Will these lights work??

Forst one would only good for fish only or maybe low light softies in a shallow tank. These types of lights are usually inexpensive and inefficient 0.5W or maybe 1W LEDs with no optics. They probably work alright for plants when the plants are directly under them but not great for coral below the water. I'll believe the MH equivalency claims when they show them side by side with PAR meters. They seem a bit optimistic to me. The reason that real reef ready LED lighting is pricey is that it uses high quality and high efficiency 3 watt LEDs that cost more money.

As for the second fixture, those 5mm LEDs will not last long as they are difficult to cool. Most likely they will start to burn out within months. Love the marketing speak too. Wow, 6 centiwatt emitters. Thats 0.06 watts for each LED. Useless for any corals.
