Yes, but bear in mind that's absolute maximum for the entire track, half the track would only be rated at 0.5W, and so on. However, I would suggest running it at far less power!, I notice the spec advises using a high input impedance amplifer as a buffer!.

Thanks Nigel, I will be using a lot less power then that.

I dont know what a high input impedance amplifer as a buffer is, but I will use the senor as a voltage divider hooked up to a LM3914 LED driver chip. The Led driver will then switch on stuff. Click to expand... That's fine!.
