GU10 LED Build Thread (Chinese Ebay Lights)

Easy remedy for that is order the 60 degree optics. Thats what I did. I have my bulbs about 2 inches apart and once I changed out the optics problem was solved. The only thing is you can only use them on the 4-1w bulbs just send HK an email and ask for the 60 optics. I got them for 1 dollar each shipped.

hey Tiny, wanted to say thanks for the heads up on these bulbs, my corals are loving them. I'm going to be ordering more for my new build, the 40B but was curious what you would recommend as a total count? I'd prefer the 2:1 ratio on the blue to white, using the 4x1w from HK_LED. thoughts?

i would say do 36 total since you have a bigger floor space for the 40b ..

 

do like 18 bulbs across in two rows staggered

 

or start with 20 and see how you like it. i would say 36 would be the best maybe a little less since they are 4w

I am thinking about adding a few blues to even out my diy par30 lights over a 12gal long . Does HK sell any with the 60 degree optics already assembled? I read here that only the 4 -1w blues can use the 60 degree optics, is that true? I am not really looking for brightness, just something to even out the coverage between the par30's. Maybe even the 3-1w with the optics removed might be an option. Suggestions?

I am just looking to fill in the somewhat shaded areas between the par30's and on the ends. Maybe 5 bulbs if only using the blues. I get the ideal color (for me) by partially covering one of the white leds on the par30's but I am losing a little overall light by doing that. I am hoping that by adding the blue gu10's I can uncover the white par30 leds and have the same blueish color with a little more overall light.

I've unfortunately had to open an ebay case and then escalate it as I only have 3 or 4 days before I can no longer request assistance from ebay/paypal. Every correspondence with the seller is "please friend wait a few more days". :unsure:

The seller was good, and got it in the mail fast etc... it's just the package is most def lost and he's either delaying hoping it will be found or resolution date passes.

If anyone has extra whites let me know. I'd like at least 6 to get the ones owed to my buddy (at the very least) I feel wicked bad for making him wait so long.

Sorry no extras...

Just get some from led-hk, I've ordered 3x and recieved them in about 9-12 days.

I'm very close to ordering some of the lights for both my pico set up and 35 hex. I'm a little confuse on the ratio and amts of bulbs to get. I would think a higher ratio of the whites to blues would be better suites for the coral growth but from wht I've read it seems like most set ups have a higher ratio of blues to whites. Is that for the benefit of the corals or just an aesthetically pleasing thing? And if anyone has any suggestions on bulb counts for those set ups?

TIny,

 

First. That hood is awesome. I was thinking about doing something simular to that but was going to make the lights movable... well not movable but there is some kind of lighting socket here in korea that lets you angle the light. It stays flush with the bottom of the fixture. I didn't have time to do it. But this is awesome.

 

Secondly. What optics do you have on these lights and aprox how high is this fixture above the tank in these pics?

Please excuse my lack of electric diy knowledge but would this type of cable be suitable to wire the sockets to? Or did you use something different?

Also, if this is the cable, is there a limit to how many lights you could wire per cable? I don't want to burn my house down :o

 

 

Thanks :)

That cord will work fine. As far as limits unless you are hooking 50+ bulbs to it you should be ok

 

Hey! Thanks so much for the quick reply :) I really appreciate it.

 

I'm currently in the starting stages of planning my first sw tank (22 gallon). I definitely think this is the best lighting option :)

 

Thank you Tiny Giant for telling us about these, your concept has inspired me to upgrade my current tank lighting!
