Opinion on these LEDs please

I am new to lighting requirements for planted aquariums. I found these LEDs on Ebay, item number 140914029931, and they seem too good to be true. Would they work for a 150 gallon, 72"x28"x18", planted aquarium? If so, how many would you recommend?

They also have Item number: 140887845643 that seem to be much better.

I recently went through the process of getting learned on LEDs for planted tanks. A lot of research out there an in the past year more & more suitable products are now available. Many first attempts failed miserably in my opinion what what I've read. I came to the conclusion that you get what you pay for.

In the case you site from eBay they list only white light at 5600K. That's not going to be sufficient as the plants need a range of colors & wavelengths in specific spectrum ranges. Also no mention of the optics (what degree angles) or the PAR (photosynthestically available radiation) that the plants need to turn light into energy to metabolize.

I paid for them let me tell you but I purchased (4) of the 30" Freshwater LEDs from aquariumplants.com (but they are built by BuildmyLED.com). I have a 135gal long (72"). Now I wished I would've gottent the 36" versions due to a center of my tank shadowing effect but BuildmyLED has been very customer service oriented and is building me a center piece LED set to fix that issue. Go here to learn what qualities LEDs should have to be sufficient to grow any medium to high light requiring plants.

But for smaller lower light requiring tanks (low tech) they may work just enough & are cheap but I seriously doubt they would yield great results. Maybe algae would love them!
