Video Transcript for Gustafson Lighting RV Lighting - Ceiling Light - 277-000487 Review

Today we're taking a look at the Gustafson RV recessed halogen light. This halogen light illuminates your RV's interior. It features a single bulb design which is easily accessible simply by removing the glass lens. This lens allows plenty of light to come through. It's not a completely clear design, so it's kind of like a frosted feature to it, and then the base of the unit is a durable metal construction that's white in color.Now, your installation requires a 3-1/2" diameter hole. The fixture is then held in place with these spring clips, and it does come with three mounting screws to get it installed.

So, you got the mount holes right there. Mounting hardware is included. Wattage is 20 watts. This is designed for 12 volt DC applications. I'm going to go and hook it up to power, then we'll also turn on our programmed lights so you can see it in a low light setting.Again, it features a single bulb design.

As you can see here, it sends out a really nice consistent signal, plenty of light output, and that lens does a great job at distributing the light output very evenly. And, that's going to do it for today's look at the Gustafson RV recessed halogen light.
