On January 1, 2029, fluorescent tubes and CFLs come off the shelves in Washington — and Clean Buildings compliance deadlines start hitting large commercial buildings in June 2026. If your building still runs on fluorescent lighting, the smart money retrofits on your schedule, not the deadline's.
Plan the upgrade. Don't get caught by the clock.

What HB 1185 actually prohibits, what's exempt, and why "we'll just stock up on tubes" is a plan with an expiration date.
Occupancy, vacancy, and daylight-responsive controls — what they do, where the energy code wants them, and what a retrofit actually involves.
Fixture-for-fixture swaps, tube conversions, and full redesigns — matched to your building and budget, with utility rebates factored in.
Daylight zones, photocells, and automatic dimming that satisfy the energy code and cut the bill at the same time.
