Hello can you tell me if a 150watt light bulb 240v will be ok for the Sonoff Basic
i have 15 watts led panel light total 15 pcs ....can it be connected in single sonooff basic .....or required 15 pcs each ...trhanks
150VA / 240V = 0.625A The basic is rated at 10A so yes, it will handle it easily.
"15 watts led panel light total 15 pcs"
15W * 15 = 225W or 225VA
For 120V circuit: 225VA / 120V = 1.875A
For 240V circuit: 225VA / 240V = 0.938A
The Sonoff basic is rated at 10A into a resistive load. If you are pulling a heavily inductive load like a LED or CFL transformers or ballasts I would derate it by 30% to get the expected life out of the relay contacts. For that type load 7A or less should be okay.

Then you have an inductive load of 225VA. Divide 225 by your voltage to get amperage.
For inductive loads I would probably try to stay below 7 amps. Inductive loads put more strain on the relay contacts.
15 x 15W = 225VA / Voltage = Amperage. So if your line voltage is 120 the 15 lights require a total of 1.875 Amps.
For an inductive load like LED transformers I would keep the Sonoff basic load under 7A to protect the relay contacts.
