Best Light Meters for Lighting Design in 2020

Understanding how light will affect an indoor or outdoor space can be daunting. Besides figuring out how many lumens is needed and how well the distribution is, light has other properties such as light levels, energy savings targets and government code requirements. On top of that, you can add glare, reflectivity of light, comfort levels and whether or not the light can be controlled. Often daylight is either present or not, and that can create a complex puzzle for light engineers. We all want to deliver a space that is energy efficient and well lit.

A good place to start is by using a light meter. A light meter will read the amount of light in your space. It will allow you to decide whether or not the light you have is appropriate.

#20 LEDLightingSupply - Light Meter ennoLogic eL200K – Digital Illuminance Lux Meter Photometer 0 to 200,000 Lux – Auto-
  • THE ENNOLOGIC LIGHT METER eL200K measures illuminance, the amount of light incident on a surface per unit area. Illuminance is measured in lux or foot candle, and the eL200K displays both. It is a great tool for measuring light levels in offices, labs, warehouses, classrooms, and homes. Useful for checking desk and work surface lighting, and to compare light levels in different environments. Indispensable when establishing safe or minimum levels of illumination in a work or living environment.
  • WORKING ON THE LIGHTING IN YOUR HOME? It can be very difficult to objectively assess light levels with the naked eye - use this meter to get an accurate reading of the actual light levels every time. Compare different lamp types and wattages. Check the light level when installing accent lighting. Or maybe you're replacing incandescent light bulbs with LED light bulbs? Use the ennoLogic lux meter to compare brightness before and after.
  • DO MY PLANTS GET ENOUGH LIGHT? The quickest way to find out is with a portable luxmeter like this one. Whether it's for your beloved orchids, indoor herb garden, hydroponics setup, plant nursery or greenhouse, the eL200K makes checking light levels easy. Maybe you're using LEC grow lights and are wondering how much light actually gets to the plants? This tool will give you the answer.
  • MANY OTHER USES: Find out how many lux of light the light box you use for bright light therapy puts out. Or maybe you need it for a science fair project. IMPORTANT NOTE: The ennoLogic lightmeter is NOT for photography. This device does NOT allow you determine the proper exposure for a photo. Its purpose is to show you light INTENSITY in lux or foot candles at any given spot.
  • RELIABLE AND ROBUST LIGHT METER: Measurement range 0-200,000 lux. Lux and Foot-Candle units. MAX, MIN, and AVERAGE reading display and ANALOG BAR GRAPH DISPLAY. HOLD function. Analog outputs (DC and AC). Large 1.5"" LCD display with BACKLIGHT, easy to read even from a distance. Tripod mount (tripod not included). External power option. Auto power off with override option. Comes with carrying case, 4x AA batteries, analog output interface cable and user manual. 10 YEAR WARRANTY.
