I'm curious, why do you replace your bulb so often? Typical T5HO bulbs are rated at 20,000-30,000 hours with end-of-life lumen maintenance rated at about 95%.
I'm always keen to find factual, quantitative evidence that backs up the notion that T5 bulbs are significantly dimmer one year into their life. So far I have trouble convincing myself that this isn't a relic of the days when T12 were in vogue.
