    Comments about Philips 25 Watt, 36 Inch T8 Cool White Fluorescent Bulb:

    My wife and I are full-time RV'ers, and therefore we need to have things that work. Recently the fluorescent tubes in big kitchen started going out. We use that particular light most of the day, whether we use additional lights or not.

    I was at a loss where to find them, that apparently the 25 Watt, 36 inch T8 Cool White Fluorescent Bulb is not widely used. Searching the internet, I found Bulbs.com. The personal were very helpful in finding replacements. The tubes were shipped in a proper container and arrived in perfect shape.

    If you need replacement bulbs or tubes, please consider shopping with Bulbs.com.
