4-Light Type Selection: A Unique Advantage

The LX-1108's standout feature is its specialized 4-light type selection capability, which allows for accurate measurements across different lighting technologies:

Light Type	Description	Common Applications
Tungsten	Traditional incandescent lighting with warmer color temperature	Residential lighting, photography studios, theatrical lighting
Fluorescent	Gas-discharge lighting with different spectral characteristics	Office spaces, commercial buildings, schools, retail environments
Sodium	High/low pressure sodium vapor lighting with distinctive yellow spectrum	Street lighting, security lighting, industrial facilities, warehouses
Mercury	Mercury vapor lighting with blue-green spectrum	Industrial spaces, gymnasiums, parking lots, outdoor area lighting

This multi-type capability ensures accurate readings regardless of light source, as different lighting technologies produce light with varying spectral distributions that can affect measurement accuracy with standard light meters. The LX-1108 compensates for these variations, providing true readings for each specific light type.

Advanced Features Explained

Professional Sensor Technology Lutron LX-1108 4-Light Type Digital Light Meter

The LX-1108 employs an exclusive photodiode with specialized color correction filter that precisely matches the C.I.E. photopic curve—the international standard that corresponds to human eye light response. This ensures the meter measures light intensity as perceived by the human eye rather than just physical radiation, providing more relevant readings for practical applications. The sensor's cosine correction factor standardization further enhances accuracy by accounting for the angle at which light strikes the sensor surface. This means measurements remain consistent even when light comes from different directions, not just perpendicular to the sensor.

Five-Range Measurement System Lutron LX-1108 4-Light Type Digital Light Meter

With its five selectable measurement ranges, the LX-1108 offers exceptional flexibility across the entire spectrum of illumination levels:

• 40.00 Lux Range - Ultra-high resolution (0.01 Lux) for measuring very low light levels in emergency lighting, night environments, or dark rooms
• 400.0 Lux Range - Suitable for normal indoor lighting assessment in offices, schools, and homes
• 4,000 Lux Range - Ideal for brighter indoor environments, workplace safety verification, and commercial spaces
• 40,000 Lux Range - Perfect for measuring bright indoor lighting, covered outdoor areas, and partially shaded daylight
• 400,000 Lux Range - Capable of measuring full daylight, direct sunlight, and extremely bright artificial lighting

This extensive range capability eliminates the need for multiple meters or accessories, making the LX-1108 suitable for virtually any lighting measurement application across different lighting technologies.

Advanced Data Functions Lutron LX-1108 4-Light Type Digital Light Meter

The LX-1108 offers several sophisticated data handling features that enhance its utility for professional applications:
