Things are getting a little more serious with the SL-4, with 14,000 lumens to command, its starting to get real. You will be given a full curtain of light right in front of your vessel. Remember you can t steer yourself out of the light curtain so sit back and relax. Marker buoys will glow so bright you can see them better at night than during the day. Its very relaxing when you can see the markers over a quarter mile in front of you. Don t forget, this is fully dimmable, so approaching vessels will not be blinded. At 2 inches tall 12 inches wide, this light can be mounted anywhere in any orientation. Like all our lights this is a fully machined product that was engineered to thrive in the marine market.
