Received my Lumenator on Saturday – thanks to Smudge for a speedy service. Quality of the light appears good and though I haven’t had a chance to try it in anger yet, light output is something else compared to previous lights I have had. It’s also a decent beam pattern with a good spread of light. The light unit is very compact.
I’ve mounted the light unit on the handlebars and the battery pack, after a bit of shopping around, in an extra small Topeak saddle bag (with the battery removed from it’s OEM woven nylon bag): http://www.evanscycles.com/products/topeak/aero-wedge-with-straps-extra-small-ec008237 . It’s very neatly strapped tight up under the saddle. The straps have decent buckles fixing it to the saddle rails rather than velcro, which is a bonus. For anyone that needs to know the battery pack is 7.5cm x 6cm x 4cm. Pack is rubber coated and cable exits through a sealed grommet in the end. It appears to be very water resistant.
I’ve handlebar mounted light unit with a Hope Universal Handlebar Mount which means I can position the light where my handlebar starts to kink near the stem without any problems: http://www.chainreactioncycles.com/hope-universal-handlebar-mount/rp-prod23533. The screw that comes with the Hope mount is too big for the Lumenator, as others have said, and the size it needs to be replaced with is M4 x 10mm.
The cable length between the light unit and the battery is about 125cm. I’ve run the light cable attached to brake and gear cables under the top tube. I want to be able to remove the light and battery quickly and easily so instead of the ubiquitous zip ties I am using 5 black coated wire ties. I’ve also used one of these M:Part adhesive cable guides I had lying around on the side of the frame just below the seat post to help run the cable vertically for the last bit to the seat pack: http://www.sjscycles.co.uk/m:part-self-adhesive-cable-guides-3m-pack-of-3-prod13059/ . Fortunately the light cable clips into the jaws of the cable guide quite nicely without the need for a cable tie.
All in all a very neat light and what turned out to be a very neat install.
