My quick E5 review

[BetURWrasse]

So I purchased two 24" blue pop e5's from a fellow member the other day and got them in last night. Today I popped one in and took a couple par readings.

I normally run ATI B+, P+, B+, B+ (seen on right)
I set up the test light as B+, P+, e5, B+(seen on Left)

To the eye the old setup looks brighter, the new setup does look slightly bluer and not as bright. However it is still daytime and I do have light coming through a window so I will see what it looks like tonight.


So here is the setup: 2x Nano Box Reef T5/Led hybrids hanging 9" from the top of the water. I took readings with a BioTek Marine BTM3000 with the sensor just above the water and another with the sensor approx 1" below the top of the water.

So on to the readings. I turned the led's off and....

Reading on top of water: e5 setup 172 T5 setup: 182

Reading 1" below water: e5 setup 125 T5 setup 140

Adding led on top: led/e5 421 led/t5 467

I am a bit confused by the last line? The T5 is still higher PAR than the E5?

Yes

Interesting. Good to know about the performance of the E5. Thanks for the write up.

Thanks for the post. All in all I'm not surprised really. The b+ is so consistent and holds its part value much longer than other bulbs. There is a thread here where it showed after a significant burn time the b+ still had the same par as when it was new.
