30 x high intensity super flux LEDs encapsulated in a weatherproof casing. At one metre the Astro will give you a light reading which is the equivalent to a 10w halogen bulb, but uses 5 times less power compared to a halogen of this wattage, so it can be left on for much longer without draining the battery.

Voltage range: 10 - 16 volts
Power Consumption: 2.2 watts
