@creamoh yung bridgelux china yan, pero okay din daw yan sabi ng mga gumagamit sa NR at RC, mas mura kasi yan di hamak sa CREE. Pag wala kaming ma-source na deep red at turquoise baka yan din ang gamitin naming brand. Kaso madalas talaga sa US kasi maka-cree talaga sila. Sa chinese brands, Epistar rin okay. At least sabi nung iba.

Pero regardless kung anong LEDs ang gamitin, di hamak naman na super efficient pa rin sila kung ikukumpara sa MH at T5s, at mas mura in the long run. Mas matrabaho lang talaga yung assembly at mas mahal ang initial cost.

Case in point, eto yung tank ko ngayon:
Image

21W total lang ang ilaw niyan sa ngayon. Yung MH ko dati na may lumenarc reflector, 150w. :lol:

@mazach recommended sa PAR38 ni boss Peter eh 15x15 (LxW), pero masasagad mo hanggang 18x18 yung spread kung medyo tataasan mo at kung hindi naman light demanding yung corals na ilalagay mo.

Yup, po-post ko sa thread ko yung light project. Padating na kasi yung hybrid multichips. Cree na lang talaga ang wala pa kami. Wala rin kasing budget. :lol:
Cheers,
Marty

Eto yung lights :D

Yung dalawa, binili ko from a sulit seller, yung isa (na nasa pinaka-itaas) naman binili ko sa CD-R King. Coolwhite lahat, modified lang. (5:2 Blue to CW)

Details here: viewtopic.php?f=21&t=15418&start=540#p198258

Modified din, hehe. Wala pa kasing downlights sa CD-R King nung nabili ko yan. (240 petot lang! :lol: ) Pero isang buo lang talaga yung lens nila, hindi gaya dun sa CD-R King na hiwa-hiwalay yung lens, so magandang pagtripan... pwedeng combo ng 30, 45 at 60 degree lens hehehe

@michuelo tinaasan ko ngayon, nasa 12" from the water surface. 18" yung height ng tank, 16" yung taas ng tubig. :D

@mazach pwede naman, kaso gaya nga ng sabi ko sa naunang post habulin pa rin dapat yung spectrum. Kung CW lang talaga as in ang gagamitin, maliban sa pangit yung kulay baka mas mabagal pa lalo yung growth kasi kadalasan sa mga CW, mataas ang green spectrum (combination kasi ng Red, Green and Blue ang Cool White at Neutral White LEDs, nagkakatalo lang sa kung aling kulay sa tatlo ang mas lamang), sayang lang kasi hindi usable ng zooxanthellae ng corals. Kung gagamitin mo siya as-is, ilapit mo na lang tsaka mag-supplement ka na lang siguro ng blue T5s.
Cheers,
Marty

@creamoh supposedly bro. Since underpowered yung LEDs. Malalaman mo yan kapag ginamitan mo na ng kill-a-watt or kahit anong watt meter yung LED fixture mo. May iba kasing LED fixtures na mas mataas pa rin yung konsumo ng kuryente kaysa dun sa stated nila sa label. Nagkakatalo naman yan sa drivers na ginamit.
