What's the beam shape like with that lens?
I've noticed that one of the weaknesses of many of the cheap LED lights (& some expensive ones!), especially from new entrants to the market, is that the designers have gone for raw power, & not worried about beam shape. Some lower-powered lights from firms which were making them in the days of filament bulbs, when every lumen had to be made to count, can look brighter, because they're putting the light where it's useful, instead of illuminating the sky, trees, your front tyre, and so on.
I have a 400 Chinese lumen Magicshine, which is probably no more than 300 real lumens. It's plenty for road riding, & I often use it in low (120 CL) mode. Big flood of light. My Light & Motion Stella 120 is a lot better at lighting up the road than the Magicshine on low, & even on high the Magicshine wins out only because of the sheer quantity of light But there are lights out there which beat the Stella despite putting out no more, & perhaps less, light.
A modestly priced lens which gives a cheap Chinese light a good beam shape is an excellent idea.
Any contact details for the UK supplier? I want two.
