With speaking to Brandon about this who works with current they have to post the bare minimum of what the light can do. Which can be many factors played out, current draw, amperage, etc etc. these lights absolutely produce a lot more than that one the sand bed of my 240 that’s 34 inches tall. That was also using a ly-cor 1500 par meter which is one of the top in the industries, and also comparing it with an apogee in a lab environment. Companies can not say they will hit 200 par at 18 inches or 24 or 36 because then how many people would attempt to claim false advertisement. My maximus clam is about 24 inches down and does great and has amazing colors. Which can be seen in my photos, and we all know maximus clams need more than 60 par to do well. Spec sheets state the bare minimum, to avoid people claiming false advertising

The reefbrites are good lights also, but why would she switch all three lights out? It also comes down to what her corals are use to, and if she likes the color of the currents or other lights. There are several factors to be considered when she is in this position. Switching lights is a common thing, but it’s also risky. It’s the same thing for example as an individual normally works 8am to 5pm. Then suddenly they switch from that shift to 10pm to 6 am. As humans we would definitely not approve and would make us unhappy. Corals being living animals get use to their environment and are not as flexible as us humans

@SamiBlue yes they would be more than enough on a 30 gallon tank.
