I checked
Sanjay's Lighting Guide before I ordered. The difference in efficiency between the two lamps is double!
I have an Icecap Ballast and an ARO Ballast. I can only compare to the Icecap.
The efficiency of the XM compared to the Aqualine is
XM: 0.1607
Aqualine: 0.3388
Even other 10k bulbs could not hold a candle! I cannot wait to see the growth I get out of these!!!!!!
Why would you compare the 10k AB to the 20k XM. Wouldn't 10k to 10k be more relevant? According to the same site, the XM has an efficiency of .3755, and a higher PPFD than the AB, so why not that one?
