GU10 LED Build Thread (Chinese Ebay Lights)

Thanks for the quick reply! I'm thinking about go with some of them over a square tank, 24x24x12. Gonna keep mostly softies maybe some LPS. I'm thinking these would work well for my application when I finally get it up and running.

should be great. I have tons of sps, clams softies and poylps under them all with awesome success..

 

i'm glad people at paying attention to these... i read for a good month or two on the cree and par bulbs before deciding to try these out (rather spend the 10-20 bux to try the bulbs than 100-200 on something very similar.

 

i was so impressed with the bulbs that i got on the first run that i decided to do the whole nano with it.. and eventually my 55g.

 

a friend ordered two par 38" and i really didnt like them. my tank is brighter and far more balanced and natural in color. I spent $150 total on my whole light setup for a 55. he had about $225 into his 30g. and he had to mount those lights so far above the tank to make it look "okay" mine are about 9-10" off the top of the tank

Does it really take 2 weeks to get them from china? Or is there someone in the US where i can order them?

I am pretty sure if you want them that cheap you will have to wait. I have ordered the 3-1w blues and they work pretty well and are very cheap.

Just ordered 2 "test" bulbs in the blue for sh!ts and giggles. Could you post a picture of the bulbs above your tank as well?

 

Thanks.

thx for the cool info. I just ordered

1pc GU10 85~265V 4W Blue Energy Saving Bulb 4x1w LED

1pc GU10 85~265V 4W White Energy Saving Bulb 4x1W LED

5pcs GU10 LED Halogen Lamp Wire Connector Socket.

 

just want to test these out before i commit to making a custom canopy for my 20L.

 

I wonder how many I would need to cover 20L. its 30*12 so im guessing maybe (since its 30degree optics) about 6 to 12 inches off the surface and about 10-15 of these.

what do you think?

what kind of cord are you wiring these to? I notice theres 2 cords coming out of the socket do I need to hook them up to separate parts of a wire? are these like + and - or something. Im trying to understand this, but im terrible when it comes to electric stuff.

yeah

 

wire all the negatives to the negatives and all the positives to the positives..

 

google wiring parallel

15 bulbs.

 

figure one for every 2 inches is more than fine. or do one less than one every 2 inches.

fwiw it could be cheaper to use chinese leds and drivers but set them up in a diy fashion like other led setups, but the thermal performance would definateley be better

i thought of that too.. but this is far easier. For those who want DIY but not have to ask a million questions or deal with a bunch of drivers and such this it :)

keep in mind too these aren't over driven most of them are at 350ma so they should run cooler and longer than most people are running the crees. I have noticed and light loss. At the price even if a few do have issues the savings would allow for some replacements here and there :)

it comes down to thermal resistance and total heatsinking area..i have a few single 3w bulbs that i use around the house and they get hot..but youre right, for the price it might still be worth it if you only get 20k hours out of them

i ran 9 of mine for about 5 months without the optics on the nano.. i wouldnt recommend that since the optics keep the led board secured to the thermal paste. I lost on due to over heating (the led chip hanged off the heatsink..

 

other than i've had great success and results with them :)
