I use HID's, LEDs, Fluorescent, and Sunlight.
People saying one is better than the other don't understand that they all have their uses. For some applications fluorescents work better than HID or LED such as starting plants from seed. Claiming one light tech is better than another light tech is not really looking at all the various scenarios. It's actually cheaper to run an HID in some colder climates because you won't need to run a heater and if you do for much less time. In that scenario you may be saving electricity by running HID lighting. In fact there have been posts on this forum where that was the case. So the argument about cutting electricity costs in half is not true for many. If you have to add heat then you're not saving any power.
Many people have only grown with one type of light so they're going to try and claim that it's the best option out there even when it may not be. Many people using LEDs have never grown using HID's so the information they have pertaining to the quality of the bud that can be grown is just what they've heard.
I refuse to limit myself to one type of light. Just as I refuse to limit myself to one method of growing.
Many of us that already have existing HID equipment and cheap electricity it makes no sense spend a bunch of money on new LEDs to get the same result. I do have issues with heat in the summer but I just grow some plants outdoors and pay nothing for electricity. It's also nice because I just treat them like the other plants in my garden. Just hit them with the hose to water them and give them some food from time to time. Easy peasy and a nice break from the indoor garden. It's a vacation somewhat.
Just get the best light you can that you are able to fit into your environment, fit's your budget, and grow some damn weed. It doesn't matter if it's LED or HID.
