Your property's lighting, on one order form
Maintenance teams lose hours matching old lamps and ballasts, and a wrong part means a second trip up the ladder. We build a custom order form for each property: the exact lamps, ballasts, drivers and fixtures installed on site, with photos, so anyone on your team can reorder the right part from a phone. More than 720 customer accounts already have one.
- Right part the first time: correct base, pin configuration and color temperature
- Your pricing and live availability on every line
- Janitorial, safety and maintenance supplies on the same form
- Net terms available on approved credit
- No charge to set up. We start with a job walk (virtual works best), and most forms are ready about two weeks later.

Vendor information
Certified Lighting Specialists, not order takers
Our Lighting Specialists are certified by the National Association of Innovative Lighting Distributors (NAILD). In practice that means they can identify a ballast from a half-worn label, tell you whether an LED tube will work on your existing ballast, and flag a color temperature mismatch before it goes up in a hallway.
Call or text 949-589-3020 with a lighting question. You will get a straight answer.

California's Fluorescent Ban: What Maintenance Teams Can Buy Now (2026)
California's AB 2208 ended sales of fluorescent tubes and pin-base CFLs on January 1, 2025. What's banned, what's still legal to use, and the LED replacement for each lamp type, including how to choose Type A or Type B tubes.
How to Find the Right Fluorescent Ballast (and When to Skip It)
Match a replacement fluorescent ballast from the old label: lamp type, number of lamps, voltage, starting method and ballast factor. Plus how to tell a bad ballast from a bad lamp, and when a Type B LED tube is the better buy.
Understanding LED Drivers: How to Match a Replacement
Constant current or constant voltage, Class 1 or Class 2, wattage headroom and dimming: what to copy from the old driver's label so the replacement doesn't burn out your LEDs.
