Where to buy a light of flux or ppfd meter cheap

I’m hoping someone can tell me what kind of light meter I will need to test the levels in the best way, I’m not sure and haven’t a clue, I can place my lights correctly then

The hydro shop i use sell a digital lux meter for £45 google digital light meter and you should find one. I should think one of those would do the job.

@Tom I could be mistaken, but as he references PPFD in subject, I don't think he wants a lux meter, rather a quantum meter that can read PAR.

 

@platinumbud instead of saying "cheap" could you put a budget down, one person's cheap could be another's food for a year, it's too subjective a term :)  I know there's a few chaps on here who have these meters, I'm sure you'll get assistance :)

 

Edit: I copied my own text for ya...have a search on me, you owe me a cookie :)

Lumens are a measurement of how much visible light is seen by the human eye, you need a PAR/PPFD meter for measuring plant light intensity as already suggested by Unity. :)
