Normally I do a ton of research on stuff like this before making a purchase, but reefkoi has such a great deal going I have to jump in and make my purchase. What do people think? I like the blue look, but I have heard the 20k is very blue. And this will be going ever a 40 breeder, so not much water to absorb the light.

Really just looking for personel opinions, so anything would ne a big help. Thank you!

Murf, your tank is the only one that I have seen running these lights. I like the color a lot, but since it is 300 gallons does the extra water drown out some of the blue?

Randomfish, what size tank are you running these over? And does it still have a blue tint? Or is it pretty white?

Thanks again guys.

I don't think it does. It does take out some of the PAR though. Your PAR would be higher so you would still have to shade any Acans and Chalices.

i have the 20k and like it ...i have seen the 14k and like those too ...lol

im not sure if you can run just white or just blues on the 14ks though because i think one driver has both whites and blues on it ..but i could be wrong

All great information guys. Thank you. I think I'm going with the 20k. I would love to come check out some of your tanks some time. We will have to arrange something soon. Thanks again for the info!

so to add to the confusion ..i have the 1w 20k and i love it but we had the 2w 14k at the masc meeting raffle last weekend and i thought it was pretty blue
...so has anyone seen the 1w 20k vs 2w 20k side by side and is there a difference ...

2w being what he is selling now but i believe some of you are basing your opinions of off the 1 watt lights which are different even though they are also labeled as 120w as well

they look the same to me, you might see a little different shade of blue in the new 2w but the ratio is 40-15 which in 1w terms is 80-30 and the old 20K are 85-34 so its just as close to identical as we can get.

I hate making these decisions Haha. So far I have to go off of what I have seen, and that is the 20k at murfs. The wife and I both loved the color he has. Chris, do you happen to have a 14k at the house that I could look at on Saturday?

I dont have any 14K lights here right now but we can take a 200w dimmable over my frag tanks and adjust the color so you can see what they look like in 1:1 white/blue which is the 14K ok?

That sounds good to me. I think I'm pretty set on the 20k after a lot of last minute studying Haha, but it would still be cool to see the other one for reference.
