I bought three couples of LED lights from IKEA, they come in packs of four. Each pack has a box that you connect all four lights to called an "electronic LED converter". Now, I want to have 6 lights in one corner of the room and instead of having two converter boxes there I was wondering if it's possible to just rewire it so that all 6 lights go to one box?

The box has this text on it if it helps:
SLT6-12VLS
Electronic LED converter
Prim: 220240VAC, 50/60Hz,0.07A
Sec: DC12V, max.500mA, 0.5-6W
DC700mA, max.8.5V


And here's the link to the product if that helps:
INREDA LED spotlight - IKEA

Will 6 lights be too much for the box meant for 4 lights is what I'm wondering?

 

I only see 4 outputs on the connection. Also most times kits like that are only sized the the loads included and do not leave room for expansion.

 

That's what it says on the site but gives no information how to do it or how much wattage each unit is.

You may have to check directly with Ikea.
