Hey ive read this whole thread. i have a 120g fish only saltwarer. No corals. All i was looking for were some lights to give bright intense shimmer like Metal halides do. My tank dimensions are 60x18x28 high. I ordered 2x 30w 20k led
flood lights. I have a center brace.
I have them laying directly on glass canopy and not much heat is being produced or transfered. Pretty cool on the glass side. I think the light is enough to light my tank especially fish only. Is it intense? NO!. Is it replacing 250MH No. Would they grow a sps
28" down i doubt it.
But that doesnt mean they are bad at all. They are perfect for someone who doesnt want to change bulbs be it t5 or MH
. They illuminate well and fish like chromis pop well under the blue hue of 20k.
I called ebay seller and he's awesome. He said that because of my tall tank and extra foot long i should upgrade and allowed me to send my 2 30w back. He sent outs 2x 50w and 12k. Prior experience tells me that a 6500k-10k-12k will be brighter then same powered 20k or blue light. So we bumped down to 12k increased wattage to 50w and also threw in 2x 30w actinics to make up for lost blues in the 20k-12k drop.
Im super psyched because the tank looks like it has dual t5ho with shimmer now. With extra leds and extra wattage and brighter kelvin i believe it should be much better. But ill know for sure tomorrow and will get back to everyone.
