Bro Jacky,
Confirm your white balance is out.
Your LR should not be this color unless visually you see it this color also
This is what many of us face when we start using LED
It take me more than a month to find out what go wrong
I think if the spec is as claim, then for easy to keep SPS keep it above the mid level of your tank or
6 inch from the LED.
This is only a general guide based on SSC,Cree and Luxeon leds.
Hope it is true for your LED also
Its ok.Because never see something so low before from most of the leds I had being using to date.
So sori if you feel you are being bombarded.
But I think info share need to be correct right?
I am not concern about the overdriving.
No one will do that.
Overdriving an led reduce its life greatly.
I am more concern about claim.
As there is no led spec.
We do not know at what ampere we need to drive this led before we can get 160 lm.
Please take note the same led will give you less lumen when drive at 350 mA and at 1.4 A
Only through manufacturer spec then we can know if the claim is true
