Many of our Title 24 clients have been asking us whether they can safely specify LED fixtures that would qualify as “high efficacy” lighting under Title 24. Could one conceivably create an entire lighting plan for a custom home using mainly LEDs, and if so, would it pass Title 24? Would it look any different to the untrained eye? Would it actually use less energy? Or, are LEDs better used as a supporting component in a diversified lighting plan rather than as the main workhorse? Are LEDs sustainable to manufacture? Do they use less power in a real-life installation, not just in the lab?
The answer to LEDs in California is a qualified but definite yes. There are definitely products out there that will comply with California’s energy codes, and we should see more coming to market this coming year. The issue is not the LED lamp itself, but the housing, because the fixture’s efficacy depends on the entire assembly.

Office workers and high school students from 30 years ago remember the terrible lighting from that era – the greenish, corpselike complexions, the blurred vision, the flicker-induced migraines, the depression, even the supposed vitamin deficiencies from the limited spectrum of those old fluorescent tubes. Nothing says “factory farming” quite like that old whitish glare. And the buzzing noise they made… the list of physiological, psychological, and aesthetic impacts goes on and on.
Now, there are all kinds of “full-spectrum” lights out there, low-voltage halogens, and newer generations of fluorescents like the compact bulbs, that look a lot better and definitely save over incandescents. But qualitatively, which ones are really competitive for high-end residential design when appearance and aesthetics are paramount? We asked Ed Cansino, a lighting designer with over 25 years of experience, and here is what he said.
