I already have other LED bulbs in the apartment on the insert (Segula, built in 2008) and the difference in terms of brightness and color (warm white) is truly remarkable! These bulbs I ordered to replace the energy-saving lamps (torpedoes Philips) in the kitchen.
The advantages: the light is brighter, the consumption is lower and the bulb has been after switching the full brightness. Disadvantages: in the price (currently ~ 14) no.
