How do energy-efficient bulbs compare to incandescents for light output? And how do they stand up to being continually switched on and off? Consumer NZ tested 19 models to find the ones that shine the brightest and last the longest.
LEDs have been round since the 1960s. But it’s taken years of continuous development to transform them into devices bright enough for general lighting – and that development continues, so LEDs should get better and cheaper.
Many homes have downlights, and changing them to low-energy bulbs could make a big difference. But the ventilation gaps downlights need act like little chimneys, stealing warmth and racking up heating bills. Consumer tested downlight fittings and bulbs to find the most efficient.ns.
Uplights, downlights, pendants, chandeliers, soft lighting, ‘task’ lighting - there are now energy efficient bulbs for every fitting and every situation. This Consumer NZ report will help you choose which sort of light is right, where.
