Benefits of LED

LED (light emitting diode) solid-state technology is currently one of the brightest and most energy-efficient (lumens per watt), longest-life, and lowest-maintenance lighting options available. A summary of LED lighting benefits are listed below:

Long life - lifetimes that can last decades (from 50,000 (17 yrs at 8 hrs/night) to 100,000 hours), many times that of other types of lighting, making them a great solution for hard-to-reach or costly to replace/maintain locations like street or parking/area lights.
Energy efficiency - In general, LED lights are significantly more energy efficient than other types of lighting (as much as 90% more).
Brightness - (warm 2500-4000 kelvin) best for inside; (white or colder light 5000-7000 kelvin) best for outside applications—whiter light allows you to see better at night and typically has a longer life.
Durability and robustness - no moving parts, no glass, no filaments; resistant to shock, vibration, and temperature extremes. Solid-state LED bulbs are arranged in clusters (or multi-arrays) and can continue to provide light even if one or more emitters fail, unlike a single-filament bulb.
Non-toxic - eliminates hazardous waste issues that are typically associated with other types of lighting that often contain mercury.
Instant-on & versatile - no warm-up time required (some take up to 10 minutes), no flickering, can be dimmed or pulsed, and available.
Cool - less heat radiation than HID (high-intensity-discharge) or incandescent lighting.
Lower overall product life-cycle cost - LED lights are more expensive to purchase initially; however, they can last significantly longer (decades vs. a few months or years) which translates to lower maintenance costs (fewer bulb replacements and labor/equipment associated with frequent bulb changes) and significantly reduced energy requirements.
Solar friendly - LEDs are dramatically more efficient than conventional lights, making them ideal for solar applications. Enable significantly more light output (lumens/watt) and less battery storage needs due to the increased energy efficiency.>
