where to get epileds dual core 410-420nm 1300ma?

can't find these anywhere that's the same in the picture thanks!

If you can't find the Epileds, these Epistar may be an alternative for you:

You can just run this chip if you want. The extra 2 chips aren't going to put any undue strain on the drivers or the power supply. The 180w pucks run on the same power supply as your older pucks anyway.

thanks i was looking at these earlier but it says 700ma max? when the maxspect versions are 1300ma? what's forward voltage?

SkullV · 02/27/2016, 10:44 AM

Maxspect lists their UV chip at 1300mA? Probably why they burn out so consistently. Like I said before, Nearly any UV chip commonly used in the aquarium industry that you put in there is going to burn out. They just are not meant to run at the same current as the other chips in the string.

johnfallon135 · 02/27/2016, 12:05 PM

i see. could you tell me what forward voltage is? i see it for all the leds usually at 3.4 - 3.6 volts. my maxspect runs at 34volts so what does this all mean? thanks!

13.5v @ 700mA (~3.4v/chip).

yeah i understood that but i meant what does 3.4v/chip mean?

It means that the quad core chip has 4 chips running at ~3.4v @ 700ma. It's the same as running 4 other UV chips in series.

Forward voltage is the voltage required to turn the LED on.

An LED needs a voltage to turn on and a current flow for producing light.

so it means as long as my plug is 3.4v or higher it will work right? or does my plug have to be the same power rating?

Your plug is likely the same rating or very close. If you're 34v reading is at the power supply you are taking it before it is split up to the smaller LED drivers on the internal controller board. If you are asking whether you can run a chip rated at 3.4v in that fixture, the answer is yes.

what if i use a 3.6 volt chip does it matter?

After 4 years running my razor at 100 percent why are my 410/420 chips still working?

oreo57 · 02/28/2016, 06:58 PM

finding those chips in the "wild" is going to be tough..
An interesting link, and in need of translating..

However , 410-420nm element is a dual chip of special shape of the example , because there is only mounting pattern 2 months worth also to the substrate , it is virtually impossible to increase the UV -based element any more . Also , seemingly remove the Cree XP -based , but it seems like can I put the UV element of compatible shapes such as SiBDI S35-U and SemiLEDs C35-U, up to 700mA of these maximum rating is 3W. On the other hand , since the design Razor is flowing up to 1300mA per element , you can not use at all . . .

Forced or put try the UV element of 5W of LedEngin?

"stuff" everywhere..

johnfallon135 Hello, please tell me how you solved the problem by replacing (Epileds Dual-Core 1300mA)
where did you buy? happened to change?
