Wow slappy had the lights higher on the tank today ,the blue leds .I think it must be the secret to them lovely zoos we see so often in the states.
you should see the colours wow .

hope to have some pics for you soon

ok, email me the pics whenever you can.

One other I realised, the lights run directly from main 240 volt so not a good idea to put them into tanks with closed hoods where moisture will get into the terminals.

Best suited for open top tanks. :wink:

[jason@jasonsaquatics]

Good point ,Im looking for a water tight way of doing it .Maybe a closed system with a perspex slider to keep out the all to well known splashing

Could work but perspex or acrylic will need constnt cleaning other light will not penetrate properly resulting in poor quality corals.

[jason@jasonsaquatics]

Im sure we can come up with some idea .Think waterproof.

Anyone have any ideas on how to keep a none waterproof unit dry .We are useing a 1.5w 240v led bulb with a none waterproof fitting .
The unit is easy to fit on an open top tank with a wall unit ,
But to keep it dry on a tank with a sealed lid is another question .

Its worth the effort working on this one as the corals like zoos look like the ones we see so often in the us tanks .Slappy has seen the leds on the tank and they give you that shimmer like you get with the halides .The red brains zoos mushrooms and a lot more corals looked stunning .



Ideas on this would be handy

is it just bog standard blue led's?
if so what about xmas fairy lights..
i have some external blue led lights which were only cheap

[jason@jasonsaquatics]

There a g 10 unit i think .

But there nice and the colour it gives the corals is tops .If i can get my bro to take a pic of the unit i will .Also a pic of the corals with and without the light on them .

Might be a few days

It's a GU10 fitting and runs direct from 240v mains, so no transformer hence the need to water proof the units for closed top tanks.

Open top tanks isn't the problem.

I've ordered 2 and will order spot lamp holders soon.

[treeboa]

if there are no user serviceable parts why not just bed the lot in silicone, if not because of back heat then pot it in resin

[SLAPPY]

That's possible but I've abandoned the idea for the minute.

Hi
Jason dropped in yesterday and logged on today.

I using a Lunar-Cast Lunar Cycle Simulator.
Unit LED only lasted a few weeks and packed up.
Was replaced FOC so I waterproofed the unit.

I had an old UV Steralizer clear tube into which the LED fitted.
I then purchased two rubber bungs for just a few pence from a brewing shop and cut a slit to take the wire one end. A light smear of vasaline to make a water tight seal and no problems. It is secured with two cable tidys in the aquarium hood only an inch from the water and is very easy to remove for cleaning.

Hope this helps.

Roger.

reading this whilst searching about the pro's and coms of led lighting?
i've always used halides and narva tubes but now i have the nano im determined that the lid is staying on!

are these a specific brand or will any waterproof led's work the same and makes my LPS and zoos 'pop'?

i have been looking at these twin 12" long units
http://cgi.ebay.co.uk/TWIN-12-inch-15-LED-...1QQcmdZViewItem

or even these triples
http://cgi.ebay.co.uk/TRIPLE-12-15x-LED-10...1QQcmdZViewItem

bare in mind the size of the d+d 24 gallon tank
i would prefer conformation before wasting any money?
thanks guys

[SLAPPY]

I've not seen those ones in use before Wayne, but seeing as you are using them in a nano tank with a closed hood, they are your best option as the GU10's are 240 volt and not designed to go into a sealed/enclosed hood.

[wayne g]

i must admit that was my way of thinking also mate.
what do you reckon...will the double be enough or shall i go for the tripples?
damn....i can remember thinking that way about halides not so long ago!

[jaggybunnet]

Guys

This is what I use they are waterproof 150 leds sealed in a plastic strip:

What about these, they are similar fitting to a GU10, but 12v, same wattage and LED's as the 240V version. You won't get a shock from them, but ultimately salt will get into the same places as it would with the other. HOWEVER, since they are LED and shouldn't need replacing for a very long time why not use some heatshrink, preferably use the stuff which has heat activated glue on the inside, that should make it nice and snug, (Jas - thats what I used on those probes a while back)

An after thought, you could just solder the wires directly to the terminals on the back of the lamp and insulate them using heatshrink. Not sure if you would have any problem mounting them then tho it would be simple enough to make a bracket out of a bit of acrylic.

question answered......i bought the triples and jeez.....they are mental!


my camera is pants and the battery was nearly dead...this only gives a glimpse of what 45 waterproof leds do to a 20 gal nano...












.....again...i can only repeat that the photos just dont show how much flourescence i am now getting!

[ben]

from the photos i can guess what its like. lit up like christmas

[wayne g]

it is mate....
if i saw an accurate high quality DSLR photo of it on a forum i would assume photoshop!

21 quid all in as well!

If you are looking for some of these bulbs, give me a shout, as I can get them a fair bit cheaper than £10 + Vat
