Get it online and ship over. Ask some contractor install for you.

Probably only cost you RM1.5k

Rm1.5k is equivalent to the cost of electricity of a 10w LED bulb switched on nonstop for 43 years @ average rate of 40sen/kWh.
Or the yearly interest earned from RM1.5k FD placement is enough to cover the electricity cost to light up a 10w LED bulb non stop for 1 year + a new replacement LED bulb every year.

Just a view strictly from costing perspective  tongue.gif

Hmm... True also.

TS, you read it. Forget that skylight.
