The new lamp is much better; instant-on and seemingly brighter anyway. Yes, this was a quick test and the fitting still needs a good clean!

- 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.
