Re:LEDs I think.
If it's hard wired, I can just cut the cables and put in whatever I want and solder it back together. Pin bases support a plethora of bulb types. For instance GU24 base typical for CFLs also is supported on LEDs. https://www.bulbs.com/results....

Re:I love LED lights
.CRI, Color Temp, Initial Illumination, Time to Full Output. None of that data is available, and it makes purchasing a random event.
Random?
Apart from the slow to startup thing which is not really a problem.....
CRI and Color Temp are hardly random..
for example, this website http://www.bulbs.com/Spirals_&_Bent_Tubes/results.aspx tells me the CRI and color temp for nearly every product! Truly random indeed!

Re:"using a lot more fossil fuels than they save"?
The energy payback is within the first hour of use.
I figure you can fit in ~300000 CFL bulbs in a container.

Wikipedia says it takes 85MW to bring a certain class of container ship up to speed.
http://en.wikipedia.org/wiki/Container_ship
One limit on ship size is the "Suezmax" standard, or the largest theoretical ship capable of passing through the Suez Canal, which measures 14,000 TEU. Such a vessel would displace 137,000 metric tons deadweight (DWT), be 400 meters long, more than 50 meters wide, have a draft of nearly 15 metres, and use more than 85 MW (113,987hp) to achieve 25.5 knots,
Which works out to 1/50th of a watt per bulb. Thats such a small number, trying to calculate the cruising energy seems fruitless...

Re:Paycheck to paycheck
PLCs? What are those in this context? I don't think it's a Programmable Logic Controller.
T8/T12 Bulbs really are cheap, especially for standard sizes.
For example 48" T8's are $1.99 each, but have a CRI(Color Rendering Index) of 78. Meanwhile one with a CRI of 95 costs $6.79.
Given that they can be expected to last 20k hours, I'm not going to complain about spending an extra $5 for better bulbs(3X!)
Though I didn't get the most expensive. -
They work, just specific ones:

Candelabra base (E-12), dimmables & UVWe live in an old house -- part of it is still on knob & tube wiring with four screw-in fuses (scheduled for renovation in a few years). Many of the fixtures take candlabra base bulbs. There are candelabra base CFLs but they are hard to find & huge in the 9-13 watt range (40-60 equivalent watts). I eventually bought a case of 12 9-watters online for something like $80, and put them in our most frequently used fixtures. But the price of candlabra base CFLs is way too high: see http://www.bulbs.com/products/product.asp?page=pr
o ducts&class=817 or http://www.bulbman.com/index.php?main_page=index&c Path=4595_4616.Same thing with dimmables. I bought one to see how it performs and ran it thru my "kill-a-watt" http://www.fadfusion.com/selection.php?product_it
e m_number=30183200136&gclid=CMbYwsKph4cCFRskUAod1DU eZQ meter. At max, the bulb draws 25 watts; at min 10 watts. Perceptually it's just not that dim at its minimum setting. Now try finding a dimmable CFL in a candelabra base -- can't be done! I'd like to put more swirls in the house, but many of our most frequently used lights are dimmable and/or candelabra.By the way: a fun bulb for halloween is this: http://www.bulbman.com/index.php?main_page=produc
t _bulb_info&cPath=4595_8457&products_id=13846. You can be in ultraviolet heaven for much lower prices thanx to these kinds of black light (ultraviolet) bulbs. Makes me wonder: is the black light niche market bigger than the dimmable candelabra niche?
