I would like to see PAR output levels at different distances, ie. at 1 foot, at 2. foot and at say 3 foot (just for thepeople with the realy deep tanks) as well as with the type of bulb, age of bulb, and type and age of ballast.
when they say "The current design produces PAR light output levels equal to a 250W MH 20K. " well what brand 20K, what brand ballast, .. I can put togeather a 20K set up that will give you less PAR than a 10000K PC set up, so it is a very easy bit of advertising to manipulate.
as far as the energy savings.. I thik that realy sucks when you think about it.. only 40% better than a 250 MH set up.. so lets see that would save me about 36 bucks a year. I am looking at a 36" modle for my tank at about 1900 bucks US so Island price will probably be about 3K after shipping, tax, exchange, ect.. so I have a complet set up for 500.00 with bulb changes every 18 months, thats about 600 bucks over 10 years in bulb changes. now power is about 15 bucks a month for my lights if that but I will be generous so that will come to 1800.00 for a grand total of 2900.00 for 10 years.
lets look at the LED, to start we are about 3K to buy.. we will say there are no faulty bulbs and they all last 10 years (good luck.. I will say you are probably going to have to replace 10% befor that and they will be expensive but we can't guess on that right now) power is 40% less than MH so if I got 1800 for power on my MH that means I should be about 1080.00 for power for 10 years on the LEDs. so with out bulb changes we are at 4080.00 hmm a grand more..
