The LED lamp 30W E27 has 100 lumens / Watt is very excellent light efficiency, which is überbietbar in any competing product in Feb. 2014. 3000 lumens perfectly illuminate a room with about 12 m² very bright so from that, which is very pleasant even see already worse for older persons. The packaging was so little padded with delivery in Feb 2014 too thin (only paper bag), and thus so flawed that the lamps arrived disintegrate into individual parts. The bag was torn. However, the individual parts could be put together again, so that the function was OK. Except for the packaging a strong buy recommendation. The lamp lights up perfectly bright as a 220W light bulb.
