4. EL Limitations Low light input Susceptible to moisture and ultraviolet Color shift Cost effective manufacture Short life
5. Recent Developments Higher output, long life phosphors Microencapsulation to prevent degradation by moisture Ultraviolet absorbers Controlling of colour shifts dye conversion Efficient, lightweight power source of 400Hz and above
6. EL Advantages Over Incandescence Has no infrared radiation emission Has no ultraviolet emission Emits in narrow bandwidths Is compatible with Night Vision Goggles (NVG) Provides excellent scene contrast Does not fail catastrophically Low Power Consumption No Light Pollution Environmentally Friendly
7. EL Area Light Helps eliminate glare Improves contrast and visibility Is Flexible/Durable Reliable, low maintenance Low power consumption and cool
