Rethinking the incandescent lightbulb

WebThe brightness, or lumen levels, of the lights in your home may vary widely, so here's a rule of thumb: To replace a 100 watt (W) incandescent bulb, look for a bulb that gives you about 1600 lumens. If you want something dimmer, go for fewer lumens; if you prefer brighter light, look for more lumens. WebFor the four-Ln-component (La,Er,Tb,Eu)-terephthalate thin films, intense warm-white-light emission was successfully realized. For the multi-layer La70-Er10-Tb15-Eu5-ML sample, the emission colour characteristics were comparable (and even exceeding) to those measured for commercial incandescent bulbs, fluorescent tubes and LED lamps. citalopram dose in the elderly
