GU10 LED Build Thread (Chinese Ebay Lights)

Recommended Posts

I bought 30 of the 4x1w bulbs, I had him put 60 degree optics on them. I have 15 white, 15 blue.

 

To be honest, I don't really like them very much. Perhaps just not my cup of tea. Not sure what I'll do with them.

 

I think one of my LFS is interested in buying them, but they are not sure.

 

If anyone here is interested in them, let me know. Mods, if I'm not allowed to post that, I'm sorry and please remove that part of my post.

I ordered on the 6th. Still waiting. Not being able to track is driving me crazy.

 

Led hk blues came today(their estimate was at latest in the 2nd week of sept). I was surprised actually. I ordered a day after you.

The whites with tracking still have not made it onto us soil according to tracking. Still "origin post is preparing shipment" on USPS. The tracking has dissapeared from ems post.

A) the lights be strong enough?

B) will there be lazer beam effects?

what are the over tall lengths of these bulbs?

 

3w bulbs is about 2 1/4", 4w 2 7/16", 5w ~3"

 

The past 3 or 4 times I ordered bulbs from LED-HK, they got here in 10-12 days.

 

Lalebeq, since they are on order, you can judge for yourself... but I'd say if you remove the optics, the light is going to be pretty scattered and weak in comparison. as far as the spot light effect, if your water is clear, you won't see the beaming effect.

YEEEEEEEEEES. arrived today.

 

haven't fired them up, but the heat sealed in ESD bag is a nice touch.

Wow. I'm equally unimpressed with my 4x1s

 

Lame.

1. Tiny, I almost lost our bet as I worked on the wiring while plugged in. I was so distracted and suddenly I realized and went "oh crap". No zaps, so far I still owe you a frag.

 

2. After checking all the new bulbs i noticed a smokey smell, like wood burning. It could be cause I just screwed down new sockets to the box. I was unsure so I just unplugged it.

((edit)) I soon realized the smokey smell was all of the upstairs, turns out my grandmother put on the heat. That was probably the smell.

And lastly, although I was only testing 4x1w blues, I can say they're pretty lackluster compared to my old 3x3w. However, since both 3x3w failed fairly quickly (1-2 months? They'll still light but only for 60sec then a dimmed flicker) that the 3x3 should not be an option.

Is this a good reason to stick with the 3x1w bulbs? I've planned to order 40 bulbs, 20 blue and 20 cool white.I don't want to order something I will be "unimpressed" with!

a member of the local reef club that i run was begging me for a custom hood for the gu10.. so i started working on it today.

 

 

I just have to order some more sockets and the bulbs, wire it up, install two fans and a couple strips of LEDs for moon lighting

 

here are some pics:

Great idea and it's looking good Tiny!!! I was actually planning something similar for the 125. My idea is to have an enclosure that the bulbs come out of vs hanging down from... I guess an upside down box.

I was wondering if i should go with some warm whites since my tank is a macro tank? I was thinking of doing 4 x 1w with 2 warm white leds and 2 blue leds in the bulb.

 

Any thoughts on that?

 

thanks

No. I think from what Ive read 3x1 are dimmer then 4x1 or 5x1

I'm comparing to 3x3 with different optics which obviously Would be extremely brighter/different spread.

However, after heat issues very quickly would not remmonend 3x3 in a small form factor (maybe 3x2 are ok? Or large heatsinked 3x3

Gotcha! I'm ready to get some ordered, but hesitant to pull the trigger at this point. If the 4x1w 30 degree bulbs aren't causing issues for anyone, that my be the route I go then. With my tank being a 125 (72x18x24), I want something to penetrate that depth to have decent PAR on the sand. If there's not that much of a price difference between 4x1w and 5x1w bulbs, I may try a few of those too.

 

Thanks for the recommendations!

Tiny how many of these do you think would be enough for a 12x12x12 Mr. Aqua Cube 7.5gal

 

i am building a hood right now with 14-16 of them in a 12x12 foot print.

 

should have a good spread on it :)

My first chinese shipment ever to have issues :(

 

Item has been stuck after passing chinese customs for 17 days, and has not been moved into the US yet. Total time in transit isnt horrible (23 days) but based on tracking info I think this is lost. Seller wants me to continue waiting due to university/colleges just starting.

 

In fact the tracking for china air states "Tracking Information Expired

The tracking data on this shipment has not been updated in more than 10 business days by US Postal Service. Please contact US Postal Service for more information."
