which light set produce most heat?

[dnsfpl]

2 x 150w MH = 300w

6 x 54w T5 = 324w

2 x 160w LED = 320w

thanks for your input

I think 50w MH produce even more heat then t5 and led

[Clement_jr]

it gotta be MH

[sunnymau]

MH

[dnsfpl]

how about T5 vs LED?

LED is close to no heat?

thanks

160w led I presume would be the maxspect razor 160w version?

[Clement_jr]

led also have heat, but t5 slightly more than led

[sty68]

Led less heat and less power consume.

thanks for sharing

Pls correct me if I'm wrong, but you have to be very careful when you talk about LEDs consuming less power. It still depends on the wattage of the lightset you are using.

For example, if you use a 2ft 4 tubes T5 HO, which consumes 24W per tube, your total power consumption would be 96W. If you swap to a Maxspect G2 110W, your power consumption would naturally be 110W. Active cooling of the LEDs also add to power consumption. However, this is not inclusive of savings from chiller kicking in less, etc, but just a direct comparison.

I'm just stating that it doesn't mean using LEDs immediately equals savings. You have to do your own math.

I'm running 4x 39w T5HO in a small 3ft frag tank and tested without chiller is 31C (All light on) and 30.5C (All light off) not much different ...

I'm running DIY LEDs and I think based on same wattage, LEDs actually produce more heat than T5s as the beams are more focused.

So I will rank them MH > LED > T5 (wattage for wattage).

However, if you have sufficient air movement to cool your tank around the top of the tank, I'm thinking MH > LED = T5

MH is easily the hottest.

I could PM you the photo of my DIY LED if you like.. Let me know?

thanks all for the detailed explanation

i believe a lot of reefers will benefit from your experience

happy reefing
