed with a long press with the torch off. Press the button again for a flashing mode. The red light is useful to preserve your night vision, and as an emergency beacon. Discover the power of illumination with the Aurora A8 USB-C Keychain Flashlight. This 4th generation device is the perfect tool to light up your life, with three unique functions – amber ( the amber light is used as a warning signal to indicate a potential hazard or change in situation, and to prompt individuals to take appropriate action.) and red/blue warning lights. Enjoy the freedom knowing you can light your way, no matter where your adventures take you! I did find the Eneloop battery quite a tight fit though – it’s easier tightening the head down to turn it on with a standard alkaline battery. After our fans repeated calls and long-awaited, in 2022, RovyVon finally brings the USB C charging port to the aurora series. Powered by a 330 mAh Li-Po battery, the upgraded A7 can be fully charged in one hour through the USB C charging port, it also supports USB C to USB C charging. R9 is an additional score that represents how accurately a light source reproduces strong red colours often found in skin colours, clothing and food. Again the closer to 100 the better but this number will usually be lower than CRI, often by a fair bit and can even be negative.The Duv value represents the tint of the LED. The closer this value is to zero the better, if you want perfectly neutral lighting with no tint. Less than plus or minus 0.006 would be considered neutral. A more negative value, often with a rosy tint depending on colour temperature is usually considered preferable to a positive value often resulting in an undesirable green tint. In any mode and when the light is off holding down the mode button takes you to the momentary 500 lumen turbo mode until you let go. When the light is off holding down the power button will take you straight to the 1 lumen ultra low mode. With this Eneloop battery it weighs only 19.3g and you can see its size on screen. It’s as simple as a torch gets with just one mode. Tighten the head to turn it on. The beam has a visible hotspot and in high mode has 580 candela of intensity equating to 48m of throw. It’s the lightest torch in this roundup at just 15.4g. In fact if you take the supplied keyring off it weighs an impressive 12.6g and it can still be attached to your keyring though the end hoop. I’ll have dimensions for all the torches in the roundup on screen as I discuss their build and weight.

The torch turns on and off with a half second press of the power button. When on, the power button cycles through the modes from a 5 lumen eco, to a 30 lumen low, a 80 lumen medium and a 260 lumen high. The last mode used isn’t memorised – it always starts in the 5 lumen eco mode. 260 lm high mode The white MATCH CA18 LED provides 441 candela or 42m of throw – it’s a very floody beam with not much of a hotspot and is more useful for close work. Seeing a display of the mode you’re in with real time information on how long you have left is just brilliant. From 60 hours in ultralow to 56 minutes in 200 lumen high mode. Turbo mode has up to 15 minutes but has temperature regulation and will step down when it gets hot.Like the Nitecore TIKI the modes are very well regulated and all the modes up to 200 lumens stay very constant. And I got at least the full 500 lumens in turbo for around 2 minutes before it started getting warm and dropping its output. Which is plenty since you need to hold your finger down the whole time anyway. Just as a comparison I carried out all these measurements with my iPhone 13 Pro’s torch. In its highest mode it produces 15 lumens, with an intensity of 8 candela which works out as a throw of just under 6 metres. Its colour temperature is 5263K with an impressively high CRI of 95 and a neutral tint.
