    GU10 LED Build Thread (Chinese Ebay Lights)

    They've been in for over a month. I'm going to reduce he lighting cycle to 1hr/day and increase it 1hr/day til i get to my normal cycle. will that work or should i take it slower?

    GU10 LED Build Thread (Chinese Ebay Lights)

    So I got everything all set up. I have 12 (6 white and 6 blue) bulbs with 60 degree optics mounted approximately 7 inches over the water of a 24 gallon, 19x19x19 tank. I got a zoa colony to test out the set-up and I'm really disappointed... They aren't opening up hardly at all. All of my water parameters are good so I'm wondering if they're not getting enough light. The 60 degree optics are giving me a great color blend but I'm wondering if they aren't getting enough light to my coral. Any thoughts?

    DIY GU10 LED Build

    Just wanted to start off my thanking TinyGiant for doing all of the research and sharing his experience in using these LED bulbs. Check out his thread here This build is for a 24 gallon JBJ NanoCube. I had been running it for about 8 months using the stock PC lighting and was very displeased with it's performance. My coral wasn't growing, had horrible color, and I hated the inability to create a dawn/dusk effect. Here's the tank pre-LED So after reading TinyGiant's entire GU10 LED build thread I decided to take the plunge. I ordered 13 of these GU10 bulbs from ebay seller led-hk. I was really pleased with his customer service and prompt shipping (It only took about 2 weeks from Hong Kong) GU10 3W White Energy Saving Bulb Colors: Cool White Shell material: Aluminum, zinc metal alloy Input voltage: 85-265V AC with reversed polarity protect Output power: 3.0W Beam angle: 30degrees Reflector efficiency: 90% Light source: 3 x 1W high power LED LED input current: 900mA Color Temperature: 6000-7000K Body temperature: <60°C LED working temperature: <65°C I ordered 6 cool white and 7 blue bulbs with 60 degree lenses. I was worried about getting a spotlighting effect with the 30 degree optics. Also ordered sockets and quick splice connectors Went to home depot and got supplies to build the canopy for the lights and started to build. (gluing) (brackets) Painted to match the stand Now onto wiring the sockets and mounting them into the canopy. For a detailed how-to, check out TinyGiant’s post, the link is at the top of the post. (photo stolen from TinyGiant) silicone over the wire to waterproof arranged in the canopy So I didn’t end up using the quick splice connectors. I tried using them and wasn’t able to get good contact between the wires so I went with TinyGiant’s method. I ordered some replacement legs for a CurrentUSA SunPod and heavily modified them to work on my canopy. Ready to go! Cool white only Blue only Moon light I took the lens off the bulb for the moon light for a wider spread through the tank. Final product With a couple of custom cut pieces of acrylic from Tap Plastic No coral yet so the results are to be determined. I love the way it looks and the dawn/dusk effect is amazing. I'll continue updating once I start stocking.

    Did you get the 60 degree lenses? I just got done with my build and I have the 60 degree lenses about 7.5 inches above my tank. It's a lot dimmer than I thought it would be... I'm a little bit worried that it's not going to be enough light to sustain coral.
  10. Would using a surface skimmer adequately oxygenate the water at night?
  11. Do you think that the PAR would be affected differently if the diffuser material was further away from the LED's? I'm asking because my plexiglass which is protecting the LED's is about 6-7 inches away from the LED's.
  12. I got one and i think i'm going to return it... the powerhead is so loud!!! anyone else having this issue?

    GU10 LED Build Thread (Chinese Ebay Lights)

    Got my bulbs in! I'm going to try to get everything up and running this week. For a 19Lx19w display should I go with 3 rows of 4 or 4 rows of 3... ie: WBWB WBW BWBW BWB WBWB WBW BWB It's a nano-cube, so your typical AIO tank I got the 60* optics as I'll only be mounting the bulbs about 5" from the surface. That should be enough light for me to be able to keep anything i want to, right?
  14. This might be a dumb question, I have no experience with reactors...Why don't you tumble the GFO and carbon together?
