The only way to 'fool' an infra-red device is to line your grow area with LEAD DRYWALL...like the offices are where your doctor takes xrays.

That is the ONLY way to conceal the heat from lights.

And your simple possession and use of 1,000WATT HID bulb is not by itself illegal. ..nor is it "probable cause".

At least not in the states.

And as stated by RacerX, the CFL's aren't going to even show up on an IRD.
