Delivery and packaging well. Have two of the LED bulbs installed in ceiling lights and the existing energy-saving lamps replaced 20 and 23 watts. It took me just disturbed that it took the longer, until they have reached their luminosity. So bright I had then never in this room. Significantly lighter, as with the energy-saving lamps. Since it can be assumed that 20-23 watts of energy-saving lamps the seller information are replace 100 watt light bulb realistic. Am, however, happy that I've been waiting for the warm white version of the pear. The light from the cool white version would have been likely to me sterile. Have recently a 14 watt LED bulb purchased with allegedly 120 Watt light output, which is also not bright. Personally, I am very satisfied, if still plays along the life, then everything is OK. The only on that you should pay attention before buying is that the bulb fits in the provided light because the LED bulbs are larger but the format as a standard bulb.
