How much is the light loss?

about a stop with just the diffusion, about 2 stops maybe more with the diffusion and the grid, virtually none just using the box itself. it depends on how close you have the light to the back of the box. you can choke the light if it's too close

It will definitely not be enough light, IMO. Light does not penetrate very deep and the light itself is not very wide either.

It all depends on what you're running off of it. If its light I need to know the bulb or bulbs total watage.

I didn't use light loss was too grate for the lens I wanted to use it with wouldn't work with Cannon lens which would have been light compatible. Teleconverter halves light see if you want to use it at f12.6.

I don't have any numbers for you. I can only tell you that the difference is very small. From clear to a light smoke color, that's all your gonna get. Only about 20% Sun blocking power. Not much.

Not that great in low light. You will need to light the room a little, try a red light or something to have an excuse for lighting :)

The light is pretty warm, and natural. I'd say they would reach 2.5 meters. As my older lights wear out and die I'll replace them with this one for sure.

I don't know exactly how much but it isn't very bright, I have them set up on columns at the front of my driveway. It is enough to mark each side but doesn't give off enough light to illuminate around or to the ground. Basically just enough to show where to turn in.

That's around the size of the room i am using it in and it does very good at keeping it warm, I just got my light bill today and it has went down a little over $40.00 hope this helps.

Not sure...I have been turning the face away from me so there is very little light emitted.

Of course, but the light will dissipate so much you will lose much if it's effectiveness. Nice flash

I'm not sure but this model didn't put out much light at all. I never use it.

I'm not entirely sure. I haven't had any trouble with light reflections when I use it indoors, but I couldn't tell you how well it does outdoors.

No, it actually decrease it to something around 1.4 (on the blackmagic cinema camera it reduces from 2.36 to 1.53). Also you gain a full stop of light! i.e. A f/1.4 Nikon Full frame 50mm lens behaves like if it were a 35mm f/1.0 lens!!!

I am not sure! Light is very dim and not what I expected I would not purchase it again.

So far very good, no noticeable loss of light and I have it on daily for about 25 to 35 minutes per day while out on my walk.
