Light meter ?

Hi all

I’m thinking of getting a light meter to play with, as it’s on the company account I have the choice of the following three

ILM-01 £86

ILM 1337 £86.50

ILM 1335 £98

As I’ve never used one before I’m not sure if they are any good or what i should be looking for ?

I use this one

reads close to everyone elses, so I think its good

The last one claims a much higher max light level 400,000 lux.
Adding an ND filter should increase the max on any meter but having less need for a filter might be nice.

Thanks Chris, that’s cheap !

I thought they may be junk at that price point but It appears not, ive got a few items in my fasttech basket at the moment so I may just take a punt on that, cheers

The best thing I like about the FT meter is it uses AAA batteries. The worst thing is the sensor is not detachable. There's a variation of this meter on ebay that's similarly priced, but has a remote sensor. I haven't tried it though. I went with a much fancier unit, which unfortunately uses 9V batteries.

Android or iPhone app work physics tools?

I used the iphone app… luxmeter or something; it’s not very accurate. I was getting 15-30% range of readings just by taking a measurement, waiting a few seconds and and taking another with all else constant. Not horrible if you’re just looking for a very rough estimate. *Using a new iPhone 4s

The accuracy and range of luxmeter apps depends entirely on what phone your using.
I believe there is a thread on it.

Yeah my son downloaded it on his iPhone 4 and his reading were a lot lower than what I got with my Galaxy 4.and it didn't go as high either but as long as I can get a ball park figure its better than just looking.

The 2nd meter only goes up to 20K lux, so it’s out. :slight_smile:

My Nexus 4 already does 10K lux, and is good enough for basic measurements. (output drop over time, etc.)

I’d go with the 3rd one as Helios had stated.

All three are overkill for our purposes though, IMO.

what does that set-up run?

It would be nice to blow off most of these low budget meters, of questionable accuracy, and just have all agree on using the far more widespread use of your “in camera” light meters in F stops?

A “Bugetlight” standard ceiling bounce or gray card/wall shot at X amount of distance at X settings. Sort of like beam shots but using a standardized setting that anyone with a camera can duplicate and compare to a point.

Spend more money on lights!
