Friends, VOLT linear LED Hardscape Lights are the best in the industry. They feature high quality CREE LEDs (with tight binning) for consistent color and brightness. LEDs are mounted close together to eliminate hotspots. And, they have bi-directional mounting holes to allow both vertical and horizontal mounting. All-in-all, excellent pro-quality fixtures. To provide these great lights with even more control and flexibility, we now offer glare guards designed for each model. Since linear LED lights are usually installed under overhangs, they don't typically need additional glare guards. There are, however, situations where direct glare can be a problem. Here's some examples where the additional glare guard comes in handy: When hardscape lights are installed along the side of a staircase - such as under railings or capstones. When hardscape lights are installed under capstones on very tall retaining (or freestanding) walls. Or, when these walls are on an elevation. When the hardscape lights are used for horizontal or angled mounting. These new glare guards are offered as options when you purchase the hardscape lights.
