The type of light bulbs that waste the most energy are incandescent bulbs. They are least efficient because around 90% of the energy is lost on heat. They are also the shortest-lived light bulbs.
The most efficient lights are LED lights, followed by CFLs, followed by the new Halogen incandescent bulbs.

They use less power for an equivalent amount of illumination compared to incandescent lights which waste a lot of energy in heat.

Thermal energy.
Tech lighting is just a brand, not a type of light. They offer a lot of unique alternatives with low energy emissions. From pendant lights and wall lighting to track lighting outdoors, and monorail lighting systems.
it's because people sometimes run a lot and waste their body energy
Yes; the average nuclear power plant yields about 3 tons of radioactive waste each year.
A lot of gunpowder or whatever it has, I think the fuse lights the gunpowder and it explodes!
Nuclear. Hence Nuclear bombs. Which shows they contain a LOT of energy. A LOT.
Nuclear Energy is already clean. The problem is the 'radio-active' waste from the reactor. A lot of research is going on to dispose of radio-active waste safely. One possibility is 'vitrifiction' and then burying it in deep mines.
Gamma radiation is a type of nuclear radiation made of high energy waves.

Lights use a lot of energy and when you sleep or walk out of a room. You should turn off your lights. This extra energy could be use to power something more beneficial.
