Rated hours life wrong
September 11, 2015
Nice color rendition, but no way do they last anywhere close to the 6000 hour rating.

Great Light but Short Life
September 21, 2013
These are quality bulbs and work very well for a set of under kitchen cabinet lights we bought. However, the bulb's rated life is inaccurate. We are frequently replacing them each year yet they run on a dimmer with the fixture switch set at the low setting for about 6 hours/day.
Bright warm light
Manufacturer's rate life is completely inaccurate. Not even close to rated life.

A bulb is a bulb
February 26, 2013
No choice here. This is the bulb that fits the fixtures. The light is much prettier than a fluorescent bulb and that's why I chose the fixtures. I also bought the fixtures from Pegasus - about two years ago. Pegasus' prices are competitive and the service is great. My bulbs came in about two days!
Light is a pretty color and the bulbs last a long time.
Pretty pricey at almost $4 a bulb.

Xenon Light Bulbs
January 14, 2013
I purchased the under cabinet xenon light fixtures from Pegasus Lighting 5 years ago. Of the 9 original 20-watt G8 Xenon Bipin Light Bulbs for those fixtures I've only replaced 3 of them so far. This was my first order of replacement bulbs. I still had an original package of a replacement bulb, so I knew exactly what to order. Even if I hadn't had that, the picture on the website is so accurate it would be easy to recognize. The website is easy to use and the order came within a week. These bulbs also give out a lot of light for being so small. The only drawback is that they do throw some heat, but I don't mind that in the winter.
Easy to put in the light fixture Give great light Long lasting
Gives off some heat

I got my items quick and in great shape. Packaging was nice and clean. Nice website, easy to view the items.
It was exactly what I needed. They don't sell these types of bulbs anywhere around where I live.

Long-life bulbs
October 18, 2011
I installed under counter fixtures in our kitchen about four years ago and have been averaging two years life per bulb, with the lights on an estimated six to eight hours per day. They give off much less heat than the halogen bulbs that I had in the previous lighting installation.
Long life, reasonable price, runs cooler, even light distribution to the workspace, very quick and easy to replace in the under counter fixtures.

Questions & Answers
By Mike from Beacon, NY on March 1, 2013
My big problem is finding a T4 shaped bulb, G8 base, BUT THE circumference of the bi-pin is fatter than most that I have tried to replace with. Can you tell me what the dimension of the prong(s) are?
I measure .50 on a dial caliper for the old bulb.
By Avner from Arlington, MA on March 4, 2013

Each prong for this bulb is 0.050" and measuring both together from outwards gives 0.36"

By Kathy from Duluth on March 6, 2013
Is the illumination COOL BRIGHT WHITE? I've purchased several replacement bulbs recently and they all throw warm light which barely illuminates the counter of my kitchen.
By Jacob from Pegasus Lighting on March 7, 2013


These emit warm white light similar to that of a halogen light bulb.

The term cool white is usually used to describe a color temperature of about 4100K, which is more typically found in fluorescent light bulbs.

By Kara from IN on February 28, 2014
Hi, my current bulbs say 20 Watt XENON T4 CLEAR G8. What does T4 mean; and will these bulbs work in my lights? Thanks
By Jacob from Pegasus Lighting on February 28, 2014


T4 refers to the diameter of the light bulb. This items is a T4 light bulb.

Yes, I think these light bulbs will work in your light. They are a 20W T4 G8 Base with clear glass.

By Bruce Butler from Yarmouth, ME on October 5, 2013
I'm looking for a 2620 degrees Kelvin Xenon T4 G8 120v, 20 watt lamp. Is this what you offer? I need to match the color of what I already have.
By Jacob from Pegasus Lighting on October 6, 2013


This light bulb is similar but not exact. The color temperature is 2800K.
