cree led

[funkmaster]

i feel that cree led lights are the best out there does any one know if 3 watt 6700k is the way to go and how many white and blue lights will i need for a 150gl ank 6 ft x18x24

From what I have read and researched you may want to look into Luxeon star leds. IMHO.

I was wondering the same, is it okay to go with the 6500k or should I be looking for the 10000k???

I have several fixtures, all running Cree XR-E Q5s, Cool White and Royal Blues. Pots were added to buckpucks for dimming each color, this allowed me a good range of color. Recently, I started to use the Meanwell driver (up to 13 LEDs), the version I have requires a PWM 555 circuit to dim (5%-100%). There's another version of the same Meanwell driver that can be used (as I have read) with Digital Aquatics ALC module.

I'll be using the same amount of blue LED's and white LED's with dimmable drivers. that way I can vary the color and find what I like best.

The Meanwells that I think you are talking about end with a D and you can also use them with the Profilux controller. This is something I am looking into and will be trying to build soon.

emmanuel, would you happen to know how many lumens each white LED you used puts out?

im relizing more and more that people really dont know about led lights its more trial and error .......maybe more then its worth

Please define "best"

does any one know if 3 watt 6700k is the way to go

well I think only marine scientist can tell you what's the best color temperature for your coral growth(i am guessing here as you have not mentioned why you have choosen 6700K for)

and how many white and blue lights will i need for a 150gl ank 6 ft x18x24

Most DIYers use 50/50 approach while some diyers like 2W:1B ratio mainly for the look

happy with mine

 

[emmanuel]

I love mine too just. Wish I used more blue than 50/50
