LED floodlights at my kids kindergarden….

I noticed these LED lights outside my kid's kindergarden:

They seem to pack quite a punch, and some of the more powerful ones are rated from 4400k to 5000-5500k and are not too expensive.

Was thinking wether they would be a nice substitute to tungsten open face lights…? They rate them at 80 lumen / watt, giving a 50w lamp 4000 lumens. You can even get them as high as 200w ( 16000 lumen….).

Maybe I should try and snap a photo when I get over there tomorrow to see what kind of exposure is possible with the 30w they have installed.


EDIT: to give you a price hint… I can pick up the 70w (5500 lumen) for 630 dollars including Danish tax.

I think where these might present problems are flickering and a low Colour Rendering Index (CRI). You could test flickering by pointing a camera at it. CRI is a bit harder to measure but there are tools out there to do it but none of them look cheap.
