  • low energy = low power, high-efficiency, efficient, "green" = Typically LED or CFL, such "low-energy" lighting is many times more efficient (in terms of light output power for given input electrical power) than "standard" incandescent tungsten-filament bulbs, which of necessity must get very hot and generate a lot of heat.
  • low energy led = LEDs, Light Emitting Diode, Solid-State Lighting, SSL, LED light bulb, LED-leuchtmittel, LED-lampen, ampoule à LED, bombilla LED = See also LEDs. A physically tough/robust solid-state semiconductor light-generation mechanism with efficiencies in lumens per Watt (lm/W) and useful lifetime significantly exceeding that of CFL (compact fluorescent), available retail for domestic use in a number of roles/settings.

  • closeup = close-up/macro; tightly framed and imaged at a relatively large scale

  • low energy = low power, high-efficiency, efficient, "green"
  • low energy led = LEDs, Light Emitting Diode, Solid-State Lighting, SSL, LED light bulb, LED-leuchtmittel, LED-lampen, ampoule à LED, bombilla LED

These claim an A+ energy rating, 4.5W, 351lm and 630 'effective' lumen, along with a 50000h life. To my eye the cool is far brighter than the warm, so I'm not sure how they can have the same lumen output!
