google says SMS is text messaging... unclear about what you are saying/
Quite literally you want to play football after dark, so you text 'light' to the number on the fence and the floodlights come on for an hour (and you get charged 50p on your phone bill)>

Since I don't have a smart phone or ever text messaged anything to anybody I would be ignorant to that modern contrivance (among others).

Text messaging was more prevalent outside USA as you guys had 2 way pagers (which were much the same). It was originally a bolt on to the original GSM specs to allow activation of your new phone but then took on a life of its own, at least until smartphones and messaging apps appeared.

I miss MSN, it was simple and worked...

So here we are eight years later...

Today I bought a 4-pack of 40W (equivalent) 460 lumen Ecosmart LEDs at Home Depot for $5.12 US.
That's $1.28 each which is a 27-fold reduction in the 2011 price of about $35.

Gone is the aluminum heatsink and it's huge embedded energy.
It looks like LED's pricing are now about the same as incandescent lamps.

I only have incandescent lighting in three places: The electric oven, the Lava Light and in the garage freezer.
I don't have a single florescent light anywhere.

Of all the first generation lights two models stand out as excellent: The Sylvania PARs and the GE 62180 40W with fins.
I've replaced many of the first generation A19 Edison-based bulbs, not because they failed, but the replacements got so much better in terms of dimability, color temp and efficiency (low heat).

Disregard the clutter and old shopping bags on the floor. I just installed a nice 24" LED light bar in the ceiling over my sink. Less than $10 at wallyworld. This will surely motivate me to clean my sink better/more often.

There was a short curtain above the sink, now in my dirty laundry hamper waiting for this weekend's wash session. Since it hadn't been disturbed in the 30+ years since I moved in, I will find out what color it actually is, after cleaned. Replacing that curtain will cut down on the glare in the picture.

I fired up my vacuum and removed a couple decades of spider webs now glaringly obvious. :lol:

I try to keep my kitchen sink task light off for that very reason.

Well....now two brand new SYLVANIA "60 Watt" bulbs have failed within a few months. Flickering like a disco light.

Grrrrrrrrr BULLSHIT! I want the Olde GE incandescents back. They seemed to last for 1000 hours versus dozens of hours for these Mandated trash bulbs which cost much more.

LED lamps.
You can roll your own.
LED module + constant current power supply + heatsink.
Modules from 10W to 100W and compatible CCS are available at very low prices direct from China.
Heatsink, I am pretty sure you have or can get from junk.
Have fun designing a decent assembly with good protection for the modules.

I'm the poster boy for cheap but when I can buy a 24" LED fixture with line cord and switch for <$10 I have no motivation to roll my own. Did I mention I'm cheap?

@ Brian- I have almost forgotten the near constant parade of incandescent bulb failures. The early LED lamps had a few issues, but modern stuff is cheap and robust. I am still using 3x60W incandescent bulbs to heat my green house (with thermostat). I already had to replace one burned out bulb last fall. Turned off now but I will turn it on again soon when I plant seeds for next years plants.

I recently installed two inexpensive LED fixtures in my laundry room... Now I can see how dirty my old dryer is..

I have had difficulty getting enough light to read in my comfortable chair. The very old floor lamp with a 150W 3 way bulb was marginal, but modern 100W equivalent LED lights were not getting it done. I just broke down and ordered a new floor lamp with an extra fixture to direct light at the chair... I popped in two LED bulbs and not only was it too bright (my house is not very clean and tidy) and the two LED lamps were very noticeably different colors... no bueno. I have since put a smaller, same color lamp in the top fixture and the new lamp is a real benefit.

The translucent plastic shades, put out a lot more light. This lamp was so cheap I am not even going to complain about top fixture 3-way switch stem being broken and completely missing. I don't need the 3 way function. At least it is broken turned on.

Now I can actually read in my comfortable chair (if I find some more time.)
