Compared to the older 10w 70mm lights I was replacing these lights have a number of advantages. They are low latency ie. flick the switch and no discernible delay to them lighting up. I appreciate the switchable colour temperature choices within the same light. My previous lights were a fixed colour temperature. The larger 90mm size let me install plug ends because the cutout is large enough to fit them rather than having to hard wire them. Very pleased with and I used over 40 of them.
