I had a hard time finding a replacement for my new light fixture. I was happy to find it here. The price was great and the delivery was fast. Will purchase again.

Quick and easy ordering.

I was concerned that a single fluorescent bulb may not survive shipping. Well packaged. It survived just fine. You shouldn't, and don't have to worry, if your product will be safe.

Very Pleased With These Lights
April 24, 2013
I gotta say that I was a bit skeptical about ordering these lights online. I've tried ordering them before from a different retailer and was never quite satisfied with the product when it arrived. The bulbs were either broken or not very good quality, which kind of discouraged me because I cannot find these locally so if I wanted them I had to order them online. I'm glad I took a chance and ordered from Pegasus Lighting though because I got the bulbs in record time (3 days with free shipping!) and my order was packaged so well, that even if the box fell off the UPS truck, it still would have survived. To make things even better, the price is one of the lowest I have seen and I have done a lot of research on these T5 bulbs. The bulbs themselves seem to be very good quality and are nice and bright. They go good in my office and I will definitely be ordering from this site again and recommending it to friends.

Questions & Answers
By Kathy from Rossville, Ga. on November 11, 2012
When you measure to get the proper size bulb, do you measure from pin tip to pin tip? I have one that is 32.5 in. from tip to tip. What size do I order?
By Jacob from Pegasus Lighting on November 12, 2012


Our measurements we provide are the 'nominal length', which is the length of the light bulb end to end including the proper allowance for standard light sockets.

Based on your measurement, it sounds like you are looking for this lamp:

By Christine Del Re from on May 29, 2014
My fixtures (vanity bath bar) require :
(2) 24 Watt 120 Volt Type T5 H.O. Mini BiPin Fluorescent lamp (not included).

Dimensions of the fixtures:
23.5 in. Option: Height 3", Width 23.5", Depth 2.75"
Pls advise, I can't find these at the stores. I would like soft white, something not so harsh.

Thank you
By Chris from Pegasus Lighting on May 29, 2014


This is the lamp you need for your fixture. We suggest that you choose a 3500K color temperature (neutral white) for your application.

What is the lumens rating on this lamp?
By Jacob from Pegasus Lighting on May 18, 2015

2,200 lumens.

By Cory from Ohio on October 4, 2012
Are the bi-pin ends on these bulbs the same as the mini bi-pin of the "Philips 24-Watt Cool White 85 CRI T5 HO Fluorescent Light Bulbs" or are these two separate and incompatible? I need the mini ones, and I thought they may be the same since the bulb diameter is the same for both.
By Jacob from Pegasus Lighting on October 5, 2012


You are correct, this lamp also has a mini bi-pin base.

By Diana from New York NY on October 2, 2013
I am trying to find bulbs that fit into a Lutron ECO-10 10% ECO-T524-120-2 ballast. I am having no luck. Some places even list this ballast as discontinued. Is it possible to still get light bulbs for this? Or an i just out of luck?
By Pegasus Lighting on October 3, 2013


I found this spec sheet on Lutron's site -

Here is lists that your ballast takes (2) 24W T5HO.

These light bulbs are 24W T5HO, so they should have no problem working with your ballast.
