Wide angle and highly diffused with no diffraction, lighting appears relatively natural.
Definitely follow the factory recommendation about open air mounting.

This should be interesting, thanks for running this test.

Hopefully this will help with the myth that LEDs don't produce much heat:-))
 
Thanks for doing this, Jim. I considered trying one out, but would prefer to see how your trial goes first.
 
The 141.5F was measured about half way up the heatsink.
Ambient temps were approx. 72F at time of measurement

Wow, that is pretty hot to touch
 
Cooling of these led lights is always undersized. I would rig a fan to cool off the heatsink. Extends the lifetime of the lamp, too.

Ping growth, one month

Draw your own conclusions... ;-)
Think I will swap plants out this week,

Note: The dead material and APS do not appear so pink to the eye, they appear "normal".
I believe my cell phone camera is sensitive to the far red LED.

Do you have a "control" plant growing under "typical" lighting to compare it against?

No control? Hmm, I taught you better....:0o:
 
  • #11
Science is about proving yourself right, not the alternatives wrong ( All praise thee, Jerry Falwell :angel: )
 
  • #12
the intent was never if it was better than light "A" or "B", but if it would grow plants on its own...

so meh :p
 
  • #13
Looking good B. :) Thanks for sharing your results.

Any and all updates on LEDs is greatly appreciated. I'm loving mine but they are nothing like these.
 
  • #17
thank for that. I plan on making a change soon and this seems like an easier option for me. im not good at wiring up lights.

Just be careful which ones you pick I "stole" one of my wives Current Satellite Freshwater LED+ to test on some Cephs and they are still all green after many months, the underwater plants the LEDs were designed for are growing like mad thou. So the product is working for its intended purpose but I can't use them as a CP sub :(

Recently arrived ceph division was put in there a couple days ago

Ping has received no other lighting but the LED...
Distance to light is about 12-15"
