Here is a review of the Karamy KLS-4220AL.
Karamy manufactures a range of light stands of different heights with the choice of 3 or 4 sections. The light stand we are reviewing here is Karamy KLS-4220AL, which can extend up to 86.6" (2.2 m), has 4 sections, and folds to 27.6" (70 cm). The family of the Karamy light stands offers a few interesting bells and whistles, but first, let's cover the basics.
The Karamy KLS-4220AL light stand is well-built. It feels sturdy, the quality of materials is great, and the black matte finish adds to the premium look and feel.
The Karamy light stands are air-cushioned. If you don't tighten one of the height adjustment knobs, the mounted flash will slowly slide down with a very little risk to be damaged. Many other light stands on the market have spring cushioning or no cushioning at all, but the ones with air-cushioning are the best to protect your lighting equipment. We tested the Karamy KLS-4220AL light stand with a number of speedlights and studio strobes, and the air-cushioning performed very well.
