## Overview

The Extech LT45 is a compact, LED-compatible light meter designed for professionals needing accurate illumination readings in diverse environments. Featuring an integrated sensor, it eliminates cord management issues and supports lux and foot-candle measurements. Its rugged design includes a protective cover, hard case, and a 9V battery, making it ideal for OSHA compliance and workplace safety verification across offices, industrial sites, and educational facilities.

## Description

The LT45 LED light meter is useful for measuring and optimizing environmental light levels in a wide range of environments, including office buildings, manufacturing plants and warehouses, university campuses, schools, hospitals, and many other locations. OSHA regulates workplace lighting because illumination must be adequate for assigned tasks, and light meters are used to verify regulatory compliance, as well as state and local public safety codes and ordinances. Use of LED lighting is on the rise because it is more efficient to operate, it emits stable, high quality illumination, and the technology is dropping in price. The LT45 comes with a 9-volt battery, protective sensor cover, hard case, and user manual.

Review: Compact, affordable. I like it! - Really like this compact size versus my previous Extech LT300. The old meter died after 5 years and needed a replacement. This is the "LED compatible" version so I can get accurate readings no matter what type of lighting I'm measuring. The sensor is built into the unit instead of attached to a cord. I like that better because no cord to get tangled and I don't need 2 hands to do my readings (since I normally have something else in the other hand). Easy to use, easy to read - hope it lasts at least 5 years!
Review: Quality meter without the wires - For the price, works great. Purchased this for use in acquiring night light meter readings on roadways. It allows for lux or foot candle measurements. The instruction manual covers the quirky min/max average function. Otherwise, it did a great job on the jobsite. The included bag provides for good storage and the device is sturdy and works good in a commercial environment. The only issue is there is no back light, which made night readings a little difficult. The fact that the light meter was integrated into the device meant there was no additional wires to manage.

### ⭐⭐⭐⭐⭐ I would buy it again.
*by D***K on December 22, 2014*

The Extech LT40 LED Light Meter is easy to use and appears to provide reasonable measurements. I say reasonable as i have no good method to determine the true accuracy of the meter, and the readings i get appear within a window of what i would expect for common light sources. I typically use it for readings of 10 foot-candles and below, usually in the 0.3 to 3.0 range, and with LED lighting, induction lighting, and metal halide lights. I performed a couple of measurements in an office environment and compared the readings to a lighting print of the area, and my readings were in the general area of what one would expect for the office area, and compared favorably with architectural lighting prints. The only drawback so far for me is the display is not backlit, so using it in the darker environment I am typically in can present a challenge at times, however, worst case I use the Hold feature and then read the display. Also, since the detector is fixed to the meter and not even rotatable, at times taking readings requires using the Hold feature if the meter needs to be facing away from me. For the money and the ease of use, I would buy this again.
