Smudges Lumenator Seems a good un

How do you reckon the 2013 Hope R4 compares to the Lumenator? Those are the two on my list ATM as I don’t really want to spend much more than £200. Not interested in loads of cheap lights as I can’t be bothered with the faff, I only use one light, and I like stuff that’s well made and reliable

My only experience of a Hope R4 was Mugboo off here had a vision 2 upgraded by me
and he also had an R4 which he requested I make brighter as the vision 2 was drowning it out and he now seems happy with the boosted R4

Does bear a resemblance to the Vision 2

But fingers crossed without the failure rates I’ve had with both my Hope lights.. 🙄

trout, what did you do to the R4, how much did it cost, and what difference has it made?

the R4 got a new driver board that would let it drive the XPGs to the full 1.5 amps
And a new switch
Parts cost. £25
Labour about 1.5 hours

Not sure on the difference have to get Mugboo to comment on that score.

Hi there,
I just joined the forum being interested in the bike lights.
Somebody says:
low = 0.280 amps = 2 Watt
med = 0.960 amps = 7.1 Watt
hi = 1.40 amps = 10.36 Watt
boost 1.85 amps = 13.7 Watt
At these power levels at input, with 88% efficiency on the driver it turns to a max of 12 Watt on the LEDs. This means 1200 lumens at most. Remember that Magicshine 880 really draws ~20Watt from the battery, for a max of 1600-1700 lumens. This light has the ability to output 2000 lumens based on the LEDs spec, but seems to be far from that, and the reason is heat dissipation. It’s too small to dissipate the 80% of power turned into heat (at max setting about 11.3 Watt is heat, 9.6 Watt from the LEDs and 1.7 Watt from the driver). Anyways, looks like a good and compact light. Maybe with some tweaking (current limit increased little) it can output more, like 1600 lumens.

I love my little Lumenator. If you want to make it even better than get a Hope Universal Light Mount for it. Lovely.

Seriously thinking about hitting the buy button on one of these. Think it may be perfect for soloing at Mayhem.
