🔦 Extech LT40 LED Light Meter: Accurate Measurement tool for LED Lighting Review

Very good tool - great form factor for surveying, portable and with good battery life. The features are easy to use and don't require a manual to figure them out. The self-calibration feature is a great addition to durability.

I use them as a health checker for restaurant checks. It's small and light enough that I don't mind carrying it in my tool bag every day. This is a luxury item as most inspectors don't care about the correct level of illumination when there are so many facilities with poor supply temperatures.

The only drawback is the lack of a backlight, which makes it difficult to read at night. Since the light meter was integrated into the device, no…

I received a nasty email from a grumpy neighbor who was complaining about our street Christmas lights. He hinted that we might be violating local lighting laws and rambled on about how our lights made it impossible for him to see the stars and night in Seattle in the dead of a gloomy winter. Yes. Before I told the old man to score, I wanted to make sure we didn't injure said flare, so I ordered this counter to be tested on myself. Ready to use straight away (batteries included) and I was happy…
