Food processing. Car washes. Parking garages. Anywhere that gets hosed down needs a fixture that can take it.
We sprayed the Citadel 4ft. in our IP66 chamber to show exactly what it handles. Hint: It passes with flying colors.

Will Baron, out at Goshen Valley Boys Ranch in Waleska, GA today. Volunteering.

Goshen Valley has been home to young men in the foster care system since 1999. Family-style homes, dedicated houseparents, 160 acres of north Georgia countryside. It's actual hard work that changes lives.

When the chance came up to back kids who got dealt a rough hand, Will said go. So did we.

Tons of clamping force. Robotic arms. Polycarbonate and acrylic, shot under pressure.
The tool changes. The machine doesn't.
Today, Citadel lenses. Tomorrow, the next thing we engineer.

The SLP crew took on LEDucation with a curious eye and a full schedule. Smart controls. Human-centric lighting that's evolving fast. Seriously powerful industrial fixtures built from solid aluminum. A hazardous location fixture that had our team taking notes. The engineering on the show floor was sharp enough that our own engineers walked out with notebooks full of new ideas.

Off the floor, we reconnected with our OEM and supplier business partners. We laughed, celebrated wins, and sketched out ideas over plates of incredible Italian food at Carmine's.
Here's the thing. The fixtures were impressive. The conversations were better.

LEDucation is a reminder that this industry runs on people. Real connection matters, and SLP is strong because of the partnerships we respect and invest in. That's what lighting partnerships are all about.
