I guess it’s down to what light is ‘best’ for what you want to use it for.
The Inton light is a pretty big light and it’s really only suitable for bar mounting as it’s quite heavy but it throws out a huge distance with it’s large twin reflectors and has amazing heat management due to it’s size and weight.
The Gloworm is a much smaller and is perfect for use on a helmet or bars as the light head only weighs 80g and is little bigger than a matchbox. The Gloworm doesn’t use reflectors but uses optics so has a larger hotspot at the expense of some throw compared to the Inton. It’s optics can also be interchanged between Spot and Flood to suit what sort of light output you desire.
The Gloworm is a more sophisticated package and probably more flexible as you can mount it on a helmet, bars or head strap harness plus it has 4 different operating programmes to suit what it’s being used for – Commuter, Trail, Adventure, Bush modes. Compared to the Inton it also has a longer warranty, uses better quality Panasonic cells in the battery pack and is IP66 rated for waterproofing (being tested for IP67).
The Gloworm is the one I had some people test on here including Mrsmugsy who won her 24hr race with one.
There is not currently a new ‘secret’ brighter light around the corner.
