Which is better for the living room light 7W or 12W

This drive generally has a false standard, and it is better to be larger. The 12W driver drives 12WLED, and the power is only about 10W. You still buy 8-15W more scientifically. It's not good if it's too big, and the light decay is great.

You can directly change the 220V integrated LED spotlight, the 3W brightness of the LED is equivalent to the brightness of the halogen lamp 20W, and the 220V voltage can be directly connected to remove the original driver. Recommend the three brands of MEGAMAN, Osram and Philips. Domestic NVC lighting and Opple lighting can also be used. >>>More

LED wattage is small, brightness, more durable than the traditional one, relatively long life, you choose one headlight or two in the living room and dining room, and whether you want to install downlights or what. If it is a whole, then install a large lamp, a 3W small lamp, and the general light source is about 20. A dozen watts of kitchen and bathroom will do. >>>More

The resistor-capacitance step-down circuit in the figure is more dangerous because there is no isolation, it is generally suitable for low-power wicks or charging batteries, the size of the device on the circuit board in the figure is difficult to see the load 3W, it is recommended to consider the mobile phone charger plus LED driver plus LED scheme.

Depending on how big your living room is, and the density of the light source, if it is very concentrated 108W LED brightness is very high, I don't think it's appropriate, if it's scattered, it may be better.
