chinese led lights

[bhazard451]

If anyone wants a d120 type unit with no optics and multiple colors, I'm selling my Reefbreeders fixture. Barely used. PM if interested.

If you start going over $300+ per light for a chinese fixture, you're better off buying a commercial fixture in the US with a better warranty.

I agree with you I think the ones in the $200 price rage are a great price.
But as soon as they start geting in the $300+ plus range i would spend more and go with the Maxspect Razor R420R It has the latest Crees with build in timers ect

If this is for your 75 gallon tank remember you tank is only 18" from front to back. So with the 60 degree lenses you still have a 29 inch spread with the lights 6" high at the substrate. At the surface you will have less coverage but the main idea is to light up the corals rather than the surface. If you end up with dark spots or shadowing to an excess you can move the light fixture further to the front of the tank and angle it to point at the bottom rear of the tank. This actualy creates an unbelievably nice shimmer effect as well.

Thanks. I think I will still contact Lyn to see how hard it is to change the optics if I want to later.

The 20" R420R is great for the price. Especially with 10% off code at Hellolights.com $359.95. Wish it had the same amount of leds as the 27" fixture though.

Would you like some green eggs?

So the LEDs in the links posted don't come with any kind of controller?

Sam said 199a4 through the 20th!
Troptea if I get 3 a4 on my 220 should I get 60-90 degree optics. It's 30 inches tall. I think 60. I don't understand the spread part of them you explained earlier

From Simon:
In theory, the 60 degree optics cover a tank over 70cm in width, if you hanging the light 50~60cm above the bottom of the tank, so I think 60 degree optics is OK.

Simon told me 60* optics cover 47x56 inches...

Damn, my lights are now on sale!

[AcroBluz]

Has anyone recieved a set of lights with the controller yet to see how user friendly it is? I personally don't need a controller besides my Alex to turn it on and off but I was just wondering if the built in controller is more hassle then it's worth to program.

Guys I've got to say I love my light! I got this http://www.aliexpress.com/snapshot/108940417.html and I was worried it was going to be too blue but they are so adjustable! No regrets here! Thanks to this thread and all the info to help me make the decision to get it!

We don't know yet. What I do know is, that the fixture is on sale this week with a 10% discount, so if you haven't ordered one yet, now would be a good time. Saves almost $30, and they won't adjust to the sale price if you bought one already.

My lights arrived today!

[bluesox_68blues]

Ok so these were with an Iphone and it really doesnt do the light justice but you can see pic's and videos here.

Also if someone could help ID 6 and the top of 12 that would be awesome! Like I said its not that blue in real life but my corals do pop. I think I even get more shimmer then my 250 mh. Hope you like!

[bluesox_68blues]

Also for anyone looking at the video picture 22-23 were the old lights

[levischilz]

Are any of them controllable via apex?

[cmantis]

I need to build a light stand. My tank will be on the top of a shelving unit so I was thinking I could use pvc and drill it and use screws to hold it to the sides of the four posts. Then it will go up about 30"s and over to hang the light over the tank. I will use T's and elbows to tie it all together going over the top. Do you think this is doable? If so what size pvc should I go with (will 1/2" be enough)?

[dsdaley77]

Number of panels: 1

[cmantis]

Two will be enough but I would use royal blue which is more like 445nm and add some violet 420nm.
