I highly recommend these bulbs because they wonderfully replace the former energy-saving lamps and help further save more than half of electricity. One should only look closely at the application and then determine the number of lumens, which is necessary. Compared to halogen bulbs, which everyone knows well, the rule of thumb: multiply halogen-wattage about 10, then you have an approximate Lumen value should the LED lamp half as a substitute. For example, a 25-watt halogen lamp is replaced with a 200 lumen LED etc.
