Light Meter

[Octopus]

Ok, don't know much about these, are they useful?

I know test-meter sell one for about £40.00

Any useful input??

Thanks

Never had cause to use one but it depends on the sort of work you are doing, would it really help you in day to day life?

Last time I used one was 37 years back. Part of an EITB phase test.

Luxmeters are quite useful when doing EMlight measurements.

You need one sensitive to measure down to 0.1Lux accurately. That would probably mean you'd need a resolution of 0.01Lux.

You'll be looking at spending £100+ for a reasonable instrument.

I do a lot of lighting for various types of requirements. I have a very good eye but when using the meter i can find dark spots easier. With Em you can at least confirm the light level, although its a pain in summer waiting for the sun to drop

I agree, don't do EMlight testing in June. Caught caught on that one once and was on site measuring light levels into the early hours.

I tend to work in supermarkets a lot doing energy saving works and use a Testo 540 meter to adjust the light levels down to the specified levels and that cost about £100 with the calibration certificate, but funnily enough never had to use it to test em lights yet

Since you'll only use it occasionally, just hire it when required. That way it's always callibrated.

Buy your own & with only occasional use you'll be having to have it callibrated every year or if you use it even less frequently then you're looking at callibration costs every time you use it.

bought one years ago for a job and after that have never needed it just sat gathering dust.

Hihihi...same like me @phild

Yes got loads of stuff that I thought would come in handy and most of it only came in handy for attracting dust.lol
