I'm dropping it at Si's today so he can compare it with his standard light. No doubt he'll post up a beam shot.

Right, I do have the Hope R4 that Trout modified. I had a quick ride last night with it but I can't do "proper" off-road as my hand is in a cast still, but the modded R4 is considerably brighter than my standard R4. I struggled to find anywhere dark enough or not overgrown to take some beam shots so went home and did them in the back garden which wasn't ideal as you can't gauge how far the light is travelling. (Tyre swing is approx 12m away).
The throw of the beam was what disappointed me about my R4. I bought it as a helmet light and it was poor in comparison to my old halogen MR16 30w Philips ES running on a big 14.4v battery.

Anyway here are the photos.

They have apparently changed the drivers in the 2013 model - only change I can see is a slightly revamped trail setting and, according to Hope, slightly better battery life.

Troutie - any development with the all in one unit?

I have had both V2 and V4 upgraded and the difference is amazing. As Chris says, you do need airflow over them to keep on new high power settings but even on recent balmy nights ( amazing but true) normal mtb speeds allow unit to stay cool enough- in my experience only dim out if stationary and forgot to dim down.
V2 upgrade is brighter than original V4 and half the weight

I have not over come the heat just the new driver monitors and dims if it reaches a preset level .
the light can only handle full whack with lots of airflow .
but it also can have either five or three levels on the three. level 2 will I think be similar to full on the stock light.
on full
Just waiting for Jason to report in his impressions of it in the dark.

It was a quick job and I did not get to do the before and after beamshots which I like to get.

Trout - how have you overcome the heat problem when cranking the output up?

Just a note to those looking at R4s.

A 2 cell battery version of the Model 401 will be available soon.
An extra 400 lumens, same price, with battery level indicator.
