I bought some of these 57 watt halogen bulbs at a local hardware store. I realized afterward that they produce only 790 lumens of light. That seems a steep price to pay for dropping power consumption 3 watts, because the 60 watt version produces 900 lumens. Let's see: 790 lumens / 57 watt = 13.86 lumens per watt, and 900 lumens / 60 watts = 15.00 lumens per watt. Watt for watt this 57 watt bulb is less efficient than the 60 watt 900 lumen version, and may encourage people to substitute a higher wattage bulb which would defeat the purpose. This bulb might be ok if you don't really need a 60 watt 900 lumen bulb, but a 40 watt bulb is not bright enough. Turning off uneeded lamps is a good way to conserve energy rather than making bulbs dimmer.

We use these in our external garage lights and they work great. Nice and bright and their halogen-filled, clear glass chambers make them brighter, or seem brighter, than a regular 60 watt bulb. These are so bright that it is hard to look directly at them for any length of time.
