Gumby Posted May 27, 2012 Share Posted May 27, 2012 Interesting. Thanks for the info. I now don't have to feel guilty leaving my bulbs in for as long as I have. Link to comment Share on other sites More sharing options...
ThePremiumAquarium Posted May 27, 2012 Share Posted May 27, 2012 This is a good article but remember that total PAR output doesn't always mean that the spectrum the lamp is giving off is desirable after a certain period of time. Link to comment Share on other sites More sharing options...

kev311 Posted May 27, 2012 Share Posted May 27, 2012 There was a huge difference in light output with my xm's after 12 months use, I actually didn't know how bad they were until I replaced them Sent from my HTC Glacier using Tapatalk 2 Link to comment Share on other sites More sharing options...
stylaster Posted May 29, 2012 Share Posted May 29, 2012 I personally know Sanjay Joshi (the one the author quotes from) He has done a lot of bulb research since the mid 1990s. Sanjay is very methodical and i trust his research Link to comment Share on other sites More sharing options...

Sanjay is very methodical and i trust his research Yes he is the master when it comes to lighting. He pretty much wrote the bible on metal halide bulbs and now LEDs.

Mandinga Posted May 30, 2012 Share Posted May 30, 2012 A very experience reefer told me that Radiums put off the best light at 18 months. My current bulb is about 16 months old. Link to comment Share on other sites More sharing options...
