chinese led lights

[jeffesaurusrex]

Shimmer lines are apparently shorter and "Wilder" with LED because of the multiple light sources. Natural sunlight gives the longest calmest lines, and halides while closer than led to natural sunlight are still shorter and wilder than sunlight.

I do have a question though. I'm planning an 80g, 48x24x16. I wonder if I would need four lights because of the double width, or if I could hang the lights higher to get more spread without affecting par too much due to the shallowness of the tank. Any thoughts?

[jeffesaurusrex]

Double. Whoops!

If the aquariumleds are running at 350mA, and 3.5 volts, how do they get 3 watts? 350mA seems kinda low, but I'm definetly not an led/electronic expert.

The taotronics specs state they run at 630mA and consume 131 watts total. Which would equal 2.38w per led at 3.78v.

I purchased the 120watt light from aquariumleds to compare to my apollos. There is no comparison. The unit is way dimmer than the apollo leds. I guess at less than half the price of an apollo its not too bad.

I would love to see some videos of the aquarium LED models...

It is very difficult to take pics of LED lights without them turning out very blue. They dont look as blue in person as most pics that you will see.

On another note, I dropped one of my units in my tank, so if anyone was wondering if they are waterproof the answer is no.

I have it all taken apart and think it may be salvageable, I emailed aquariumeleds to see if the can sell me a new driver since i think that is what got fried. Will let everyone know how that goes.

Also, no heat sinks inside the unit.

I dont think anyone intended for that kind of test, good to know...

A side by side pic of both units over a tank to show the difference would be awesome. Or if you only have one fixture over your tank a before and after.

Found this on alibaba:

http://houyi.en.alibaba.com/product/...time&edm_ver=e

She said fixture price as follows:
64x3W Cree=458+112shipping
or something comparable to eshine
40x3W Cree=388+82 shipping

Fixtures include hanging kit and legs, and of course that sleek built in controller.



I have this Light fixtures. They works perfect and looks perfect. I order 24" and 36". http://www.youtube.com/watch?v=OsSgT...eature=channel

Anyone heard anything about these? I like the looks of them.

My 250 watt mh are currently 8 inch off the water line. Would I be able to run LEDs at the same height and get decent coverage on a 75 gallon tank?

All you guys posting about your 1 watt LEDs need to recheck what this thread is about. The guy who started this thread was referring to the eshine fixture with 3 watt cree. Those china made fixture with 1 watt LEDs are not very good lights for sps and there is se horrible reviews from them. If your looking for a cheap alternative to expensive LEDs you need to get the eshine ones, at least they use Cree LEDs which have been proven to grow nice corals.

No this thread is about eshine led system that's use Cree led. Those 1 watt less system don't work man. If your going china make sure your system has Cree les at least.

[dojic60]

Light fixtures I posted Is 3W cree its not 1w. China and not China everything is China today. Cree led is now made in China.

Yes Cree does have a plant in China however all of its High effeciency chips are still made in the Durham North Carolina Plant. The Chinese plants are assembling the PAR light bulbs. and several other of their lighting fixtures.

[BigAirHarper]

dojic60, nice looking setup you got there. I'm really liking the looks of those fixtures too.

Could you give us some more details about the fixture as well? Like how long you have had it, and more importantly how that controller is working out for you to simulate the sunset/sunrise effect?

I'm ordering my lights this week for my 57 so it's getting crunch time.

Yes, and then the thread evolved.

Although technically the thread was started about Chinese LED fixture in general, with a direct question about those specific fixtures.


The thread stopped being about the OP halfway through page one. Hell, it stopped being about 1 watt LEDs for the most part around the same point.

What about the KEY LED K3 fixtures? If an eshines light is running roughly 280$ + shipping, and is only 60 watts, what about a key fixture which a 36inch one will run around $630 shipped to the usa with what appears to be 148 watts with the sps power bar...

It appears to be somewhat programmable too

[GroYurOwn]

yeah , i think the thread is about whatever the thread is about on page 21 as opposed to page one! and now its not so much about whether or not they are crappy, but which one to buy!

[GroYurOwn]

Also, aquariumleds.com said he can't get the dimmable LEDs because of the Orbital patent issue.

A $630 fixture at 148 Watts comes out to $4.25 per watt. or $12.77 per 3 Watt LED. if you have any do it yourself skills at all you could reduce that cost by about 1/3. But more importantly you could customize the lighting to your personal taste.

However there is the issue of time inoilved for the build and how much do you value your time. A build like this would take me about 8 hours so I would look at as working a job that payed $26.50 an hour.

Patent infringement is starting to ba a bigger issue every day. A lot of the research that went into LED's was Patented by US Companies like CREE. While all LED's are dimmable there dimming is realy done by controlong the drivers so it should be the drivers that are limiting them rather than the actual LED's. Interestly every driver I have purchased to date has "Made in China" stamped on it someplace.

However we are talking about a complet fixture here would have a total patent as well. So the possibility that someone holds a patent on the fisture itself with this feature is a possibility. If that is true and Patiernt rights are observed than we should only have on vendor world wide that offeres thes feature on there fixtures. Untill someone comes up with a completly different method of dimming LEDs.

I still think we are on the topic. If we are going to compare the prefirmance of Chineese fixtures we need to compare them to everything on the market to only be fair. This includes the American made fistures as well as home built fixtures.

How would feel if you thought you bbought the latest and greatest Chineese fisture only to discover that it fell short of an American made fixture that costed less? If not for patient laws I could easily start a small company competing with the Chineese building a limited number of fixtures that would be superior and cost less today. My R&R costs would be minimal compared to the US companies alredy holding the patients and I would not have to worry about revovering the heavy R&R and legal costs.

Just think if Customs were to check every imported product against patient rights in the US how much would be turned down at the port of entry compared to what is turned back today which in the muli millions.

good points you pointed out to us troptea !
I've learned alot more about leds in just a coupple of pages , well done.

what do you think of this chinese eshine system's fixture i just bought (see attachment)

aquariumleds.com is working out of Canada though (right on the border actually), not sure if that makes things more difficult for him, patent wise, or what.

I use to work for a product design firm. And if you had a good lawyer that knew what he was doing, that filed your patent - it's hard to get around it! Put it this way, there is sometimes more money involved in buying and selling of IP (intellectual property) than the actual products themselves....lol

I've been lurking around on this thread and got to looking and comparing. I too found the same ones on Alibaba and got a quote on the 48" HY-A01-240Watt for the 8' 450 I'm putting up. I only need 2 units according to them which with shipping puts me in at @1267.70 including shipping. I've got a 165 now and I will test them out on it and see if I think this will do the 450. Currently I have Maxspect g2's on it.

The only other one I am waiting for a quote on (but I think it will be more than I want to spend) is the PHAROS which has itself listed on alibaba. I should have a price on them tonight. I know they are being sold by US retailers for around $1149 per unit and I would need at least 4 so I want to see what kind of a deal the manufacturer will give me.

I really don't think that these chinese black boxes are such a bad deal because face it all the big name lights are built in China anyway and then again in another few years there will be something "new and better" that we will all just have to have and lay out more $$$.
