I have bought a few of these over the years and I still think they are the best keyring torch available. The latest version now has 47 Lumens and is very bright indeed.
I found that Torch Direct had the best price I could find in the UK and delivery was very swift. I have no hesitation in recommending this small but mighty torch.
Pops on and off to turn the mini maglight's bright white light completely red. The red light is inevitable much fainter than the white light, but it's exactly what I needed for use at night while keeping dark-adapted vision.
