Almost went for Troutie's mini light as I want a helmet mounted death beam but I'm still umming and erring.

The pros and cons seem to be:

Troutie pros:
Newer LEDs
Everyone here rates them
Possibly brighter?
Has a medium mode – 4Fourth only has low or high

4Fourth Pros:
Smaller
Lighter
Cheaper (£195 vs £250)
Same(ish) brightness
Run time a fair bit longer (3.75hrs vs 2.5 on max)
Possibly more suited to helmet mounting? The mount looks more sophisticated.
They got back to me very quickly when I asked a few questions – Trout hasn't yet but to be fair, I only sent the email last night!
Lipo batteries used by 4Fourth are possibly better than Li-ion ones?

So now swinging back to 4Fourth.

Can anyone help with anything more than just "Trouts are better?!"

Well, soon, I expect to be able to offer a helmet light.

Latest LEDs, XP-E or XP-G
3 light levels
QR
Bar, helmet or head mount.

Trout is on holiday at the moment.Loving my mini it is fantastic,
everyone who has seen it has commented on brightness/build etc.

Luminous – how soon? Any rough specs/costs?

I need to be patient and gather all the facts. Not a strong point of mine!

Anyone got a URL for 4Fourth?

go for a troutie…………you know it makes sense

hey up Matt
got your mail and replyed this morning though I am in tenerife and have shonky inet access
but it did say message sent.
there is a demo out there and I can get the last guy to borrow it to forward it to you for a try if you want.
though it is an early one so only hi low

Thanks for the four4th link – the XPG version of their light reviewed on muddymoles looks the business.

Trout – sorry I didn't realise you were away.

No hurry – more than happy to try one out when you return.

New USE Diablo?

Not bright enough but a good call nonetheless.

I like the mole review… basically any light with this kind of power is going to blow your mind on the trails.
I like my four4th… but only have 8 year old lumi's to compare… and there is no comparison.
Two modes is fine on a helmet light as you don't want to reach up and fiddle often. Low mode is good enough most of the time, high is for singletrack… job done.
