  • Works Great But Not Instant On
Number of Items: 1
It served its purpose at a reasonable price. My 4’ linear LED light fixture is working again. I chose this one because its default values were close to the values of my old LED Driver that failed. I don’t have a way of programming an LED Driver. I took away one star only because it’s not instant on. When i turn my light switch on, my other fixtures light up instantaneously but the fixture with this driver has about a 1 second delay before lighting. Not a deal breaker, will just take some time to get used to. ... show more
