UVB LED Vs. MH (1 Viewer)

Yeah so this is pretty interesting.
Marc Levinson, Andrew Sandler, Tulio measuring spectrum profiles and evaluating MH performance compared to LED. I’m not a huge YouTuber but this is kind of interesting. Where did I put those mh ballasts?

Something is afoot however. They measure the temp output from both MH and LED @100% output. As someone pointed out in conversation, Why do I need a chiller when running MH and not so much for LED?

because wattage is not the same.

led is more efficient. If you believe the led manufacturers, a 90 watt led is equal to a 250w metal halide. A 215 watt led is equal to a 400 watt mh. Because the leds are more efficient in creating light without creating excess heat in addition to light.


edit:

in the video they are comparing a 250w metal halide vs 215w of the radian. 35w delta isn't much.

I have one small cheap fan (I believe Greg told me about 3 yr ago) that manages my temp for (2) 250w Halides and (3) XR15 G5’s. All these years I thought for sure I’d need a chiller. Tullio’s RB’s run much cooler. I left my cell phone on top for hours one day. Never melted it.

Last time you didn't come over. Forgot how heavy they are.

You can see the housing is more efficient.
