Which is better for lighting up a room by ceiling bounce: a light that floods or a light that throws?
Would a certain tint be generally better for providing more illumination by ceiling bounce?
I’ve found that a light which floods will illuminate better through ceiling bounce. Not sure why, but that is just the way it is for my light meter.
A tint preference is hard to guess, but I’ll say NW is easier on the eyes than CW, seeing as though there’ll be a bright spot on the roof and anyone who stares long enough will get green spots in their eyes.
I find a thrower lights up the area under the beam most bright then less bright the further you are from the hotspot while a floody-light lights up the room more evenly.
Would the battery type affect whether throw or flood is better for that light for lighting up a room by ceiling bounce? like AA, 14500, 18650 for instance.
Or would flood or throw be the deciding factor for room illumination regardless of whether the light is a heavy duty or EDC light, or being run on high or low?
Battery type wouldn’t affect the throw or flood capabilities of the light. I have only been in need to do a ceiling bounce in order to illuminate the house maybe once in two years, and have found that even at “low” (let’s say less than 50 lumens) in a room such as the dining room or lounge room (where no one is expecting to read anything), your eyes adjust well to the low light, and thus extending the run time of your light. On the other hand, if you expect to do other activities such as cooking or reading, you may be more inclined to use a headlamp in those situations.
Personally speaking, because I have a lot of AA’s in hand, I would prefer to use my AA based lights to light up the house despite the fact that my 18650 based lights do produce longer run times at their “low” setting.
Real throwers seldom exceed 1400 lumens, but these lumens are concentrated in a small area to achieve long throw… Flooders routinely achieve 2000 to 5000 lumens projected in a much wider area. The more lumens, the more ilLUMENnation, so a high-lumen light will always brightly lit a room in a ceiling bounce.
