citibank does not do 3 d secure.. so can not use that card to do payment with aliexpress. nuts... so now simon at twilight suggested paypal.. do they do paypal at alibaba.. otherwise known as aliexpress.. is it safer than credit card.. i have never tried so hard to give a seller money..

nuts

bhazard451 · 07/25/2012, 12:45 PM

Paypal is very easy and secure.

klipprand · 07/25/2012, 01:08 PM

They have a promotions for these lights and for two of them at 36" they come out little under $600. Any reviews?

I wouldn't trust the "Crees" in these. They list Cree temps and colors that Cree doesn't even make (violet). The generic bridgelux leds might be a better buy.

No one has tried them yet, I would love to hear if someone has.

Ten33 · 07/25/2012, 02:11 PM

Thank you all for having the testicular fortitude and trying out these lights while keeping us informed on the progress.

I think I'm going to try the D120's for a 90G.....

secrest · 07/25/2012, 02:29 PM

I'm really glad I found this thread. I'm going to place an order within the next day or two for this d120 : http://www.aliexpress.com/store/prod...586764753.html

Is there anything special I need to request when ordering this, such as optics or anything else? It's going to be a over 40 breeder.

Ten33 · 07/25/2012, 02:51 PM

One question, when they say it's "Dimmable" for the d120 does that mean it can be done with dials on the fixture or a seperate controller is needed?

terancevan88 · 07/25/2012, 02:59 PM

Knobs on light dim it

You can request them to customize it any way you want. If you wanted different color leds, optics, etc, they can make it for you.

downbeach · 07/25/2012, 03:44 PM

I just did a GB with e.shine, and when I questioned them about the "colors" I was told that the color's used, i.e. UV, purple, red, green, etc., other than a couple of different whites or blues, were all epistar emitters.

As far as the standard Bridgelux emitters are concerned, my original LED's which were similar to these 120W (55 x 3w) that are being discussed were Bridgelux, and worked fine. I liked them so much that I chose them over the Cree offering for the same new fixture I just installed. I really believe that much of the price difference between them is in Cree's licensing fees.

bhazard451 · 07/25/2012, 05:21 PM

First impressions of the Twilight fixture are not good. The White leds are extremely dim, even at 100% intensity by themselves, and the blues overpower them completely. With the ratio I used, it makes it look awful.

Either I'm not getting enough power to the whites, or they are using some terrible Epistars in this. The d120 and Nova are much brighter.

Not what I wanted to hear. Going to finally get mine tomorrow. Have you contacted Twilight on this?

Wow that's sounds bad. Im so glad that I went with the d120's and a4's. I hope others appreciate all the extra time you have put in to this thread. You really help keeping people informed.

It looks like the total cost will be almost $750 for two of these lights if not more and that seems alot for aftermarket lights. Any thoughts?

does your tank have braces on it? if so this is something to consider because i have a 6ft tank and went with 3 nova a4's because of the braces in my tank

my a4's got here today!!!!

i have wired them in a series so all my blues turn in at once and my whites then come on all at once. its a nice feature to only have 2 plugs going into the sockets.

anyone have any pictures of their units hanging from ceiling NOT in a canopy? mine will be coming from the ceiling with no canopy and I'm looking for a way to hide all the cords etc.

Not what I wanted to hear either. Mine should be arriving in the next week.

Yeah that is one of the reason I wanted to get two A8 instead of the smaller ones or even two a6. The center braces makes it very hard to position the lights so that it is not coverd by the braces. Do you have a picture of your setup.

redadeath · 07/25/2012, 06:14 PM

can any body tell me wich is better
this fixture

http://www.aliexpress.com/store/prod...512988624.html

or this one

http://www.eshinesystems.com/aqua/4g...ium-light.html

biecacka · 07/25/2012, 06:18 PM

i havent hung mine yet because I'm still trying to figure out how i want to do it. the reason i went with the a4's over the a6 or a8 is the a4's fit perfectly over my 24x24 openings created by my braces. i have to braces creating 3 spaces 24x24 and the 3 a4's fit right in there and will light them well
once i get them up and running ill take and post pictures

I have a 180 watts LEd from my LFS, is better build, has a nice heat sink, and for i was told a better fan,s, the best thing is that is one year warranty in house
The problem is that i move from a 30" long tank to a 48" and i would love to get one of this chinnese ligths after reading this whole trhed, just not sure how to complement the one that i have all ready, is 30 royal blue and 25 20 k white
any suggestions?

bhazard451 · 07/25/2012, 06:31 PM

I'm going to give it a few hours to see if maybe the whites will lighten up a bit, but so far I'm extremely disappointed with Twilight's fixture. I'm running each channel at 100% except for the moonlights, which are just 3 more royal blues.

The arrangement of leds isn't blended at all. Notice how the left side of the tank is blue, and the right side is more red... ***.

This is a closer view. Color is something above 20k and completely unnatural.

Leds just placed randomly. I thought they would at least blend them.

This is the Apollo SolarBlast fixture which shows a much better blend, and much stronger leds.

The last resort is to try to lower the blue channel to like 30-50%. I may just remove 20-25 leds or so and replace them with better bridgelux ones. Parallel strings be damned. I'd rather attempt it than get stuck with how this is currently.
