Vector's 1 Million Series light gives you the bright, tight beam that only a halogen bulb can provide. In terms of reliability, the VEC's anodized aluminum body and sealed battery make this an extremely durable product. Plus, it's rechargeable, and it has a battery status indicator so you'll know when it's time to plug it back in. A three-position dimmer switch allows you to use only the amount of power you need for the task at hand.
