The price for one CBX3590 with 3500k is 112 USD ) dimmable.

Two pcs are 205 USD.

When i build by my own i would pay maybe few usd less. what do you think?

Yes also have talked with them yesterday, the price from them is higher then the first one.

I need single moduls for now.

So maybe just take a longer cable for the power supply.
