flood light LED's
 
I'm going to take the plunge in LED's for 3 of my planted tanks, hoping to get some advice. Been reading alot about the Finnex on here and that seems to be one route alot of people are choosing. I came across a post on my local fish forum from someone who purchased LED floodlights from China. This company doesn't specialize in aquariums, just regular lights. He posted a video of his reef tank here.

The company he bought from was http://zxl-lighting.com/

Has anyone tried this company for LED lights?

You can find the same thing on the various auction sites, as well.

There are a few tank journals here on TPT that utilize those LEDs. May want to search them out.

I bought 1 via Ebay from LED wholesalers to use over a 20G. Cost was $35.50 (including shipping). I wish I had not bought it. I floods the living room.

Many of these LEDs can be dimmed and it's more than simple to prevent light from spreading outside the tank with shields and such.

I got a 30w of this type of light, from a US seller with a plug. It's spectrum is around 5k, but it's pretty nice to look at. I did add a 2-3" aluminum foil shroud to cut down on what Hilde is talking about. I hung it high over a 20L, it should be bright enough to grow whatever plants I want. I'm still setting up the tank though, so I can't tell you how the plants grow, but I do plan to start a thread on here for it.

The 10w version, from what I gathered is around 900 lumens, so mine should be cranking over 2500.

I had to splice a 3 prong cord, which was from a PC, onto mine. If you have to that let me know and I'll help you match the colors.

I would like to see a picture of the aluminium shroud. Seems something that could be done in a short time. Working 2 jobs my time is limited.

I'm interested in getting two 10w floods for two 10g tanks but was concerned with both the Kelvin and light spread being too wide. How high did you both hang your fixtures?

Here's the tank pre setup.

Mine says 4-4500k on it. it was sold as white, but for a 30W with a plug it was the only option, it's actually not very yellow. I'd try to get one sold as "cool white" should be close to 6500k. The shroud, was taking some "great value" aluminum foil, folding it over ~3 times-in the desired width, trimming it to the right length, then scotch taping it to the fixture. It doesn't get very hot so it should be fine for now. IF you rest it right on the tank, the spread won't be an issue though. I plan to have an emersed grow box behind the tank(the black thing), plus it's just one light and a 30" tank-that is why I hung it up high.

HEINEKEN357: Any shots of the 10w you're using?

acitydweller 10-30-2012 01:26 PM

im debating on whether 10w will be enough or 20w will be too many lumens on a 10g.

most of these auctions on ebay show a 3 wire setup and i noticed some are also DC only (likely for car and boat applications).

Was it as simple as wiring up the black/white and red cables from the lamp to a power plug or did you have to use a transformer

The 10w should be enough, but if you can spring for the 20w, you can always raise it, or add floating plants.

I suggest filtering the results to US sellers, and maybe add the term plug to the search terms. The plugged 10W should be around 25 bucks total, and the 20W should be around 35.

Yes just the colors were:
Yellow/green to green
Brown to black
Blue to white

10 gallon with 10 wat LED flood light

james1542 10-30-2012 04:08 PM

Someone should start a LED Flood club thread to showcase all the tanks putting these to use.

somewhatshocked 10-30-2012 04:37 PM

Or just use the search feature...
