I am a bit confused here for I see a lot of lighting topics lately, but I am so noob I'm not sure what PC, MH,T-5's, and halides lights are or what they stand for. What is considered "strong lighting"? What is good lighting?
Strong Lighting?
- Thread starter MarineDream
- Start date
NO - Normal output flourecent
HO - Hight output flourecent
VHO - Very high output flourecent
PC - Power Compact flourecent
T5/T5-HO - T5 flourecent
MH - Metal halide
Different corals mean different lights, MH and T5 are most popular in reefs, PC's are also popular.

PC or Power Compacts seem to be the norm in what people buy.. the cost is just right and the quility and the way it burns is just great. Everything else rotates around the PC. T-5'5 and T-8's are up and coming and seem to be popular with the DIY people or just rebels. they do burn hotter than the PC and you have to run multiple bulbs to get teh same wattage but people say its cheaper. Then you have the MH or MEtal Halides. These are by far the Hottest burning and eat the most wattage, but they give you the essential wattage andbrightness required for corals and some plants. This type of ligting is made for the hardcore enthusist. ushually you can contact your LFS and tell them the tank you have and what you plan to have in there.. then they can help you match up with the corect lighting system
DAYLIGHT= type of lighting color COMPACT=the bulb type
technically daylight is any type of white light used to view fishes.. and anytime you see conpact in it it refers to PC.

Lighting is definitely an issue that we should know more about... I am one of those people that have been asking questions and asking for recomendations.
I can tell you that everything I've read so far has been acurate to my knowledge... I would add a couple details though
A T-5 bulb refers to the size, or guage or the bulb ...
I.E. a T-5 bulb has a smaller diameter than a T-8 and a T-8 is smaller that a T-12
A N.O. (Normal output) bulb is a florescent that takes aprox 30-40 watts to run and they put out the least amount of light aside from incadesent light (house lights etc) which doesnt put out any benificial light
A High Output HO (Normally a T-5 HO) takes aprox 50-60watts and gives off a stronger light...
A VHO (Very High Output) takes aprox 100-120 watts and puts out a wide range of color spectrum with light that can penatrate deeper than any of the other florescents.
PC or Powercompact lighting seems to be more like the H.O. T-5's however the seem to be a little more efficient and seem to penitrate the water a little less.
MH or Metal Halides are a very strong light that penitrates deeper than any of the other forms or bulbs... though they put out the same amount of heat as the other bulbs they can easily overheat your water or even burn surrounding due to the fact that the heat is concentrated into a much smaller area...
MH seems to be the best lighting available to reef tanks especially deeper tanks...
The term actinics or daylights refer to the color spectrum that the lights emit.
Actinic put of a blue-purple light that mocks the light in deeper water it is usually dimmer than daylights and does not penitrate as far. Actinics are great lights to simulate the day-night cycle and are best used early in the day and then again at before dusk. most people myself included used these all day long because it is easier and cheaper to use on timers... the simply come on before the daylights and go off after the daylights...
there is another type of light that is being used know as LED's or Light Emiting Diodes... these are generaly small lights that are used to simulate moon light and help spawning and other night marine life...
I know that there are other types of lighting like mercury lights etc. but someone else will have to talk about those simply because I have no knowledge of how they work or their other specifics...
I hope this helps anyone who may have lighting questions...

That would depend on species, size of tank placement in said tank and how far away the bulbs are from the water surface, knowing the type of lighting would be really helpfull also you would need more wattage from a t-5 than a halide depending on placement.
My current lighting for my 29gal Oceanic:Biocube;
1 - 36 watt True Actinic 03 Blue Straight Pin.
1 - 36 watt 10,000K Daylight Straight Pin.
3- .75 watt Lunar Blue-Moon-Glow LED
The LFS has one of the same tank set up as I do and they have a few coral/bubble anemones in them. Either I can get away with it or they changed their lighting (maybe I should ask) but im always trying to double check
