HID's, LED's, or T5's?

I was looking around for a light that would produce less heat then the HIDs, and came across a few others mainly LEDs and T5s. I was just wondering if I could get some input before I purchase anything, pros and cons of the less heat, energy efficient lights. Compared with the HIDs would the T5s or the LEDs be more worth it. I have a 5x6 space and need less heat but more light, I currently have 1 600w HID on and I could control that temp, I wanted to add another light that would not effect my temp very much. If anyone with any input please let me know thanks.

Ps. I need the other light for bloom

I would suggest trying a verticle setup before you get another light. I made the switch a couple weeks ago and am liking the results. It helps keep the room a little cooler cause the heat isnt building up around the hood and you get 360 degree coverage from the light. Otherwise, I recommend LED over t5. I love my t5 for veg, but it dont have much penetration. A good LED does.

Ceramic metal halide is ur answer. Dropped my temps over 5 degrees compared to reg mh bulb. Google advanced tech lighting cmh and watch the videos.

Same bulb can be used for veg n flower. Just started flowerin mine with a cmh for the first time

I love my T5's for veg. but I don't think they would be good for flowering. I would rock out with another 600W HPS.

I have another 600w hps and I put both of them in the room and my temp was at 129 degrees F and after I vented the room and did some more work I got it down to 99-101 degrees F which is too high still, so I figured that I would get an led to hang right along side of my hid. LostNUG 5 degrees won't help me alot but ur idea is noted for next time, somedude247 ur idea is preety good so by hanging the light in vertical position it would produce less heat and give me 360 degree coverage will def look in to that but it's too late for this time ur growing with leds right?

that's super hot. you can't get AC to where you are doing it??

Lol i know it is very hot that's why I want to get an led instead of this other hid that i have, and I could bring it down to 99 degrees with an ac vented to the room but that is the lowest I could bring the temp down to, with 1 hid I maintain the temp at 78-80 degree F with the ac vented to the room.
