I purchased an AI Prime but considering returning it before opening. I just started noticing in photos and Youtube videos using this light that it appears to have a very 'rainbow' effect on the tank that looks really un-natural. It seems like each individual LED color is showing up on the rocks and sand and they don't get blended together. If you use these lights, is this something that bothers you? Let me know if you have this setup and whether or not it works for you. I was going to be putting 4 of these a foot apart on a 5 foot tank but now worried it won't look good.
