If the strip isn’t as bright as it should be, check that it is properly set up. Its brightness may be less than expected if it isn’t firmly inserted into your chosen 5V USB power source, or if it doesn’t have enough power for the strip. Make sure the strip isn’t torn or damaged in any way. In addition, you should use the remote to see if the strip isn’t already at its highest brightness setting. If it isn’t, increase the brightness to a more suitable level. If your chosen area is extremely hot, cold, or humid, then the strip may not operate at its maximum efficiency.
