An Instructable to help lengthen the distance of your Infrared lamps
Step 1: The Truth Is Out There
Not having a huge budget we decided to use infrared lighting and modified digital cameras for many of our investigations - however what folks don't tell ya is the infrared is not really focused like a normal torch beam due to it being a light not visible to the human eye - so the shiny mirror reflector on an infrared light does not do that much.
Step 2: It's Vanished!!
Our lights tend to be about 2.5 inches across - I was wondering if a white reflector could give a bit more range.
The only tools needed here are few.
Some meaty scissors.
Hot glue - solid but not permanent, just in case the result was poor.
The white version of Vanish washing powder.
Empty out the contents - cut off the threaded end - cut a hole to go snugly over your light - hot glue into place.
Step 3: The Result
The one shot is being lit by a standard light bulb set into the ceiling - the other shot is with a modified camera using the a single light with reflector fitted - I am even tempted to fit a variable resistor to turn down the illumination as here the light is almost too bright.
Step 4: To Conclude
Tried this mod on a linear array and it seemed to make little difference (range was good already but did not get any longer ?), not sure why - give it a go, if it helps ya out then all good.
