I am currently converting my 20g long planted tank into a saltwater aquarium. I am running a 2 x 31 watt t5 bulbs. One is 10,000k and the other is a Actinic. Would this be sufficient lighting to maintain sps corals since a 20 long is more shallow than a 20 tall? or would I have to upgrade my lighting fixture?

i am replacing two light bulbs in the garage with two tube light fixtures…. currently both lights are controlled by one switch. I want to have a seperate swith for each of the tube lights. I have a picture drawn on how the wires are connected right now…both at the switch and at one of the light bulbs. I can send the diagram as needed.

I’d like to wire LED lighting to put under a lip at the top of my new retaining wall. A lot of the actual landscape light fixtures I’ve found are big/fancy/expensive. I’d like to wire something that will be solar powered and have the effect of strip lights–either by buying inexpensive waterproof LED strips and connecting them to solar power, or by going one step deeper and wiring individual LEDs to suit along the edge. I’ve found dealextreme.com for some parts, but does anyone know of a good resource for instructions on assembling this type of thing?

I have a light that won’t fit if I use the existing bracket. Is it bad to mount the fixture downwards instead?

I have just been licensed in california to grow for ailments and am curious which lighting fixtures maybe the best

We have many light fixtures in our home and business that have dimmer switches on them. We are trying to save energy by installing CFL lamps but most of the bulbs say not for use with dimmer sockets.

Is this because there is some hazard with using them that way or does it mean that they won’t work or that the dimming feature will not function?

Thanks for any knowledgeable advice.

My girlfriend bought a motion light fixture and It’s not the normal U.S. 2 wire fixture. Do I need to install a 3 way switch for this fixture?
The house only has single black and white wires, no red, green, yellow.

Usually yellow is hot and green is ground but what is this wire?
It’s 25 years old. So taping it off should be alright?
Alright I got it working now I gotta figure out how to set the timer and all the other crap,lol. Thanks

We are having trouble finding this item is there a web-site to go on? It is a block that goes between the light fixture and the vinyl siding.

florecense light.
the light is above the sink.
can I get rid of it all together and replace it with a regular light?
thanks.
