I think that is a very good strategy as there are no guarantees that a more expensive luxmeter is as much better as it is more expensive. Unless you get to the hundreds of dollars category, where all specifications come with accuracy claims so you really know what you get.
When the meter arrives you could check for:
-calibration: does it give the approximate correct reading if a flashlight with ANSI-rated lux-specifications are measured (within 10% is already great, 20% still acceptable)
-repeatability: with same light source measured in the same set-up, does it give consistent results (in time, with varying battery levels, varying temperature etc.). I think this is the most important characteristic of any luxmeter, and I found that even very cheap luxmeters can have a good repeatability.
Hey, had that exact meter on order from a AliExpress seller, it was a deal 50% off
But it did not arrive and purchase protection was not extended so got a refund, still no meter though. I might just get this on instead (or at Gearbest depends on where the most points/discount is now.
Lol I have am old analog lux meter, that barely measures sunlight
Well the meter has arrived, 8 days from ordering to turning up at my house in the UK, well done Banggood that is the fastest anything from China has ever arrived
Now can anybody suggest a light meter app for an Android phone as I would like to reference it against something.
I will use a light with a known ANSI rating first to judge how accurate both the light meter & app are.
Oh & can somebody point me to good thread (or explain) on how best to use the meter & interpret the results please.
Ah well I have tried half a dozen times & can”t post a pic, again
I don”t know what it is with this forum & pictures but of the forums I am on it is the only one I always struggle with.
Done that the same as before & dosen”t work.
Have tried transferring the pics from dropbox to tinypic & tinypic says invalid code ?
The other forums I use putting up pics is simple this one is always a struggle.
