New Sigma Hiro tail light?
 
Does anyone know if the Sigma Hiro tail light is 1/2 watt or is it 1 one watt?

It looks like it just came out so when I googled it there wasn't much info.

1 extremely bright, red High Power LED
2 modes-constant and flashing
2-stage battery indicator
Simple battery change
Long burn time up to 120 hours
Fast tool-free mounting
Batteries included( 2x Size N)
Watertight

You don't want N batteries.

I was thinking- what the hell is an N battery. Then I googled it. I've always seen them as LR1s in the alarm industry for very old wireless devices before the CR123 lithiums became common. I would not want those in a bike light. Too hard to find and though rechargeable might be available they would be a pain to find most likely.

I got some DX lights that came with them. The batteries lasted longer than the lights :)

Regarding watts... A 1W led driven at 1W will burn through these batteries in 2-3hrs.
As usual on blinkies that claim high wattage leds, the led wattage is irrelevant as the 1W or 1/2W leds are almost always underdriven.
