Lighting source - pt. 2 DIY reflector hood.

The first part of the grow was started with a CFL bulb in a clip on light hood.  These are under $7 at Wal Mart and it is handy to have a couple around the house.  For the second part of the grow a 10W 6700K CFL bulb for a coral reef nano aquarium is being used.  It is longer than your typical CFL spaghetti bulb and thus a different style of hood is needed.  A proper hood was made from a piece of 12" x  24" aluminum picked up from Lowes.



A template was drawn up in TurboCAD and then transferred to the aluminum sheet. 



Used some tin snips to cut the aluminum.  Bent the metal up and pop riveted it together.  One of the original lamp hoods was used for it clamping brackets.  Drilled a hole and threaded the lamp base on.  Fit like a glove.  This is what it looks like from the bottom.



If I were to do it all over again I would make it 1.5-2" shorter.  All in all it did not come out bad and will be effective.
