Hi all,
Doing renovation at unmarked house. My wife suggest to use PLC lights at my L-Box for my living room. 2 at each side which make it total of 8 PLC lighting. My living room is small though.
Questions is wat is the total watt required for each lighting part.
Will 2x13 watt be sufficient or 2x18 watts will be bright satisfactory?
or should i stay with 1x18 watt? i'm using white lamp and i need the living room to be bright satisfactory for gatherings. i also place a chandelier contained by the middle just to create ambience atmosphere
What can impose condensation to build up surrounded...
Answers:    I'm an electrical estimator and I hold no idea what a PLC muted is nor do I know what the hell and L-Box is. Try again.
