解析 含有汞,启动时间较长,易受频繁开关影响寿命,光线可能刺眼,能效低于LED 荧光灯泡的主要缺点包括:1) 含有有毒的汞,处理不当会造成环境污染;2) 启动时可能需要较长时间达到最大亮度;3) 频繁开关会缩短使用寿命;4) 部分人可能对荧光灯的闪烁或光谱敏感;5) 相比LED灯泡,能效较低且寿命较短。这些问题使其在...
Fluorescent light bulbs are a type of light bulb that use electricity to excite a mercury vapor, so that when the gas reaches...
Fluorescent light bulbs contain mercury -- a toxic substance -- but rather than recycle the bulbs, the company stored them in abandoned buildings around the state [source: EPA]. And in Illinois, a company that specialized in recycling toxic waste was found to have illegally stored plenty of ...
LED bulbs use less energy, last longer, and emit less heat than conventional lighting sources. Fluorescent tubes and CFLs are also energy-saving but less efficient than LEDs. LED Materials LEDs consist of the following main components: ● A light-emitting diode (LED) ...
What are 5 examples of hazardous waste? Common Examples of Hazardous Waste. Manypesticides, herbicides, paints, industrial solvents, fluorescent light bulbs and mercury-containing batteriesare classified as hazardous wastes.

Our phone, tablet and laptop screens are made up of tiny LED bulbs constantly pouring out artificial blue light. ARTIFICIAL LIGHTS LED and fluorescent lighting is common place in office and other workplaces. It's also a prime emitter of artificial HEV light. ...
Types of Fluorescent Lights: CFL vs. T5 Fluorescent lights come in two main types: CFL (Compact Fluorescent Lights) and T5 tubes. CFLs are the twisty bulbs you might see in your home, while T5s are longer tubes that give off more intense light. CFLs are great for small grows, but T5s...
Emission of light by a substance that has absorbed light. Fluorescence microscopy allows for detailed imaging of cells. 5 Fluorescent Used in lighting to produce bright, energy-efficient light. Fluorescent bulbs are common in office settings. 5 Fluorescence Can occur in a wide range of substances,...
