- These bulbs keep bright for 4 hours when there is a power outage - The light bulb has a built-in sensor to determine the state of the switch and will automatically stay on if there is load shedding or a power outage and the light switch is in the ‘ON’ position - It needs a 6-hour charging time to restore it to its full brightness - When using the light bulb for the first few times it may flash or flicker. It is not faulty. The battery is building up ‘storage memory - Please use it and recharge the battery at least 3 or 4 times for the first 2 – 3 days - The bulb works best when used alone in one fitting, with one switch to control it. Having multiple bulbs/fittings on one switch will reduce the efficacy of the bulb - automatically recharges when Eskom power returns. Saves 80% of energy compared to a traditional incandescent bulb Very dim light, can be used as a childrens night light as well
