I know what scaru is saying and ive always agreed myself. Ill give a better example to better illustrate the point.
You can have a 2000 lumen halogen light bulb which emits light 360 degrees or a sipik sk68 which emits light at like 5 degrees with about 2-300 lumens.
Now if both were shined at your eyes which would hurt more? Of course the sipik68. Your eyes are a small part and therefore you want to measure intensity on a given spot, not total output where 99.95% of it isnt going in your eye. Get what i mean?
EDIT: I’ll use a better example.
Imaging a 2000 lumen lightbulb that has the ability to emit 360 degrees, and can be focused to 2 degrees but retain all the 2000 lumens.
When the light bulb is at 360 degree mode you can look at it without trouble, but if it’s at 2 degrees it’ll damn well burn your eyes out. Why? Because the light is more concentrated in the 2 degree mode, or as scaru is saying it has a higher candela (a measurement of intensity of light on any given spot).
