Neptune Aquatics

Gimmito's 450 gal L-shaped tank

Gen's been working on the light rack design. I'm still contemplating using an actuator or a pulley system. Any thoughts ?

A simple pulley system should do well for you. Its behind the scenes so its not as important to look really nice. However, you have gone all out for this system so why not do the actuator as well. haha.
 
Some thoughts:
I think it comes down to access requirements.
Do you need to raise the lights from the display room, or really just from the garage side?
If from the display side, you probably do need an actuator, because you likely only want a nice clean switch, not
some ugly rope hanging out.
If from the garage side, while cool, seems like a waste of money, and yet more things to fail / corrode.
It would be in a possible high heat + high humidity location.
I like to watch them feed, so I would guess display side, but up to you.

Another note regarding the connection after looking at the drawing:
You probably want to run 4 lines, one from each corner of the light, up through pulleys.
Then, connect those together after the pulley, to one line, which then goes through your blocks/actuator.
The upside-down Y connection takes vertical space, so you cannot raise it as high, plus it can swing around a lot more.

Unclear from the drawing, but if not already thought of: you will want several parts on your block if you do it by hand. Probably 4.

You're making hard to not go w/the actuator. I'll have to pick Ed's (DrDooLittle) what else I need to put one together.

Mark...thanks for the advice, it must be the engineer in you. ;)

I just picked up a Maristar 4 foot 2x250 w/halide/t5 combo from H20player. I just need a hanging kit and I'm good to go. :bigsmile:
