Question: Do i need to attach anything if i want to use this to hold my clamp lights?
Document: I purchased these stand to use with the CN-160 portable led lights, so they didn't need to hold up anything heavy. They came packaged well and in black zipped up canvas bags, which I thought was great. They are very lightweight. No damage to them and they work flawlessly. No problems at all. Would recommend these for anyone that are looking for a lightweight solution like I did. I am very happy with my purchase and look forward to using these in my future films.
One of mine lost its locking bolt at the tripod base on my first use, but with just a speedlight on it, it works fine. For going outside, make sure to attach a weight, and of course, if you attach too much weight, you'll probably bend it. But as long as you don't expect something super nice, and just want to get your feet wet with off-camera lighting, or you otherwise have a need for cheap, expendable equipment, this is a great deal.
I think that pretty much sums it up. These are the cheap, easy to use stands that we all need on hand. Don't expect them to hold anything other than a very light umbrella and a speedlight. But, they get the job done and serve a purpose.
I bought these to hold clamp lights and they do the job perfectly. Great addition to building a cheap light set up
I already own another pair of these light stands, so I knew what to expect. I would never place anything heavier than a simple clamp-on light, or small flash unit on one of these; that being said, these are perfect for small applications. They fit well into small, tight spaces, and with sandbags to hold them in place, they generally stay put. The bags that are proved are good enough, obviously, one can't expect too much for the price...
These stands are great. For a brief moment I contemplated building stands from PVC pipe. Do not waste your time! You'll spend maybe $10-15 along with your time, when you can get these babies for $28. Sturdy enough for my clamp lights, but I'm no pro. Not sure about the people who travel or not but I think if you take care of them they would hold up fine.
These are great light stands, my main use for these stands are with the Neweer CN-160 Led light.I got to say though that for outside windy condition i don't think that these stand would hold, get some sand bags and attach it to the bottom or something.
This is a good handy small set that is easy to move around. That said, it's only for small lights - LEDs or speedlights. Very flimsy and fragile, they will tip over. Sandbag if you want to risk it, but be warned. I only use LEDs and these are great to fit into tight corners or small rooms.
Very light weight, but then I use it with small LED lights. Not recommended for anything weighing more than a pound or two.
I like these light stands as they will fit in a standard suitcase and save me from traveling with a light stand bag and paying extra baggage fees at the airport. They are OK for use with speedlights and light weight umbrellas. They are not meant for everyday studio use. I would not want to mount any large or heavy mono lights to these stands. For traveling they are perfect as they fold down to 24&#34;. Highly recommended for traveling, just treat them carefully.
Answer: Clamp light? As in a cheap metal reflector with a spring clamp on the back? Then no, simply clamp it to the vertical post.
