Do i need to change eballast? Do ballasts have lifespans?
I have changed a few PL lights tube. They are new and bright but plants do not bubble. Water conditions are ok. CO2 ok. I am certain its the light set...

hi bro. while lights do play apart in making plants pearl, so are the fertilizer levels in the water column. Mind sharing your setup specifications? light wattage, tank, etc..

yes. the ballast do have a lifespan.
however, the performance does not really degrade much over its lifespan.
it's either its working or its not working.

My 4ft DIY lightsets uses e-Ballast and they have been around for the last 8 years. Absolutely no complaints at all. Thumb ups.

Sometimes it also depends on the quality of the ballast.....thats why the price can tell the difference.

Hmm where to buy eballast for T5HO lamps? I have an aquazonic lamp with a faulty ballast and I do not know where to replace it except buying a new lamp...
