We are considering putting lighting in some large trees (40'tall and 60'
width) in our yard. We live in Tulsa, OK if that matters. I am working
on putting in an irrigation system and while the ditches are there,
might as well put in some power to the trees for lighting.
I prefer to not mess with the low voltage lighting and transformer -
prefer to just use the 110v comming straight from the house (using 12/2
UF cable). I am not opposed to using a trasformer, but it will be
easier for me to just use 110v.
Can anyone recommend outdoor lighting for the trees - would like some to
be pointed up and some pointed down to the ground.
110 is the way to go...if you went 12vdc you need heavy wire
to get the lummens you need, and those tend to corrode and
components are not common.
Heat is a problem though with incandescents, but that gives
the best broad spectrum light, showing up color well and
healthy for the tree.
Maybe warm *full spectrum..fluorescent flood bulbs would work,
they max out at 100w though. if you dont like them you can
screw regular incandenscent outdoor floods or spot bulbs
in...you can run 14/2 to the individual lights...that will
carry 9 amps steady. (1000 watts at 120v)
You will probably want some 200 to 600 watt spots to light the
top of the tree. you could easily have 1000 watts on that
thing...thats 9 amps... 12/2 would be fine. Myself I would
pull at least 10/2 in case I wanted more light... the 12/2
maxes out at 15 amps (steady) 20 is just the max limit.
There are 10,000 things to consider...
-Shape of tree - wide Oak or tall pine or...
-Distance from ground to first branch
-Density of branches/leafs (and evergreen or deciduous)
-Use of the ground under the trees - play lawn or plantings or...
-Brightness of surrounding lighting - dark forest or city streetlights
-How long will they be lit - a few hours during parties or all night
every night - $$$
Fluorescent floods are effiecient but limited to short and wide
Metal Halide are better for big bright fixtures.
Incandescent (halogen) are best for small focused uses and for small
fixtures up in the trees. I've used lots of MR16 lamps (12V) in large
and medium trees. Leave the transformer on the ground and you have
great mounting options.
But first and foremost get some local experienced help! You describe a
big project and your going to waste far more than a consultant will
cost without some specific knowledge.
