Prices are creeping uo (in the near future maybe jumping) and it will be important to check running costs as well as adequacy of lighting. I think the majority of reef aquarists who need high intensity lighting continue to use metal halides. The balance of choice could well swing towards Led's if their initial costs reduce and I understand they are likely to do so. Things continue to develop. With regard to heating, on my reef I have a bank of five fluorescents (T8's would you believe) and when they are on it's clear that heating costs reduce - there is a 'blinking' exterrnal heating controller and the 'blink' reduces or goes off completely. The only thing then is to ensure the heat doesn't rise too much! Thanks for that – very interesting about electricity costs ‘nuclear and non-nuclear’.

In France , we pay 0.07€ ( 0.1$) each kWh ( because of nuclear energy !) including taxes : 0.09€ /kWh = 0.128$/kWh So using a 250W MH bulb costs us 9,6$/month (10 hours a day) In Germany they pay twice our prices ...( because few nuclear energy ) So in France we are mainly used to use MH ( RX7S) , (added with 2xT5 ctinic ) but many reefkeeper prefer MH bulbs 20,000 K from 250W to 400W , although it cost a lot in energy consuming .

About heat : we can also admit that heating a 100 Gallons is expensive . Using a MH reduces heating the tank . It's better to heat while lighting than heating out of lighting ...

It was written in September 2007 so, although the principles remain correct, LED's could well have advanced considerably. Also there may be more LED lighting units available to aquarists at a lower cost. Glad you liked the post.

Yes, the argument continues. I am quite happy to accept that LED's are still developing but they have advanced a long way. Cost seems to remain one of the downsides but open market competition should be having an effect by now. Depth of aquarium is another consideration. MH is still the major reef aquarium lighting used but for how long I wonder, with the downsides that are inherrent in the system, such as running cost, heat and relatively short bulb life. There are lots of articles and opinions on the internet which are easily found. I've listed some articles which could be of interest particularly the first. Specific equipment is mentioned but it doesn't really matter. http://www.advancedaquarist.com/2010/2/aafeature2 http://www.advancedaquarist.com/2010/5/aafeature2 http://www.advancedaquarist.com/2010/5/aafeature Hi Matt.
