Hi Looks like mine messages had some writing errors, but i think you got still what i wrote. It took time because i had to watch the title what was in there to tell what was in it. Gonebananas hi You welcome. I have found the book you mentioned, but it cost more. Scottfsmith hi How much you learn information about peaches from this book depends how much you know about peaches. If you know a lot of peaches you probably don't learn so much new things by reading of peach book.

That is required in the latest rev of the title 24 requirements document.

I was told that drop-in replacements using an Edison base would not qualify in our jurisdiction as a high efficiency luminary. As it is with all situations, a lot depends on your local building inspectors. The regulations in kitchen are even more complicated than in other areas of the home. If you have already determined you will need to swap our your existing lights, then you may need to swap out the can to an air tight model with an acceptable (GU24 or proprietary) connector. There are provisions for existing luminaries, I think, as well as you could spend your "low efficiency" wattage on some noncompliant light. Your GC or electrician will be able to tell you.

wws, I don't think that the "first light" rule is sufficient any more. Since the 2008 version of Title 24 went in to effect (in 2010), the choices are: 1. High efficacy -- FL, CFL or APPROVED LED. To be approved, it has to be on the official California Efficient Appliance list, and not have a screw-in (Edison) socket in the fixture. Adapters from Edison to others (such as Edison to GU24) are NOT allowed/recognized. or 2. Whatever lighting you like, as long as it is on a "vacancy" switch. i.e., it has manual turn-on and turn-off, and will also turn itself off after no motion detected for XX minutes. Note that "occupancy sensors", which turn on when you enter, are NOT allowed. There are motion detector switches which can be configured (e.g. by a small switch behind the wall plate) to be either "occupancy" or "vacancy" -- these are also NOT allowed. I'm in the middle of a gut-out remodel of several rooms, plus 4 baths and a kitchen. In the master bath, I have incandescent/halogen over the vanity (on a vacancy switch), plus CFL recessed on a separate switch. My contractor thought the 1st switch rule was still in effect, so he put incandescent in the shower (separate switch) -- I'll have to either put that on a vacancy switch or replace the Edison base with a GU24 base and put an approved LED suitable for showers. Please note that recessed lighting with a GU24 socket is NOT approved with CFL installed, only with an approved LED. Not required, but in the master bath I also put my Panasonic combo ceiling fan and heater on timers -- 1 hr max for the fan and 30 minutes max for the heater. For my master half bath, just a 30 minute fan timer (and vacancy switch for the incandescent vanity light). Here is a link that might be useful: CA approved high efficacy list - search
