<strong>630 </strong><br />
This lamp does the same thing as the 610 but is more compact and has a composite body that's black powdercoated. The 630 has a plastic composite body that's impervious to cold weather and rust. If you're looking for a foglight or low-beam helper, decide between this one and the ZE-1. The ZE-1 is a little more broad, but the 630 has slightly more range. Sizewise, it's 5 1/4 (h), 4 5/8 (w), and 2 1/2 (d).
