Actually, the LEDs should be more efficient. They convert more energy into light than heat compared to MH. They will use less power than a comparable MH set up and transfer little to no heat to the tank so you're less likely to need a chiller. Also, as long as you manage the heat around the LEDs themselves, they will last for 50,000+ hours so that's a big cost savings in bulb changes too.
Also, you can control the blue and white LEDs separately to fine tune your colour temperature to exactly what you want.
