LED Lighting Spectrums - help please

[suztor]

All righty, I'm actually a little suprised that I haven't found any articles/ threads on using LED lighting since it's supposed to run cooler and last longer.

I have flourecent lights but they give off lots of heat and that just doesn't work for me. I'm looking into making my own LED lights (if the price doesn't go over what I can buy pre-built)

The BF is going to be helping me get all the wattage and all that sorted out (he studied electrical engineering and is handy with electronics and such)

What I'm having a hard time finding is for freshwater med to low light plants (the tank will be somewhat planted) what part of the color spectrum do I need to cover? and how do I find this information on LEDs?
I've been googling for two days on this and I'm having a hard time finding a straight answer. i. e.
Plants need ________to______ Spectrum
White LED made by ________ emits ________to ________ in the color spectrum
Red LED made by ________ emits ________to ________ in the color spectrum
Blue LED made by ________ emits ________to ________ in the color spectrum


also correct me if I'm wrong but I've read that Red spectrum is needed for flowering plants and Blue is needed for growing green plants.

when using White LEDs should I include other colors to fill in gaps in its spread and which colors should /would i need to use to do that.

Also I think I'm going to have a day and night setting which should be lots of fun to see

As for housing I will either use half a black PVC pipe or disassemble and paint an existing light fixture I don't like.

There are quite a few threads on here about LED lighting. You will need to adjust your search criteria.

I use a combination of LED and standard florescent. I was forced to do this as affordable LEDs that support plant growth do not exist. If plan on using full shade plants and mosses for terrestrial enclosures, you can get away with it, but growth is not optimal. For aquatics, it is best to stick with fluorescent in my opinion.


When it comes to LED "colors" be very very careful. What the actually emit and what you see are often two very different things. Also remember that light is not paint. To create "white" light you need the three standard primary colors and green. Even then, this is not true white light.

As for green, there currently no consumer grade true green LEDs available, just shades of blue that look green to the human eye. With white, true white LEDs are very, very expensive and last no longer than a flourescent. Most "white" LEDs are actually shades of blue or yellow. The few available that are true white either lack the intensity to support plants, or consume so much power and generate so much heat that fluorescent are a superior choice.

Since heat is an issue for you, LEDs are definitely not a superior option as consumer grade LEDs and their support electronics generate comparable heat to standard aquarium florescent when used in amounts that barely support plant growth.
