Honestly, yes, especially in a non-CO2 tank. High likelihood of nuisance algae taking over after a few weeks. I would suggest a 6-8 hour photoperiod plus a max of 1 hour sunrise and sunset either side, if you want it, and would knock the intensity down so that it peaks at the level you have at 10:00, rather than going up to 100% on the whites.
But equally you can ignore this and just go with what you want, as every tank is different and it might surprise you! Just be prepared to watch closely and take action at the first sign of trouble.

Thanks for the tip! Yes I thought the 100% was a bit much (understatement when you have white sand!) so toned it down.
Edit: and I didn’t programme those times but condensed them into an afternoon / evening window.

As with any light set up you have to take into consideration the actual arrangement of your tank. There will be a definite difference in how much light gets to the bottom of a deeper tank comp[ared with shallower and also there will be a dramatic difference between an open tank and one with glass sliding covers. You only have to see how much difference windows make on how much UV gets through compared with 'open air'. In terms of quoted ligfht intensities I'd only take any notice of values that are measured in a real life situation and that have information supplied, eg distance from light to detector and if the detector is actually under water. Manufacturers should really be oblighed to provide at least gudeline values with and without a sheet of typical sliding cover glass between light and detector. The lack of really practical useful info with lights generally means you just end up experimenting with them and use whatever works best for yopur plants in your set up.
