I'm looking for an advice regarding headlights for night time
commuting because on Tuesday a battery for my 3-year-old ViewPoint
headlight finally expired. Before buying a new battery, I would like
to explore other options. I'd rate importance of different features
to me as follows: being seen 60%, road illumination 20%, battery life
15%, weight 5%.

Looking through Performance catalog I found two interesting LED
headlights by Planet Bike: Super Spot (SS, and Dual Spot (DS). SS is
a single LED, steady mode for illumination, up to 30 hours battery
life with 4 AA batteries, sale price $30. DS steady and flashing
mode, up to 100 hours battery life with 2 AA batteries, sale price
$20.

Does anyone have a first hand experience with these headlights or
others with similar characteristics? I'd also appreciate any
interesting ideas on the subject.

Thank you, Victor

There are two kinds of lights: "to see by" and "to be seen" LED lights
are fine for the latter, seldom for the former. I use a Cateye EL-300
5-LED headlamp for my commute because the route is well lit w/ street
lights. As a "to be seen" headlamp, it's great. The odd color attracts
attention, and the batteries last a long time (30 hours). I wouldn't
even consider it, or any other LED headlight if I needed a "to see by"
headlight.

the new LEDS are better but still not very good to see buy unless you get one of
the better setups a couple companies sell in the UK.

Victor,

There's a good thread about this going on over at rec.bicycles.tech.

Here's a direct link:

I use LEDs for the lighting on my cargo trike:

I bought a gelled lead-acid battery from this industrial supply
house ( http://www.rpelectronics.com/ ) last year when my old one
died. The six volter cost me about $40 Canadian with shipping.
I commute year round on very dark roads and depending on the season I
have to be able to see the icy spots, potholes and the occasional
moose (rural New Brunswick). My 10 watt halogen light works fairly
well.

If you commute, visibility and vision are 50/50, cost and weight and
battery life are non-factors if your safety is concerned. Why would
you risk not being seen by a driver on her cell phone or failing to
see that pothole just so you can save a few dollars? You wouldn't
drive your car with only one headlight or with all of your taillights
burned out.

For serious commuting, in addition to proper clothing that might might
include some IllumiNite fabrics or AlertShirts, that means fore and
aft flashers, side marker lights, a head light, and a helmet lamp. For
me, that's four ultrabright 5-LED red flashers from Cateye on the rear
and sides, two Cateye ultrabright white LEDs in front, and a very
expensive NiteRider HID helmet mount. The front LEDs do a good job of
lighting up the road immediately in front of the wheel but it's the
helmet mount that gets me safely to and from work. And, because I've
dropped the HID once (a $90 light bulb!!), I carry a spare headlight,
my old 6v halogen; hmm, it's also a Cateye.
You can get by with fewer units, sure, but why? It's fun to shop for
bike lights these days.
Do I look kinda silly? Not really, I look like a serious bike commuter
who insists on being seen.
I often notice drivers noticing my lights and I have avoided glass or
some other hazard uncountable times.

I buy my AAAs and AAs at Costco in bulk and recycle the wasted batts
at my pro camera shop.

IllumiNite does not work well at all. I was sure disappointed in it.

why would you need a helmet light and a headlight?
there comes a point where more light does not do any good. because it is not
just how much light but that the diver will actually see you. a lot of drivers
are blind to anything but cars and no amount of light will fix that.

I can see a light on each side and one in the back but why do you need two in
back? get the new cateye http://www.bikeforums.net/showthread.php?t=68186

this has two separate lights for back and LEDS on each end too. all in one
package.

two LED front lights and a HID? that's a bit much. I use a flashing light in
front and a powerful headlight to see by. but I really don't need the flasher as
the headlight is blindingly bright.

no rechargables? man what a waste with all of those lights. you must be rich (G)

I'm buying a couple of 3 watt LED emitter (think 30 LEDs packed into one
bulb) flashlights from electrolumens.com. One on the head, one on the bar.
A head light is good to get drivers attention with, and spot things like
wildlife along the road.

1. A 3 watt LED is going to be about as bright as a 5 watt halogen - plenty
bright for commuting.
2. It uses AAs.
3. It is power regulated, meaning a pair of rechargeables is as bright as
brand new alkalines.

It will last plenty long for my commute home, and unlike a bike light,
popping in freshly recharged batteries is a snap.

depends on your speed I like a minimum of 10 watts and prefer more. soon we
should see LEDS that will replace halogen lights. there are a couple companies
in the UK that have good units but nothing in the us.

I use a five LED white flasher on my helmet in addition to the
Halogen front lamp. The helmet lamp can be pointed towards the
oncoming car (usually at a sideroad) to (hopefully) get his attention.
He might not see the halogen lamp but the flashing lights usually do
the job.

my halogen lamp is so bright and covers so much area I don't want to aim it. I
blind enough drivers as it is (G) even a cyclist coming down the cycling path
had to squint (G)

I've used anything from 2 to 20 watts. Like the manufacturers, I consider 5
watts the bottom of a decent commuter headlight, depending on conditions.

I would have to say that 5 watts on your head is worth much more on your
handlebars, because you can point it at the questionable spot in the road
ahead, or at that driver you aren't sure has seen you.

There are already LEDs that compete equally. Look at elektrolumens.com.
I'll be using one of them as a helmet light, and putting my 5 watt halogen
on the handlebars.

but they are not really cycling lights. it take about 3 3 watt LEDS to give some
decent light. so far only a couple places in the UK are making them.
