I enjoyed your test, Dan, but this last bit is misinformed. If you
had a hub dynamo, for a hundred bucks you could get a BUMM Fly or
Cyo at the front (or perhaps even a Phillips Saferide, which is a
superior lamp) and a BUMM Toplight Line Plus at the rear, and then
you would have what many consider the best lamps in the world, with
no further cost for batteries. Here's my installation of specialist
versions of the lamps I mention, complete with light-throw piccies:

installation would of course use a hub dynamo and the 6V version of
these lamps.

The advantage of Dan' lights is that they are easily transferred to
different bikes.

So is the Busch and Muller Ixon IQ, which runs on 4 x AA NiMH cells,
and gives 5 hours on high (only necessary of unlit roads),

That is another marketing 'lie'. I have one and it runs max 2 hours on
high of which the last half an hour dangerously low for unlit roads.
Again I was disappointed in the battery life of a battery powered light.
Plenty of light but only for a short period of time that is the deal.
Charge before every ride, that sucks for me.

20 hours on
low power (fine in town)

Also not true.

or any combination of those.
Extra mounts are available so fitting to different bikes (or an
alternative position like the fork crown) is a doddle, and with a ride
& charge adapter cable you can even run it (and charge it) from a
dynamo if you fit one later.
It's the same emitter and optics as the Cyo.
The mounts all have lateral adjustment as well as vertical.

That part is true.

Peter White lists the run time on low as 13 hours, and high at 6 hours.
Users that have done actual tests have gotten around 5 hours of run
time, and not with the highest capacity NiMH batteries available. So if
you got only two hours then something was wrong with your batteries.

It's not a suitable light for commuting for other reasons unrelated to
the run time.

There is nothing wrong with my batteries. Did a test tonight. Fully
charged, original charger, original batteries with only a few charge
cycles. At room temperature of 21 C on high after three hours the
amount of light sank to a pitiful level, hardly enough for a to be seen
light on well lit streets. I don't believe what Peter White list or
what other people say if I have my own observations. 5-7 hours on high?
No way.
