In the '80s and '90s, it seemed *very* trendy to use PARs in plain downlighter cans virtually everywhere. New home construction, old home renovation, new offices, old offices, etc. I remember seeing a typical kitchen rework going to 11x downlighter can, each with a 90w PAR38. Floor was nice and hot, but counters were cold, so add about 10x F15T8s into the mix, which gets the counters but not the cooktop, so add 2x 75w A-line into the range hood...sheesh.
8x eyeball cans with HIR 54w PAR38 wide floods: MUCH BETTER overall illumination (floor hot enough to see adequately; work surfaces and cabinets well and evenly illuminated), undercounter F15s no longer needed,
1/3 the power.
The quick 'n' dirty means where installing eyeball cans isn't practicable or affordable? Track lighting.
Please take a look at these photographs of my halogen light bulbs. The only thing written on them are 12V 50W and some brand name. Please can someone help me identify the proper code name for them. Thanks!
Now that we have identified that my bulbs are MR-16:

you advise me on the lowest-energy / energy-saving-light-bulb-like bulbs that I can purchase for the socket type that I have. Or are the bulbs am using the cheapest/lowest-energy I can use?
I prefer using the energy-saving light bulbs (11W, etc.) Bayonet B22 or ES base fitting. Is it possible getting a convertor from the current sockets I have, or do I have to get an electrician to replace the sockets?
You could theoretically install 12V 20W lamps in the same style, but depending on the type of transformer and the loading, the voltage may rise slightly. If it's 11.5V to start with then that may not be much of an issue. Have you any idea if it's a separate transformer per light or if there's a common transformer?
Another option would be to install the LED version of the lamp, but their output is very low and the white tends to be rather harsh.
There are halogen lamps with a heat reflecting coating around the bulb. The same light output is achieved with lower energy consumption. In your case you can replace a 50 W lamp with a "new generation" 35 W lamp. Such lamps are manufactured by Osram and Philips for example:

that MR16 halogen lamps are available in different beam angles (spot, flood, wide flood, very wide flood).
More savings could be achieved with compact fluorescent lamps, but they have other dimensions.
