Respectable lux meter that doesn't cost $4k

[s_lannan]

Any ideas? Something of decent pedigree however....

[mcinque]

maybe a sekonic could do the job? It's a pretty respectable brand.

For what purpose?

Professionally any luxmeter with a valid traceable calibration certificate can be used, and the spectral validity with be on the certificate.

While we're at it, any recommendations for a cheap one?

Ballpark values, +/-10% would be fine (although 5% would be better). How accurate are these things anyway?

The accuracy depends on cost, price rises with accuracy < = 1% and/or much finer resolution in lux [0.1 lux or better].  Any meter that is calibration grade will be commercial grade even if you don't get a certificate.

For example, USA buyers for use in working and living conditions lighting evaluation:

$80.

With cal certificate, ~ 2x the cost:

ISO9002 is NOT a certificate of calibration...

[saturation]

For lux requirements in homes and workplaces, a meter of <= 20,000 lux or ~ 2,000 fc is more than adequate.  Even a resolution as low as 10 lux works, that's ~ 1 fc.  Most commercial meters can resolve 1 lux to accuracy better than 10%, as that $80 device.  Yes, the chassis can be cheap, but it gets the job done.

If you want a really ballpark figure and you have an Android phone there are free apps available.
Really, really ballpark though...

it has a vague certificate of calibration to ISO9002

I never thought of that.

Looks like there's quite a few apps available and they use the front-facing camera to measure light. I imagine they're not very accurate but the price is right.

They do not use the camera; they use the ambient light sensor used to manage automatic screen brightness.

Thanks for all the replies...
I wanted something that would verify a lumen output spec with a little accuracy... maybe less than $1000 worth of kit.

To elaborate our local supplier "Jaycar Electronics" has this nasty habit of promoting the standard shenzhen crap as "the ducks guts"......

What exactly do you want to measure? What accuracy do you need?
In many cases just a photodiode or something like OPT101P is adequate. There are many methods of DIY calibration that are reasonably accurate.

I have the BEHA UNITEST 93560 Luxmeter digital

Got it for a super deal on ebay
Retail is around Euro 150

[HighVoltage]

What TES model do you have?
I saw some with a sensor that looks that same but thye base unit looks a little different.
Here are 2 pictures on my Beha Lux Meter
