ELECSA Certification Scheme Lux tester and elecsa thanks

[Rockomuir]

Hello Gents, just wanted to say thanks to all those who helped with queries and advice about my elecsa assessment. All finished now thanks again.

I have been looking at lux testers and just wanted to know what sort are suitable for emergency light testing. I have seen such a leap from the cheap to expensive and just wanted to know what ones are acceptable to use, assuming they have to be calibrated.

Thanks
