VW_TDI_02 Posted March 21, 2015 Share Posted March 21, 2015 I'm looking to get a LED bulb for my sump. I'm not running a refugium so I'm going to turn that middle section which is currently empty into a frag tank (reason for more corals...). The section is about 14" from left to right, 13 inches from front to back, and about 8" deep. The color on these bulbs isn't ideal but I can't afford to go off and get some $60+ bulb that has more blues. These run a 2:1 ratio of whites to blues and should be able to grow corals just fine even if they may not look the best under these lights. I'm NOT going to be doing any SPS corals and will be collecting mostly zoas and LPS frags. My options are 15,21, 27, and 36 watt bulbs. Each of them is running 3 watt bridgelux LEDs. http://www.ebay.com/itm/15-21-27-36-54W-E27-LED-Aquarium-Light-Bulb-Coral-Reef-Tank-Grow-Lamp-Blue-White-/371260324892?pt=LH_DefaultDomain_0&var=640388536379&hash=item5670d6fc1c Link to comment
VW_TDI_02 Posted March 22, 2015 Author Share Posted March 22, 2015 Ended up not ordering it because I couldn't really decide. Anyone care to help?? Link to comment
ajmckay Posted March 22, 2015 Share Posted March 22, 2015 I vote the 36w... They don't seem to hit their "rated" consumption anyways so actual output will be less than that. I've never used one before but it looks very similar to this one and he reported decent results after using it a few months. http://www.nano-reef.com/topic/342698-26-ebay-par38-led-36w-bulb/ Link to comment
jedimasterben Posted March 22, 2015 Share Posted March 22, 2015 EDIT: Nvm, thought you meant refugium, the one you have is ok, but don't expect great color or a long lifespan. Link to comment
jbb Posted March 22, 2015 Share Posted March 22, 2015 You don't want it to be similar to display lights, you want red. If you need cheap, then look at this: http://www.ebay.com/itm/Full-Spectrum-15w-21w-27w-36w-54w-E27-Bulbs-LED-Hydroponic-Plant-Grow-Light-Lamp-/141277776616?pt=LH_DefaultDomain_2&var=&hash=item20e4cfcae8 Don't expect much lifespan out of the higher wattage ones, though. Why red for a frag tank?? Do you even read the actual questions ? Lol Link to comment

VW_TDI_02 Posted March 22, 2015 Author Share Posted March 22, 2015 I put an eye hook into the top and put a loose knot in the cable to hang it. This way I can adjust how high I want it. The tank itself is 40" tall, sump is 4-5" off the ground so I'm looking at about 25-30" of room to work with for the tank. One more question, I found the following bulbs that include a pair 517.5nm green LEDs, ship from china (negative), and are slightly more expensive. Would these be worth it the extra price and wait time or should I just go with the blue and white ones I listed above? http://www.ebay.com/itm/21w-27w-36w-45w-54w-E27-LED-Coral-Reef-Plant-Grow-Light-Fish-Tank-Aquarium-PAR38/151455888006?_trksid=p2047675.c100005.m1851&_trkparms=aid%3D222007%26algo%3DSIC.MBE%26ao%3D1%26asc%3D20131003132420%26meid%3D533673d5c02144e58b29041cc9a35c58%26pid%3D100005%26rk%3D1%26rkt%3D6%26sd%3D310973094685&rt=nc Link to comment
jedimasterben Posted March 22, 2015 Share Posted March 22, 2015 Just adding green doesn't really do anything other than make some disco. You want the white LEDs to be at least neutral, if not warm, and include some regular blue (460-470nm) in addition to royal blue (440-450nm). Link to comment

In that case I think I'm going to just get the 36 watt version of the one I linked originally. Link to comment
