Lunar Link power supply?

The package says Ideal for use in all Freshwater, Saltwater and Reef Tanks. Also great for terrarium use.

I tried a variable power supply from work, and at 12VAC it works great. Maybe higher would work, but 12V is the usual rating for the ultrabright leds... I found an old adaptor at home that was rated at 12VAC and the plug fit, and it works great. Very bright thogh for a small aquarium. I'm planning on installing the light tonight, to see how it looks, but I have a feeling I'll be adjusting it to dim the leds a bit... Now to get to work on building a 2way timer to automatically switch between the daytime and nighttime lights...

buddy, it might work like that, but LEDs are usually rated at around 3.6VDC

then resistors are either included, or built in to allow a 12VDC current to make them light up.



Go out, get a 12VDC adapter, plug it in..... its pretty much guaranteed that it will light up....

darksoul, you're right, it should be 12VDC. I wasn't paying attention... Also, regular LEDs are 3.6VDC, but any ultrabrights I've picked up were 12VDC

12V standard? I havent dealt too much with LEDs, But ive purchased some ultrabrights that are 3.6V by default, and will only use 12V (or whatever else, really) with the proper resistor.... i found out the hard way that connecting those to 12V was a mistake they were ULTRA bright for a fraction of a second though lol

I have also seen some that build the resistor right into the LED somehow, so it is still actually 3.6V, but because the resistor is built in, it becomes 12V .... and to be honest, I dont know how to tell if they have the resistor built in or not.... usually just go with whatever voltage is listed.

all of that aside, yes his lunar link is probably 12V, its the most logical option.

this whole lighting system though makes no real sense to me tbh .... i dont understand the product, and why having the ability to link another 2 LEDs to it is any better than just having 2 models with varying amounts of LEDs.
