Hi Guys, So I'm designing my own home lighting. Having problem looking for 0-10VDC LED Dimmer switch. Basically my design goes like this. 0-10VDC Dimmer switch >> Power Supply with PWM output which allows dimming >> LED Strip Power supply will have its own VAC power input, and also analog 0-10VDC input as dimming function.

Hi Guys, Is this a potential water seepage? The mark appears on the ceiling of master bedroom toilet. Please advise.

Hi Guys, Just wondering is there any store where I can get things like faucet etc for a good price? Something like CCM for electrical parts? Is there an equivalent store for plumbing? Thanks

Hi Guys, Was changing the power socket and light switches for my place. Everything went well, except when I was disassembling one of the light switches, I realized they are all the same color (too late, cos I have removed the connections, wrong move I know) Moving forward, how can I be sure which wire is Live, Neutral, Ground. My apartment color coding goes this way for other socket (L-Yellow, N-Black, G-Green) Whereas for light switches, they are all using yellow color wire. Please suggest if you have any idea as this is the first time I encounter such problem.
