Currently running a Fenix p3d but already thinking about my Christmas present.
Would a USE Diablo or AyUp ultralight be noticeably brighter?

Have a search on here.

At teh cheap end of the market a magic shine or DX torch or a similar light from a UK resellor such as smudge. £30 – 70 for 5 times the light of your torch

At the expensive end trout or luminous lights. Hundreds of pounds for 10 or 20 times the light from your torch

I tried one of the Smudge (www.mtbbatteries.co.uk) XML T6 lights for the first time tonight.

Perfect helmet light. I had it paired with a 3 x xpg light – LightandGo Fireball (pretty much the same as the Magicshine mj-870. The XML is very impressive – way more throw than the Fireball and loads of useful spill of light nearer to as well.

Considerably brighter than my Magicshine MJ836 I had before. Also seems to be much easier on the battery – more than 50% left after a 2.5 hour ride, the P7 based light would have used a lot more.

Just got What MTB and looked at their light review.
They loved the Ay Up . They quote higher output for them over the Diablo but the Diablo picture is brighter.
Am I missing something?
Also are the Ay Ups going to be subject to import taxes? I must be on some kind of black list as I always get stung for every tax going.

Am I missing something?

yes – the ayups are not as much light for your £ as the stuff I mentioned. a nice neat light mind you

I just bought one of these for helmet mounting.

where as i bought one of these for about £13 + helmet tourch mount from ebay for £4……
