I have been sent this video a lot.

Is that article really about science? He seems to be just lamenting the fact that there are no great methods for correcting eye sight.

I've started replacing my lights as well when they burn out. Unfortunately, the color difference was a bit of a surprise (I didn't think it'd be so noticeable).

The California Energy Commission (CEC) has
adopted new residential energy standards:
2005 Building Energy Efficiency Standards for
Residential and Nonresidential Buildings. These
updates to the Title 24 energy code include
comprehensive changes to residential lighting
for new and remodeled homes obtaining
permits. These standards will signifi cantly
reduce lighting energy consumption by
requiring the use of new energy-efficient
technologies.

50% of the kitchen’s permanently installed lighting
MUST be high efficacy, typically fluorescent; this can
include downlights, under-cabinets, over-cabinets,
pendants, wall sconces, etc.

Switching should be designed so the homeowner can
automatically turn off 50% of the lighting power, yet
retain illumination throughout the entire kitchen, with
no overly dark areas.

Fluorescent and incandescent light
fixtures MUST be controlled separately,
while different types of light fixtures
may also be controlled separately to
correspond with the use.

it takes about a half-second to turn on when I flip the switch

I'd replace more of my lights with CFL, but the lights I use 95% of the time are either dimmable or 3-way, both of which are not readily available.

I just don't get why LED lights aren't dirt cheap yet.

As for the intermediary screw size, its literally that, about a 1/2inch screw

On an unrelated note, I just replaced my 6 kitchen can lights with flourescent bulbs, for just under $30 total.

Interestingly to buy ones that used 1watt less would have cost me double.

There not that bad, take about 30ish secs to warm up to full light levels, but thats a minor price to pay for the savings. Plus they also produce more light than the previous bulbs!

Win win so far! Next up I have to find small bulbs for all my ceiling fan lights, they have an odd intermediary screw size which im guessing im probably going to have to find online.]

And this is just more evidence at how absurdly powerful the teachers union is in the US. If you really researched it, you'd be amazed at what kind of rules they enforce each year (such as one rule that states that children's books that contain pictures of elderly people, they cannot look elderly. Even though kids see senior citizens every day,) and what absurdity they get away with every year.

Teacher who threw feces at boy may keep job.
