IceCap overdrive a NO

titus · #1 03-28-2002, 10:37 PM

Hello,

Just took a look in my canopy today and realized the new Philips NO Daylight bulb I put in 1 month ago is already showing signs of age. One of the ends is already black and the bulb's output is not even close to its original intensity.

There are 3 other VHOs from URI in the system and all are driven by an IceCap controlled by a Niche Engineering's Solar 1000-L1 in case you are wondering. 1 month life for a NO is a bit too short for me. I just put in a new Philips NO daylight and a Philips NO high-CRI so we'll see how it goes.

thats weird Titus, most peopl say there NO's last over 1 year on the icecap.. mind you I learned how the life of bulbs are rated yesterday and the likely hood of getting one that will fail in 1 month is 2% so you might have gottena bum bulb. you should realy try the GE Daylight Ultra. it has the highest lumen output that I have seen in a NO bulb.. i put a coupld in my kitchen and all I can say is wow. they are about a 6900K and bright.

2) sight seeing :eek:
3) fun time [img]smile.gif[/img]

Short bulb life is when overdriven is not a surprise.

I used to work for a crt display manufacturer that did custom aps for the medical industry. This often involved overdriving the tubes, which in turn lead to a shorter life. The phosphors burn of more quickly.

If it sounds to good to be true, it usually is.
