Personally I'd be nervous about that particular bulb. Although they are Bridelux LEDs and 3 watts ( which actually doesn't matter) they must be old lights that the original company couldn't sell. Now the Chinese manufacturer is rebranding them and people assume they are newer versions than they actually are.
I say this because the lights use very old and inefficient LEDs that are pushing a dim 60-70 lum per watt.
So, if you get them, remember you will require more watts than a modern Bridgelux or Cree powered light would need. But it still should work for a 10 gal
tank I think.
