should i get D-Suny lights

[David martin]

Hi,
sorry if this question has been asked before, but I'm a completely new, I have a 4x2x3, and i have just found some lights called D-Suny, are the any good? there are two sets, one has had 18mths usage, and the other set is untouched there is 4 light panels, x2 controller panels, and x2 power units £350 is this a good purchase many thanks Dave

 

[Reefing Madness]

Yup, your good with those.

I have a 2 panel 4' set with wifi and it seems to be doing a great jog.

Now that I said that our maintenance guy reported one panel has some lights dead. LOL

Will have to check it out at home tonight.

 

[David martin]

Thanks both- I don't know if these are Wifi, as one set is 18 mths old, has there been many changes to these lights

 

[beaslbob]

you can check on ebay as there has been upgrades through the years.

 

[beaslbob]

FWIW I haven't used wifi on ours.

Further update, we upgraded and the new hood is not as tall as the old hood.

The particular dsuny lights I have each panel is ~2'x6-8" and does not have a cooling fan. It just uses radiation to cool.

I think in the new hood they installed the lights higher or closer to the top of the hood which cut down the cooling area.

Therefore, the lights are running hotter and 2 channels have failed in one panel in less than a week.

But that shouldn't apply to an older system. You might check to insure all leds are operation just to be on the safe side.

I would just get a new 32" SB Reef Light

I'm using the panels with the built in fans and they are brilliant you can find them on ebay new for cheap. I know the panels without fans tend to overheat and burn out

sound like what we're gonna have to do. Things were fine though with the taller hood. then with a shorter hood over a 90g (vrs 60g) it only took one week for a panel to burn out.

This are what I'm using. Currently using 2 over my 4x2x2 until my 6x2x2 is ready to fill

There are 2 type of light
1, no-fan version; the advantage is best cover, so there is no tiny shady spot in your tank, even at the corner of the bottom. And it also save 35% energy power!
if there is good air-flow in your tank cover or there is cool fan in the cover (like red sea tank for there no-led light). I strong suggested this version.
2, fan version. : the advantage is more strong in same area under light.
if deep tank or you do not care about the power consumption, I suggest this.


the newest marine version of them as following.

Maybe you see there are Red and Green led base on that version.

There is really some one want red and green, so we do that version. I do not think the red is useful for coral grow.

just an update: The panel the failed had some cold soldier on the controller cards. Meanwhile the new panels and older panels on you new 90g have been trouble free for a couple of years or so.

Yes, it should be .
Please do not hesitate to message me if you need "my hands"


BTW, In fact, there is only 2 type from the view of compatibility of electricity.
1, fan version
2, no-fan version.

each panel of same type should be compatible with each others, no matter the versions. even marine version with fresh water version.

As I remember there was an Oliver they forwarded me 2 as the technical expert. It that's you Hi! LOL

 

[Oliver@DSunY]

Yes, it me

 

[beaslbob]

ok Hi then. LOL

 

[Oliver@DSunY]

;Playful Hi.

Hi from Italy.
I bought 4 panel no-fan version for my 500 litres, 140x60x60. I think it's good quality for the price, the project it is excellent.
I bought online and received in my country in 10 days.
thin panels , no fan and so no noise, low power consumption, perfect spectrum for corals.

 

[Oliver@DSunY]

Congratulation!

Please 4 pcs 54cm panels for your 140x60x60 tank, it is best cover. I can sure there is no tiny shadow even at the corner on the bottom.

private speak, I think you choice a prefect lighting solution for your tank.
you can think the fan version as a strong spot, the no fan version as a flat. your tank is only 60cm deep(high). no fan version light can good work for it.
if we think about fan version, you have to face some part is too strong (under the light), some part is weak (between panels). or you have to add more panels for better optical uniformity. which means cost more power consumption. As we tested internally, same effect. no fan version will save 15-20% power energy compared with fan version .
Please think about the the light is more then 8 hours every day. it is really big cost for a year.

Please if your tank is new tank or first configure LED, I suggest run the "slow accalamation "mode 1-2 weeks to let the fish and coral slow suitable for new environment.
Attached are chart of the accolamation mode.

 

[Oliver@DSunY]

you see it bright latter and dark early, there is no moon and only 80% bright at noon.

Enjoy the light
