end views of wing type reflector with ruler please?

[bobhamm]

I know the feeling, yeah if there was a place anywhere near here I;d go get a pic in person, till then I will depend on the kindness of strangers

bump bump bump.... hopefully now that I have clarified what I need someone can help? making a DIY cooltube today and a reflector would be a nice addition once the temps come down from adding the tube

for my cool tube i built a reflector from an 8" expanded air duct. the type you fit together yourself to make the pipe. i just spread it out to about 22" with 2 steel dowels to keep the metal arched. it's not perfect, but i can put 1000w 8-10" from the tops of my plants in a 4'x4' closet and cover em all.

whats the diameter of your cooltube? yeah I figured Id probably do something like that since no one has a picture of a wing reflector
so obviously no hot spots from your duct reflector?

 

[iampolluted]

nope, no hot spots, and never a burn on the plants. it's a 6" cool tube about 19" long. it's ghetto but it works until i can figure out something better.

 

[bobhamm]

yeah I know what you mean mine looks like some 5 year old was given some shiny tape and went to town on it but it did drop temps 10 degrees so... how is yours attached? how far above the tube? I'm wondering if I can just lay my duct right on top of the tube

can't u go to a local hydro shop and look that the wing with ur own eye i bet they will even let u measure it too in the store
most guys in these shops r good ppl just don't tell them ur mocking it for a diy

good luck

This is what you should aim for. By not having flat piece with a bend the hot spots are greatly reduced, if not eliminated. And because the contour is round you can manipulate it so the light can be either spread out more or concentrated. One place I worked in BC we made shades of all sorts of shapes and sizes and eliminating hot spots is alot of trial and error.

Well, I'm not sure I'd agree with you as to the flat sides causing hot spots, found a great thread at another forum where they tested light patterns from diff reflectors, the super sun 2 came out on top, and from what I can see from the pics in ads its just a 4 flat sided(plus 2 ends) refelctor, diffuses the light nicely. I may just go with attempting one of those. I did attempt bending a curved piece and had no end of hot spots

i just drilled 2 holes in the duct and slid the eye hole screws from the tube through it and laid the duct on top of the tube.
