I would like to findout what is the difference btw MH with 6.5KK, 10KK, 15KK and 20KK.
Is it because difference in the light intensity? If that is the case, as most reefer using 10KK, is it the most recommended for?
Comparison:
I know PL/T5/T8 generate less heat compare to MH, but example, for a 4x2x2ft tank, we may need 4 pair of T5 to have the tank covered compare to properbly 2x150MH light, the price will be a great difference. 4xT5 would properbly cost $800, whereas a 2x150MH would cost $400...no brand quoted.
Would the expert reefer advice is to choose T5 or MH even w/o the above comparison in price?
I am in a stage of lost to which light should I choose to put up SPS & LPS...this would be the cost to have number of lights, running cost (Electric fee), maintenance cost (bulk change).
Any expert reefer pls give me some advice.
