Review: Valuable products - Good product
Review: Basic lighting on powercuts - The Bulb works reasonably well during power outages, providing a decent source of light when needed. However, its luminosity is somewhat limited for medium-sized rooms. IThis bulb is not ideal for reading or detailed tasks, as the light tends to feel a bit misty, which can cause eye strain or discomfort over time. For better illumination and more comfortable reading conditions, opting for a higher wattage emergency light, such as a 12W model, might be a better choice. Additionally, the bulb requires prior charging to function effectively during power cuts, and while it offers a decent backup, it doesn't quite live up to the claimed 3-hour runtime. Overall, it’s a satisfying product that provides basic emergency lighting needs.
