jeanie !
fantastic little mod there !
just a little word or warning on those Harbor Freight lights.
u get what you pay for.
I used several back in the day in 3 ponds.
I thought.. "wow !!! 10 bucks !! can't beat it !"
they push out the light fine... but then... the trouble starts !
the intensity starts to wane..... the plastic lens cover becomes discolored and warped... lights leak... corrosion on bulb and pins.... BLAP !
Lights worked for maybe 8-9months...then nothing. Don't feel like replacing lights yearly....
good luck
