The Law of Unintended Consequences – 6500k Wrap-up

What happens when a finishing room with 6500k bulbs has light spilling in from the hallway because the door is mostly a large pane of frosted glass? Do you cover the inside of the glass with black fabric?

Not me.

No, no, no.

I decide to change the hallway light bulb to 6500k. What happens next falls directly under the header of “The Law of Unintended Consequences”…

You see, my room is at the end of a hallway – so changing the bulb outside the door solves the problem of mixed light temperatures filtering into the edit room. But when you walk down the hallway, suddenly that one light fixture stuck out like a sore thumb. It’s a lone brand-new bulb shining in its glory – a full 3000 degrees hotter than any other light in the hallway.

In a world of dull orange lighting, the bright blue bulb became an eyesore. The next step?

That’s right, I changed all the bulbs in the hallway to 6500k. The hallway brightened considerably (I figure the previous bulbs were at least 3 years old and were quite tired).

And then came my co-workers headaches. It seems the new bright blue light filtering out of the hallway and into their offices was mixing color temperatures with their 3000k orange overhead fluorescent lights. I’m guessing the constant white balance adjustments their brains were forced into executing tired people out.

So, what’s a geeky finisher to do? That’s right…

We installed a total of 25 6500k fluorescent lights!

All this because I wanted a properly lit edit suite and didn’t want to close in my already small-ish space by covering the door with black fabric…

  1. […] Color Temperature: Why control color temperature? Read this 2007 post from my company’s blog which explains why I implemented industry-standard lighting for my color correction suite. The rationale stands to this day. Back on that blog, I posted a few days later about a much more succinct reason why industry-standard lighting is so important. And if you want a chuckle, read how my lighting decision had some unintended consequences. […]
