Talking pics of my redone canopy (switch to ODNO)

all i can say is "wow! thats bright!"

hello all, this is my first post. :P

i recently built my own canopy and my own light using 2 5000k philips daylight bulbs and 2 18" All Glass aquarium bulbs (came with my 55)...
well, i still wasnt getting enough light.. so i decided to grab 2 Advance 4-F32T8 ballasts and went to town.

this used to be a standard Lithonia Lighting 2 bulb T8 fixture.. till i added more bulbs. (i cant stand wasted space)

here are the results:



i like to keep my wires neat.

here it is all lit up.
everything thats even remotely colorful in my room here is just glowing. i cant wait to see what it looks like on the tank.



ive got it sitting on the bench running right now to see what kind of temps everything gets to.. etc.
if i measure conservatively and estimate that every bulb is running at 170% of normal output capacity for these ballasts, that puts me at 217.6 watts.. or 3.956363636363....WPG.

the bulbs have been changed to:
2 - Sylvania Daylight Deluxe 6500k T12
1 - Philips Daylight 5000k T8
1 - URI Aquasun T12

Welcome to the Planted Tank!

Looks like an excellent job to me. I like how you took the switch/plug out of the computer powersupply, good idea.

ty.
i didnt want a cord hanging from the canopy if i ever had to remove it.. so it seemed like a natural thing to do. the rocker switch was a "hey i wonder if this will work" idea. :P

they are just slid into the holes with the wires soldered on.. then i backfilled the hole with silicone.. so the switch and plug are permanently mounted to the canopy, but they are waterproof and i have enough wire there to do anything i might want to do in the future without having to worry about rewiring.

I think the only thing I would have done different is to not have the wires so close to the bulbs(.. they may touch and melt the insulation a little over time...(I dont think it be that much trouble to drill a couple of holes and hide them under the metal... imo) just make sure the connectors NEVER get wet either... by condensation or other means.. and that they are EXACTLY square with the bulbs.. these bulbs get hot and expand things (like the sheet metal etc)... I had one of my bulbs arc and blow out my balast! just a warning. You may want to invest in or make your own water resistant endcaps.

I was also wondering about the excess heat that would get built up in there. Is it getting pretty warm in the canopy? Might not be a bad idea to wire in some small little PC fans into the canopy to help remove some of the heat that those ODNO's are going to produce.

Also might not be a bad idea if a moderator moved this to the DIY forum or the lighting forum..

i actually have plenty of clearance between the wires and the bulbs.

the PC fans are the next thing. there isnt a huge amount of heat buildup under the canopy.. but i will be adding fans as soon as i can get my hands on a hole saw. :P

also. there is a glass cover that goes under the light to keep things dry that you havent seen, and a lens i can use if i really want to get paranoid. :P lol

i built the actual enclosure from a 2x8 foot sheet of MDF i had in the garage. (and had a piece that was 2'x47" left over) - $0

The light was a normal 2 bulb fixture from home depot that came with a 2-F32T8 electronic ballast (that i got for free from a friend that owns an electric company) - $0

2 4-F32T8 Advance Electronic ballasts from the same friend - $0

4 locking medium bipin terminals - $0

it also has a small rocker switch and a modular plug adaptor in the back that came from an old computer power supply i had. - $0

4 12v fans from same source - $0

i used some paint i found in the garage. my luck, i had white and black. :P -$0

2 Sylvania Daylight Deluxe 40w T12s - $8 pr at Lowes
1 Philips Daylight 5000k T8 - $5 pr Home Depot
1 URI Aquasun 40w T12 - $24 LFS
2 24" MarineLand glass covers - $18 ea Petsmart



I like that i added a modular plug because i dont have a cord dangling from it if i need to remove it, i can use any length of modular appliance cord which is readily available, and its neat. :P

4-F32T8 ballasts like the Advance, or Workhorse5, etc. generally run for $20-$30 at most lighting supply stores or Lowe's / Home Depot, if you can find them there.
