urgh.

did the acceptance tech update tonight....

they changed the portal to reflect the new changes in
the calif. lighting controls, and it triggered a mass
access of the module for the renewal of the AT certificate.

so, it seems everyone was trying to flush a grapefruit
down the toilet at the same time tonight.

half the audio wouldn't play, and the pages on the powerpoint
wouldn't run.... got it done, but it took 4 hours instead of 1 hour.

i'll post a thread on changes over the 2013 T24 rules when i get a
moment. there are some significant changes.

institutional tuning, and PAF credits for daylight harvesting + OFF
are the bulk of it.

that, and a number of exterior lighting rules.

and, those occupancy sensors that turn the lights on in offices?
they now have to turn them on at 50%, then they can be manually
adjusted up or down as wanted.

when the lights come on after a vacancy, they go to 50% again.

means everything needs programming now. defaults in most cases
don't do this.

oh, the thrill.

2016 T24 also describes the JA8 light bulb standard, which I haven't seen anywhere, for screw-shell luminary replacement lamps.

How is this enforced if required equipment is "Not commercially available", or if no-such-animal exists with default at 50%?

Amazing to read for those of us in the lands of relatively few regulations.
I pity the inspector that drives 5 miles down a back mountain road (just past the sign "have shotgun & backhoe") to tell "bubba" he can't have that type lamp in his home.

It's amazing to me. It seems the days of the simple light switch have long since passed in California.

I wire dairies 90% of the time, so I still use light switches with a few LED fixtures thrown in once in a while and an occasional occ. sensor, but that's it. California is definitely a different world.

it's not an issue in the home.
you can run gas lighting for all i care....:lol:

now, tell bubba that he has to only use organically
grown corn in that still run he does each spring....
i wanna watch.

and when he twists and doubles it, there needs to be
a third party inspector to proof it. and no boosting it
with 200 lbs of sugar in the mash. cheating. :happysad:

we have standards here.

I think it's a welcome change. This should avoid problems.

To qualify as high efficacy... have GU-24 or 4-pin GSFL socket

or... have JA8 approved lamps fitted in screw base at the time of inspection. JA8 for screw base lamps is conditional to having fully enclosed/high temp rating.

Screw base exemption do not apply to down lights.

Lamps that meet JA8 specs are rare, because they're not exactly technically feasible. People do it anyways but you're not supposed to install most screw base LED/CFLs in totally enclosed fixtures. Heat builds up and ballast burns out too soon. People get dissatisfied and snap-back to low efficacy becomes likely.

pin-type CFLs take an external ballast which can be kept away from lamp heat and CFLs can be made with amalgam for enclosed, high temperature use. Some LED lamps force dimming to avoid blowing up the LED elements or its ballast. It works just like a computer CPU protection. Protected CPU won't get damaged form blocked air flow, but gets stuck in a limp mode. Using it in an enclosed fixture is like running your computer with the fan turned off. It will work at maximum performance for a few minutes, then it throttles back.

Fully enclosed includes fixtures with the lamp covered all around even if they're not gas tight like jelly jars.

Rated for enclosed means the lamp needs to perform at the advertised spec inside enclosed fixture, retain warranty and advertised life. Not going to happen for 60 or 100W replacement hanging by just the base. At least for a while. LED fixtures are like something else because LEDs are thermally bonded to the fixture frame.

it's not an issue in the home.

I think the difference for the compliant version is the absence of setting that lets the user revert to legacy mode. T24 residential certified vacancy sensor do not allow setting to auto-on while a non-certified type gives you the choice of auto on vs manual on. You shouldn't have any problem finding materials once you actually need to use the 50% dimmed start sensors.
