Question from Joan L:

We have T5 fluorescent fixtures that were from slim fluorescent (Savio lighting). Will the T5 bulbs you have fit them? We have 21W and 35W fixtures. The specs for the 35W on Savio give 57-5/8in length and for the 21W it is given as 34in. My measurement of a 35W bulb we have looks as though it is 57.5 in including the pins.

Answer from Pegasus:

Yes, these T5 light bulbs will fit.

Question from Jay:

Is it possible to find the exact measured length for this product from pin to pin? The only reason I ask is my display cases will only fit a bulb measuring 32.5in. I have tried 34in bulbs. I have not had one fit yet. The Display cases were manufactured in China. I have about 10 cases in my store.

Answer from Pegasus:

33-15/16 inches from pin to pin. This lamp will not fit in your display case lights.

Question from Marie Kochaver:

Does this need a starter or separate ballast?

Answer from Pegasus:

Yes, this T5 fluorescent light bulb requires a ballast.

Question from Shauna:

Will this fit a Westek Portable Cabinet light Model# FA435HBL 120VAC 60HZ 21 W?

Answer from Pegasus:

Shauna, The specifications I found online indicate your fixture is about 34.5 inches long. This light bulb is the right length and wattage. I would assume that the fixture uses T5 fluorescent light bulbs, but to be safe, if you have the old light bulb, simply measure the diameter. If it's about 5/8 of an inch, then this light bulb will fit.

Question from CJ:

Will this fit the utilitech 34in fixture from Lowes?

Answer from Pegasus:

Yes, I think these light bulbs should work just fine in that fixture.
