Bicycle Mechanics - In need of new front headlight

I have a planet bike insight 15 watt rechargeable front headlight and it no longer works. I am in the market for a new front headlight and I would like one that is both bright, and rechargeable. Any suggestions are appreciated, Thanks.

I have this one. It has a rectangular beam with no hot spot.

I've an Ay-Up light that I love. Pretty robust little light, 100% water proof, 6 hour and 3 hour battery options, plus a great helmet mount option. Last I checked they're at 200 lumens. It's a bit cheaper to buy separate parts, instead of the kits unless you end up needing everything in the kits.
~$230 for a light, 3 hour (high) battery, charger, and handlebar mount.
$250ish for a 6 hour battery.

I think there's a fairly new Planet Bike 2W LED headlight with good reviews, powered by AAs.
I *really* like some of the 18650 rechargeable lithium battery LED flashlights using SSC P7 emitters, such as the current Aurora ak-p7-4: http://www.dealextreme.com/details.dx/sku.15740
$40 for the flashlight, about $10 more for a pair of good 18650 batteries (I already had a charger). Expected run time: about an hour on highest setting, about two hours on "medium" setting.

I've had a number of passersby comment positively on how bright the flashlight is when used as a headlight.

This has been my best experience. I have purchased several high end bicycle lighting systems and nothing gets more use than my $60/500 lumes flashlight kit from Asia. My high end systems' batteries died quick deaths, replacement costs are stupid high. My flashlight kit's batteries have lasted forever, I assume because the cells are charged individually instead of in series.

Niterider's Mini-Newt 250 is a 250 lumen one-piece rechargable LED headlight that can recharge from an AC adapter or an included USB cable. It's pretty low cost for its power and utility selling for about $120 complete.

Details? Where did you buy it?

If you've been riding with a 15W halogen, look for LED headlights with ~350-700 lumens for a similar amount of light output. These generally go for ~ $350.

A lumen is a measure of total light output independent of focusing vs lux which is measure of intensity at a spot in the beam. A low lumen light can produce a high lux if it is focused to a tight beam or has a hot spot.

The exact model I purchased is long gone, here's the website:

This Serfas True 250 ($129) works great for my commute. There are no wires that go on the bike, just the light, the rechargeable battery is inside. It can be recharged on a computer's USB port, or you can plug it in to a wall outlet for a quick charge. The light has four brightness settings and a blinkie mode. It comes with a handlebar mount and a helmet mount. We have a hard time keeping this light in stock at our shop, we order several at a time and have sold out at least four times since we started carrying it in the early Fall-

The DealExtreme flashlight linked in my post above claims 900 lumens, but according to comments and its specs on current, probably "only" gives about 500-600 lumens. It's hella bright (pun intended).

This light is nearly a dead ringer for the NiteRider Mini-Newt I mentioned above and goes for the same price.

Yep, I think I may have seen another brand as well that's essentially the same thing. Probably made at the same place, with slight differences, and branded accordingly. Regardless, they are excellent lights for their small size/light weight, respectable performance, reasonable price, etc. We had a sales rep come into our shop in the late summer and demo these lights, and we immediately ordered some. As I said earlier, the biggest challenge we've had is keeping them in stock. They're easy to sell because there are two or three of us in the shop who use them on our own bikes, and we're genuinely enthusiastic about them and I guess it shows-
