Am I the only one that still has to think in watts vs lumens for light bulbs for brightness?

Only reason to measure watts is to figure out your lumens to power ratio otherwise it's just lumens.

But if you grew up knowing the brightness of a 60 watt bulb and you bought 60 watt or 75 watt, that became the defacto measure of brightness

And then they started doing different types of frosting. Bastards.

Sry dude, I grew up adopting cfl bulbs early and switching to LEDs as soon as I could, so I've been pretty much using lumens for a while, I can't recall the last time I bought a regular incandescent.

They don't even sell IC bulbs anymore down here. But I still am thinking "I need a soft 60W for the loo and a clear 150W over the workbench" and then I use the lookup chart at the hardware store to find a suitable lumens range.

Ya know you're right. I'm wrong fuggit they all have the og wattage so really it don't matter.

Not only, Clint. But, it's really better/more precise to use lumens measurement + colour temperature. Cause nowadays wattage of LEDs differs. So, lumens help to avoid confusion & misunderstanding.

I get why lumen as the unit is better. But I need a table to go x == 75w bulb :)

I use only ≈ 3500K colour temperature, just simple neutral white (it also called „warm white”). For my eye it's perfect fit for home.

75W classic lightbulb ≈ 900 lm. Plenty of tables in russian, belarusian language. Just translate, rewrite in english & save for further usage:

And have to remember which colour temperature is cold/blue-tinged or warm/yellow-tinged
