anyone used the Romisen RC-29 II R4 ?
I'm looking for a helmet light to accompany the magicshine headlight i have. Basically, i want to be able to look down at the cyclecomp and HRM and also look around corners.
Would need it to run 2 hrs on a AA NIMH
has anyone used this:
if so what's your runtime? Also, anyone know the lumen output?
The original was 100 lumens, the xpg model should be brighter at around 140-150 lumens.. For a helmet light the flood to throw option is very nice, you can really dial in the size you want.. I think there are 3 flood to throw models..
single cell AA light at that output will not give you 2 hours.. About 1 hour with eneloops 2000mah and 1:20 with Sanyo 2700mah cells..
Awesome, 1 hr is about enough and I can always keep a 2nd battery if need be. It's really just a light to complement my magicshine and allow me to see the cyclecomp and HRM so it should be plenty.
I'll look up the sanyos. I wonder if i can use my energizer charger with the sanyos or if i need to buy a whole new set...
The charger should work fine as long as it accepts NIMH batteries.. Some other good cells are Duracell 2650's and Titanium 2700 brand..
If you need a nicer charger that handles AA - AAA the La Crosse Technology BC-700 charger is one of the best..

this looks like a good deal: Going to pick these up. A few bucks more than the duracells but a better cell.
By the way, shining beam has extension tubes that will fit this light (to allow 2 AA batteries).
Note that the battery compartment is wider than a normal AA.
Put o-rings (or some duct-tape) around the batteries (the one nearest the head, especially) to keep them from rattling. (If the batteries rattle, the light can change modes).
The flood mode of this light is quite nice. The throw mode isn't so great (at the most-focused setting, an image of the square die is projected).
The throw of the following is better.
Oh, when the battery gets low, these start strobing.

Found this nice deal on lockblocks for anyone that needs some extras
can i use those for a helmet mount? Wonder if they're long enough. I have a little zip-tie system that works great...till i want to go riding in the day

Another nice mount is the zefal doodad plus, which is made to mount pumps to your bike.. Some bike shops stock these but easier to find online..
Picture below is Limar with zefal doodad plus..
The following is another source (slightly more expensive) for a 3 pack.

Just bought the 18650 version of that light, the Romisen RC-2R4 II R5 LED flashlight, should have it by the end of the week... Will give report on brightness and burn times.. It is rated between 250-350 lumens depending on batteries used..
Just a quick report back. The light was still going strong after 90 minutes with a 2500man NIMH.
It gets pretty bright at that time (7:30am) so it's hard to compare with the starting brightness, but it didn't quit. I got the Sanyo 2700s today. I might save those for my camera's flash since the energizers are doing so well..
