IR Floodlight

[Lightspeed]

Yes the vents could be closed off using tape. I need to see how hot this little device gets before doing so though as It will be left powered on for long periods without me being around to watch over it. It mist ne totally fire proof.

Range is good for around 45 ft with my cameras. Range will very much depend on the camera's sensitivity.

Spot lights: Yes it could work, but I'm not able to find time for experimenting at the moment as IR spot lights are not a high priority for me. I get where you are coming from tough and it might be interesting. What about something like this: http://www.ebay.com/itm/808nm-Focusable-...1297714760 Its is a variable focus device so by de-focussing it, you'll end up with a broader beam.....a bit expensive to play with in testing though?
