LED strip lights have been around a while. These battens have lots of uses, and it seems that many are good for one function, but they may not fare well at another. Some didn’t use 4-in-1 LEDs, some didn’t line up perfectly in a row, and my biggest pet peeve — none of them could ever illuminate a whole backdrop evenly, from top to bottom with just a ground row of fixtures. Then along comes this product from GLP.
