My current led is just a generic 120 watt basic model, that is 3 years old. I’m upgrading to a newer model that is full spectrum , dimmable, with a digital timer in it. so, the question is should I start out at 50% blues and 30 % whites or can I start at a higher percentage and less duration?. the light is a oceanrevive t247 I am getting.
Is the new light also 120w? you can usually find ratings in lumens, PAR or something to compare the fixtures. I don’t think it would hurt to start low and ramp up slowly. It can hurt if you go full blast if its a more intense light. Even different spectrums as in your case are advisable to do slowly. So, IMO, yes start low and gradually turn it up. If you find corals begin to bleach, turn it down.

+1, also very easy to bleach the corals with LEDs if too high output.
maybe i miss read but this would depend on the coral in the tank. sps would not like the lower light at all. but if its mainly softies like zoas a good 20-30% white and ect and 30-40% blue would be a good start.
SPS are more susceptible to changes in light intensity. It’s considered safer to give them less light than more light. If there is too little light they might start to brown out, but the colors will return when the intensity is increased.
