I think that is a little misunderstanding. I'm sorry-I don't know Italian :(

I can make the lamp from 40cm up to 120cm long, 120cm is the limit, because this is maximum lenght of one single piece of aluminum heatsink.

LED modules dimensions are 25mm x 155mm. Each one module contains 6 LED bulbs which gives approximately 20 W / module.

For example - If you want the lamp 80cm long with 320W of power, -first we need to check if the aluminum heatsink will fits 16 modules (16 x ca20W = 320W)
