SL21 Up Light: Purpose-Built for Power and Precision

By Patrick Harders, LC

When you hold the SL21 Up Light in your hand, you will immediately know it’s not your average up light. This luminaire reflects the best of our design philosophy: heavy-duty, high-output, and intentionally engineered for real-world use. It’s built with precision and designed to deliver consistent, powerful performance in the most demanding light commercial environments.

The First Thing You’ll Notice: The Weight.  

At over six pounds, the SL21 is forged with solid brass and held together by a through-bolt assembly. I designed it entirely with our in-house team, never outsourced to a third party.

When professionals open the box, it’s immediately clear they’re dealing with something built to handle real work in the field. That reaction speaks to more than just its weight; it’s the confidence that comes from knowing it was built to last.

When to Use 

I recommend the SL21 Up Light in scenarios such as:

  • Commercial installs with exposure to foot traffic or equipment

  • Tall architecture or large trees that require higher output than a standard up light

  • Multi-story Residential where the client expects a dramatic impact

In other words, if you’re designing a project that needs strength, intensity, and reliability, the SL21 Up Light should be on your shortlist.
