flood light LED's

[acitydweller]

powerstrips are usually about 2 meters but i went with a cord for 3 meters. just gives ya more flexibility for mounting ooptions, incase hanging was considered.

You could try Dollar Tree ($1 store) or Dollar General for a 3prong extension cord.

I've got a 10W round model on the way (6500k)-looks pretty snazzy. One ebay listing said it is submersible-not that I'm going to do that. I'm going to put it over my emersed grow bed on my 20L.

This is the one, allegedly yields 900 lumens (I didn't go for the RGB with remote that costs 10 bucks more):

I want to see this one hooked up. Once you get it going could you tell us how the light spread is? I'm looking for something with a tight beam so that it doesn't spill out all over the living room. I also like my tank to have dark edges.

I'm also wondering if the RGB model will allow you to mix the colors to produce white? I'd like to turn my tank blue sometimes.

can you (and HEINEKIN357) please post the ebay id from which you bought it? I'm really interested in these for my med-high light 40gB but I'm afraid to make a bad purchase

Here is the id for the 10w led 290550124424 and here is the id for the 2x20w led fixture 200831281622 I would go with 20w leds or the 2x20w fixtures.

Did a par test for you guys (par meter is diy that hoppy helped with) Hope it helps.
Measured from the meter to the light open air and right under the led.
10w led 6500k
12in 51par
15in 33par
18in 24par

20w led 6500k
12in 140par
15in 100par
18in 66par

Is that 12in from the substrate or above the tank?

Your welcome..

Readings are from the substrate. I measured from the meter to the light open air.

How did you do the DIY par meter? Is there a thread to this?

I'll post some updates when I get it. The little white button with a W on the remote I believe is for "white" it could be something around 6500k but who knows.

Thanks for sharing those par values gojirador, it does appear the 10W should be reserved for really shallow tanks or med-low light conditions.

@heine,
Thanks for the par data. It is par with my findings as well. I intend to use the 10w on my 10 gallon tanks and two 20w on my 55g temporarily as I save up for my finnex Ray II. Budget is extremely tight so I couldn't purchase on blackfriday

First of all, I'm new on this forum (but not new on fishkeeping or aquarium on general). But I'm very interested in replacing my T8 fixture with leds and those ebay floodlights seems to be sortof cheap and intensity-efficient.

@heineken(really nice beer actually..)
is it possible that you could provide PAR data also off center, I mean like two inches and four inches away the hotspot right under the led.

@ anyone
What would you think, would I end up with medium light or low light with five ebay 10W floodlights. My tank is 45 inches long and 16 inches wide with depth of 18 inches. I'm planning to fabricate a fixture with those five 10W floodlights spaced evenly on the lenght of the tank.

[Sethjohnson30]

I think you would be better off with 3 20w fixtures at that depth

[acitydweller]

dare i say go with two 30W fixtures...

[james1542]

Welcome to the forum Jarpii, my best guess, the 10 W LED's would give you medium-low light(if they are closely spaced, I suppose their output could add up to high light? If one is 24 par, 2 should get you 40par , 4 should get you 80par, but that is if they are really close together with all of their beams overlapping), 3 20's would be med-high, 2X 30W's would give you high light at the substrate, you also have the option of 1X 50w, you might have low light at the ends of the tank but you would definitely have very high light in the middle.
