We are looking at purchasing (2) 508a's but are concerned about the range of the light coverage -some of the paintings we need to shoot are 8 x 8 ft.

This a very nice light kit. My advice is if you are going to use at that distance, you should use it without a diffused pad. You won't regret to buy this light.

I don't think it will be a problem. I just shot a film and used this light as my primary and it worked fine- http://www.youtube.com/watch?v=H3kNwW75z88&list;=PL-jvR5L4qMbXdIod18v1BqQJf3_fkF74N&index;=4. Another light I was thinking of getting was the Aputure Amaran 528. Here is a video showing their capibilities- http://www.youtube.com/watch?v=abo-CgPjWo4

You should buy a 1'x1' panel and defuse it. To get that coverage would be impossible. You may even want 2 and out them on each side facing ce tee to make it even. They have some 600 led panels that are a bargin

Leh's response is right on in that there's no simple answer. In my use of the light, I'm illuminating an area that is approximately 100 x 100 (close to 1/4 acre) with the lamp mounted approximately 16' off the ground. In that area, any object or person is very well illuminated. If the bulb were higher, the are would grow a bit, lower and it would shrink - there is some sensitivity to mounting elevation.Overall, I'm very pleased with the coverage and especially with the cool white vs the more warm color of the sodium lamps.

Dump the crappy CFL's and use proper photo-floods. I use 500w photo floods and make sure the umbrellas are not super close. This is a really good-value-for-money setup. It won't last a million years but if you are doing casual shooting, occasionally, it is just fine.

My lfs has a comparable model. They recommended 6-10 in. Mine are about 6" from the water, I would adjust the height to get the correct spread and then adjust the brightness accordingly. In other words the higher you hang the lights the higher you should start your intensity

I have a 30 inch deep tank and the light coverage is fine for softies and Lps corals but the spa corals need to be up close to the fixture.

As long as your lighting the backdrop and you have a little distance between the subject and the backdrop, you should be fine.

No definitely not, way too weak a light for this size picture. You'd need a wider span light. Very flourescant blue typeLight so not great on an oil painting.

I use the Marineland plant light on a 18X18X18 cube with great success. I started with two to be sure of adequate light for the plants but two produced excessive algae so I stored one and use one.

It's difficult to shoot from directly above because of the light fixture, but you can get pretty close. I use museum wax to get the items at the right angle. I also loosely wrapped the light in tracing paper to minimize reflection.

One of these lights would work PERFECTLY for a 3 ' x 3' area! Using the math for the calculated light spread, you would be able to lower the panel to 13.5" of height and still have awesome core coverage to all sides of the room.

It will be tight, I would go bigger, barn method, if an 8 by 10 will work you really need a10 by 12!

Plenty of light for that depth. I would say enough for medium plants. You could probably also do the ray2 if looking for more alternatives.

these cover about 3.5' foot radius area at about 12 to 15 inches above plant with good growth, I eventually found they do great at 6-7 inches but coverage reduces to around 2-2.5 foot radius, most of the ufo styles have similar coverage , that will help you determine how many you will need. I think 2-4 lights will be good coverage ,,have had great growth and would definitely buy another

The picture size you describe would not be covered by this light. Perhaps you could use 2 lights if you want, that would cover it.

It is recommended to use 400 because it is more sensitive to light. You could use 200 but with larger apertures or slower times, which is generally more inconvenient.

I was able to cover 8ft by 12ft area with no problem, and I was making large thick cones. I'm sure I could have covered a much larger space if I had wanted to stretch it out more.

I'm using 2 36-48" lights for a 72" tank. I have full coverage but have to use two remotes, with 2 control panels - there is not an extra spot to join 2 into one panel.
