Going from Metal Halides to LEDs...

[LHB]

Hello all - I just upgraded my (very old) MH fixtures with two AI Hydra 32 leds. I previously had 2x250w 14k halides and 2x39w T5 actinics over my 70g tank. Electricity bill was killing me and these LEDs are obviously way more efficient. Does anyone have any advice as to how intense this lighting will be for my mixed tank (mostly SPS/LPS)? I know it will likely be lower PAR, but do I have anything to worry about? Just crank them high and keep an eye on things? Should I repurpose my 2x39w T5 bulps with some 14k bulbs to add more PAR?

A par meter will be very helpful in this case,
Two hydra 32 over a 70 gallon tank can put out enough light for even the most light demanding coral. Also they can burn lps if not dial in properly.
