This long-time bestseller has been redesigned and now makes its reappearance. The light sources are fluorescent light tubes which produce no heat, and because it has an inverter you do not need to worry about the power frequency (50Hz, 60Hz) when using it. It is safely designed such that in the unlikely case that the fluorescent tube breaks, the shards will be contained inside the outer tube and none will scatter outside. Choose the right brightness of lamp to fit the use and place of installation.
