ADL Supply Expert Application & Replacement Guide

Small T5 miniature lamps like this one are commonly used in compact fixtures such as under-cabinet lights, display and showcase lighting, and other small fluorescent luminaires. Because the tube is only 5/8 inch thick, it is made for fixtures designed for this lamp size and cannot be swapped into standard T8 or T12 fixtures.

Many small lamps look alike, so the safest way to order is to match the wattage, length and lamp code printed on the end of your existing lamp (this one is 8W/840) before you buy. If you are unsure, call us and we will help you match it.

What the Color Temperature Means

Will This Lamp Fit My Fixture?

Run through this quick checklist before you order:

• Base: Check that your fixture uses a G5 socket, which has two thin pins about 5 mm apart. T8 and T12 lamps use a different, larger base.
• Length and wattage: Match the wattage and length of the lamp you are replacing (8W, 11.9 inches).
• Color: Choose the same color temperature as the other lamps in the same room so they match.
• Ballast or starter: Confirm your fixture uses the ballast or starter type it was designed for.

Frequently Asked Questions

Is this lamp a direct replacement for my old lamp?
Check the wattage and lamp code printed on the end of your current lamp and match it to 8W/840. If the base, length and wattage all match, it will fit.

Can I mix different color temperatures in one fixture or room?
It is best not to. Lamps with different color temperatures look noticeably different side by side, so replace lamps in a group with the same color.
