The HID lamp throws a wicked amount of light and remains a favorite, but I don't think the HID bulb is as robust as the new LEDs that theoretically last thousands to tens of thousands of hours and are relatively impervious to the bouncies and on/off cycling. I worry not only about the HID failing but how long it would take to replace a blown HID bulb in this obsolescent unit, so its now on my helmet (OMG, the H-word!) rather than being on the handlebars and therefore subject to more road shock.
Bottom line is the lumen per dollar value is definitely going way up; not to mention, bulk going way down. Any of these individually will provide a lot of light at fast bicycle speeds and increasingly, not break the bank. With the Light and Motion Cub on my helmet and the two LED lights mounted on my two commuters, the headlamp can be aimed where needed (such as flashing motorists at side streets, checking for deer crossing the road, or just pointed up the road) while the bike handlebar lights point where the bike is generally going.
This ain't an endorsement of these brands above all others. Just what I happen to have bought. Bottom line is with winter and short days coming upon us, you better think about lighting if you are going to commute to work.The Trinewt at 500 lumens used to cost about four hundred dollars plus. The 650 lumen Lumina is now about 140 bucks and there are good LED lamps pumping out hundreds of lumens and costing less than a Ben Franklin. A lot cheaper than a typical ER visit. And as Steve says, there is plenty else out there. Just found this at Amazon. 1200 lumen for forty five bucks.
