You cannot convert it. You have to guess, or spend about 4 grand for a PUR meter.
Yep, but like any lighting article written for this hobby, there's a lot of copy and paste information, without any real data to back it up.
I agree you you 100% mr.X. ....I look at it this way either spend 150-200 or spend 1000+ to get the same exact results.since owning the evergrow d120...which is the same exact thing inside and out as the Chinese eBay lights,reef breeders or any other no name company that's producing these 120 watt fixtures I have better growth on all my SPS dominant tank than I did with metal halides and T5's.BUT that's just my opinion.....Yes, but the part that I was commenting on was this nonsense-
[FONT=Verdana, Arial, Helvetica]*In another comparison; one can use one of the many cheap LED panels commonly sold that use 90-120 watts (or more) to light a reef or planted aquarium, OR you can use a LED Fixture that utilizes the best technology emitters & drivers available such as only found "higher end" LED Lights which produce more PUR from less emitters & watts.
This is similar to the above example as lower end emitters & drivers do not pin point the important light wave lengths the best patented emitters can (think about lighting your aquarium with 100's of LED flashlights; would you do this?).

I'd like to know exactly which units this guy was referring to and what were the results of his testing on that particular unit. I'm willing to bet the truth is, nothing was tested.
So does that fall in with the previous comments.. The emitters in LEDs do make a difference? Or how the LEDs are powered?
You must be aware that all LEDs are not created equal. Aside from their power capacity they also differ on what spectrum of light they emit just like other lighting fixtures. Some reefers say they don't care about the color of lights since they do not contribute to growth. My question is, isn't it that we love this hobby because the intention is to see the beauty and colors of the corals we are growing?
That makes sense. I know deep ocean photographers like you would even use full spectrum lights to capture the colors of the deep.I think it's up to everyone as to how they want the reef to look. I like natural, so I don't emphasize fluorescence. Some want that pop that a lot of blue can give.
