Re: [APD] Aquatic-Plants Digest, Vol 45, Issue 21

Led lights produce about the same heat as a CF ballast, they also require
additional circuitry to convert AC to a low voltage DC which will generate
heat of its own.
There have been advances in LED spectrum's and you can buy LED plant lights
but the cost is prohibitive unless you have money to burn and they don't
work as well as MH or even CF in the long run, and they don't seem to last
as long as CF but they do last longer than MH, but a price of over 400$ per
bulb that only is equal to a 75W MH just isn't worth it IMO.
