Been using CF and LED bulbs for ~two (2) years.  Garage light is a CF equivalent to a 200W incandescent, but uses between 1/3-1/2 the power.  Several desk lamps with multiple small LEDs, usually ~thirty-six (36) have been working just fine to illuminate various keyboards and desktops.  Not super bright, but adequate.  Have a couple of torchiere floor lamps with variable controls for light levels.  Cannot get super dim, but dim enough, I suppose.  Significant power bill reductions, although I cannot quote values, as this has been happening over time.  Now looking for 100W ceiling fan replacement lights with variable capability.  Also looking for 40W equivalent bulbs for a spider light with five (5) elements and variable lighting, but I suspect that may take a while.  Biggest gripe I have is converting watts to lumens  :-\ ;D.

Considering that I'm pretty much planning on dying here, the costs are not significant, since I'll prolly never have to replace a bulb - except for experimental purposes, of course.  Only other LED I need to find is a weather-proof variant for the front porch.  Not difficult to find, but too many choices, so the choices can get confusing pretty quickly.

I wish now that I had kept better track of power and billing as the project grew, but that didn't seem significant at the time  :-\, as that was not a major purpose - I just got tired of replacing incandescents  :P.

I suspect these things depend on your posture and, if relevant, your reason for having back pain in the first place. I'd imagine that standing could help correct, or exacerbate a back problem, depending on what it is.

Imagine no more  :-\.  As an old cripple, I have a fused hip.  It's fused fifteen (15) degrees forward and ten (10) degrees to the side.  As a result, I neither sit nor stand comfortably.  Drives me crazy when I read about proper posture anent discussions about sitting or standing while at a desk  :'(.  I've been able to use a slant board in the past for extended coding/reading sessions, but that's not a currently viable option  :(.  And sitting or standing for more than about twenty (20) minutes at a time aggravates lower spine (degenerative disk disease, lower five (5) vertebrae).

Not bitching about it, and this thread has been quite entertaining - almost comical at moments - but I stand/sit as a tribute to the phrase that not all things fit all people  :P :P.  (You should see my reaction(s) to most exercise commercials  ;D.)
