How many of your fixtures would you say for a265 gallon 7 ft x 30"deep?

john reefer · 03/03/2013, 04:38 PM

I have a IT 2080 light and need to change some of the lights. It came with some of the white on the blue channel in one corner so I need to change the position of six of the LEDS. What do I need to do to change them? Thanks for any help you can give.

You need a soldering iron, thermal paste, and some 1mm solder. A pair of tweezers helps for placing the diodes.

Ok what is the thermal paste for?

hillscp · 03/05/2013, 07:43 AM

It creates a heat transfer connection for the led. It's the same as the paste that sticks a computer CPU to the heat sync.

john reefer · 03/06/2013, 04:04 PM

I have some extra leds from when I bought the light. Just looked at one paste under the metal on the back. I"m fine w/ the ones I'm moving, but the new ones how do I know + - or does it matter? If I need to test them how many volts are they? Thanks a lot! I feel much more comfortable moving my lights to the right channels now.

hillscp · 03/08/2013, 07:55 AM

Yes the + - matters. I have not seen those emitters but I have strung LEDs before. Have you sent RB an email? They should be able to answer. Most stars have plus minus clearly marked and idk if they are in series or parallel.

They aren't on stars, they are on legs. The easiest way to tell, is that the fatter leg is - I believe. They are in series.

You can check the direction of the diode with a multimeter. If you put the leads on and get a low resistance then the red lead is +. If you swap the leads and get a higher resistance then the red lead is -. I hope this makes sense.

yes, also there is an obvious (-) marking on that leg. bad picture but you can still make it out.

JP Reef · 03/08/2013, 09:29 AM

I personally always check with a multimeter. I have gotten LED's labeled wrong before.

Dapg8gt · 03/08/2013, 09:33 AM

The pic above shows it.. Also the bags they send them in have a pic of +|- for reference.

Reef_Breeders · 03/08/2013, 10:28 AM

We clearly label all of the LEDs with a spectrum, and + and - sides, and put thermal paste on the bottom. The - on the leg is how we ID them pre shipment.

john reefer · 03/08/2013, 03:54 PM

That helps I see the - . I think I will test them as well just to be safe. None of them have paste, and the only markings are on the papers there in. Not original packaging. I will have to find some paste soon, and see if I can mess up my light. Thanks everyone for the input.

hillscp · 03/08/2013, 05:37 PM

You can get the paste at a computer store. Overclockers use it and any nerds on call wagon will have some on their toolbox if you want to hold one up

MJNTWise · 03/09/2013, 09:19 AM

Does any one have the link to there stock lay outs? We at TBRC are getting ready to do our second group buy and I would to order there d120 with there stock full spectrum layout.

Thanks

lol I do have one in mind.

Hello

I live in the UK but have been able to source an IT2080 LED fixture. As you know , it is 36" long and has 90 degree optics.

My tank is 48" with a brace bar in the middle and I'm quite worried about this and the spread of light from this unit on my tank.

Do you guys have some advice for me? E.g. how high will I have to have the unit to get light to both sides of the tank? Will the brace bar cause a *huge* shadow or un-noticable (like my T5's at the moment). etc etc

Appreciate any guidance you can offer before I commit to buy.

Chicago · 03/12/2013, 05:06 PM

hows the latest update on the new ree breder units.. out?

I have a 2080 on my 72 inch tank w/ a 4 bulb T5 on the other half. My led is 12 above the tank to the bottom. I moved it over to get the spread you want, and it got pretty dark at the end of the tank. I have two cross bars w/ no dead spots. IMO you should get two smaller lights. They have one more row wide of LEDS. Hope that helps.

grandp10 · 03/13/2013, 07:16 PM

As far as width the 32" actually has 2 more rows. Front to back the 16" has 1 more row.

ChadRaay86 · 03/14/2013, 12:29 AM

I posted this on the other Evergrow forum, but wanted to see if anyone here has anything different

I have a D120 that seems to have gotten the channels mixed up. Two of my three fixtures have the channels set up where one channel is all blues and the other is white/colors. For some reason my third fixture has it setup where 1 channel is half blue and half white/colors and the other channel is the same. Thus I can't ever run just whites/colors or just blues which makes 1/3 of my tank look different from the other 2/3.

Does anybody know if there's an easy fix for this? I don't want to send it in and have to move all my SPS from that section of the tank.

Thanks!

reefer4unme · 03/14/2013, 12:57 PM

I have a stupid question ....(only cause I'm new to the led world)are the optic lens holder measurments 14mm high by 20mm diameter?im ordering optic lens and I want to be sure these are correct

Sounds like you would have to rewire it unfortunately.
