reefnjunkie Posted January 6, 2016 Share Posted January 6, 2016 The 30% misread must be why I got such great growth color while running my frag tank at 175 par, I guess I was closer to 225. So does that mean Matts tank is 1800 par Quote Link to comment Share on other sites More sharing options...
Trigger334 Posted January 6, 2016 Share Posted January 6, 2016 As I understand it, the point of having more diodes is to improve the spread and reduce the disco ball effect. A great example is the Lani LED by Triton. I guess that would be the case, if your trying to maximize PAR, by using narrow beam emitters. In TMC's case, they use 120 angle emitters, with only 10 HO diodes. If there are wide enough optics to mimic the spread of a 15" or 20" mh reflector or a t5 parabolic then by all means let me know. The one thing leds really bring to the table right now over other light sources is efficiency and controllability. last time I checked the datasheets for every popular 3w led used in current fixtures they all hit their peak efficiency when driven at around 1w or 350ma. So to maintain that efficiency it is optimal to run a higher diode density at less current which also has the benefit of increased spread and light saturation. The one downside is the increased up front cost because of the increased diode count. I am not sure what circuitry issues a higher diode count would entail as long as proper drivers and power sources are used and as for moisture issues I know a t least one fixture on the market that is waterproof so with the proper design it shouldn't be a problem. Sent from my HTC6525LVW using Tapatalk The fixtures I'm thinking are TMC, which have 10 emitters 30 watts, all driven at 700mA. I'm not sure what effciency of each emitter is, but when I check on a couple of thm, they were designed to be driven at high mA and still maintain their lifespan. One problem with many of the fixtures with many more emitters, they don't have the proper circuity, especially when it comes to dimming and using multiple types of emitters. Many are just "daisy chained" like Christmas lights. With more and more diodes in these set-up, there is an increasingly chance of issues. Then add moisture that will get into that circuity over time... so while the quality of light is decent, there's construction issues I see to have a quality light set up long term. There are many different set-up/requirements. That I agree 100%. As far as a sole aquarium reef LED or diode... that has been out for some time.

TheClark Posted January 6, 2016 Share Posted January 6, 2016 That will be awesome. or You can spread out 100 Cree led on a 5'x5' aluminum sheet 1/4" and fire at 350ma or 500ma that should be less than 630.00 It is an interesting option. What mix of cree leds would you run Rudy? Quote Link to comment Share on other sites More sharing options...

TheClark Posted May 25, 2016 Share Posted May 25, 2016 I see they have more details out on their light technology including a rumored 'short wavelength royal blue' that is 5x more costly than normal royal blues?

goldenbasketreef Posted May 26, 2016 Author Share Posted May 26, 2016 Interesting, a combo violet and rb spectrum in one diode. Quote Link to comment Share on other sites More sharing options...
caolewis Posted May 26, 2016 Share Posted May 26, 2016 Thanks for the sharing Goldenbasketreef. I love new hi-tech stuff and might get that Philip at some point end of the year to try out. Good thread. I think I can make my corals work extra hard under LEDs :-) 2 Quote Link to comment Share on other sites More sharing options...

fishboys Posted May 26, 2016 Share Posted May 26, 2016 Just let me know what unit makes my corals pretty. 1 Quote Link to comment Share on other sites More sharing options...
Jorge Posted May 26, 2016 Share Posted May 26, 2016 Sounds like Phillips understands what our corals need . I'd try it now if it was available. Quote Link to comment Share on other sites More sharing options...
