Easier to do than I thought it would be. The main thing is to make sure you have a electronic ballast like it say to on the bulbs

I replaced 8 fluorescent bulbs in my garage/work shop with the Lumen bulbs. When my wife turned on the swith to be sure they were all working I couldn't believe my eyes. The difference was like night and day. I am thrilled with the brightness and I'm sure it's going to be much easier and more pleasant to work there now. Might even cut down on the number of mistakes made.

does this have to 2 pins on each end?
Steve R on Nov 23, 2017
BEST ANSWER: Yes, they protective caps the protect the two prongs
Does this bulb require removal of the ballast?
Philipp2 on Nov 23, 2017
I understand that there is no need to remove the old ballast from the light fixture, just remove and replace the tubes. But, what about when the original ballast fails, will I need to replace it (the ballast)? The description says that these tubes operate on 120 volts, but the ballast puts out a different voltage. Am I confused? Yes.
LAWRENCE H on Mar 5, 2018
BEST ANSWER: Yes, with LED bulbs that require a ballast, as these bulbs do, if the ballast fails, you need to replace it or these bulbs won't work. A fluorescent ballast when used with fluorescent bulbs will use about three watts itself, apart from the watts used by the bulbs themselves (though I don't know if a ballast uses less power when it's used with LED bulbs), so the most energy-efficient type of LED T8/T12 bulb is one that doesn't require a ballast, but that requires rewiring the light fixture, which can be a hassle. The residual three (or fewer) watts used by the ballast, when it's left in the circuit, is pretty minimal when you consider the reduction in wattage you get by replacing fluorescent bulbs with LED bulbs--a minimum savings of 14 watts per bulb if you're replacing 32 watt fluorescents, or 22 watts if you're replacing 40 watt fluorescents.

I don't know the answer to your other question about the voltage difference.
Are these led's used with or without existing ballast, and if so, which ballasts will work?
Thomas T on Nov 24, 2017
BEST ANSWER: WE did not remove or change our light's ballast; and, there were no instructions regarding ballasts in the package with the LED replacement bulb.
Does this have plastic around the LED's to protect them and make them shop safe from breaking glass it they are hit accidentally?
Tim S on Nov 23, 2017
BEST ANSWER: Yes. The LEDs are in a clear frosted plastic tube shaped just like the T8 & T12 fluorescent bulbs.
Does the existing ballast need to be removed and the fixture rewired?
Mack D. on Nov 24, 2017
I have both 8’ and 4’ floresent fixtures. How do I tell the difference between T-8, T-10 and T-12 bulbs?
M N on Mar 10, 2019
BEST ANSWER: The number *8, 10, 12) refers to the diameter of the tube in 1/8". Thus, a T8 is 1" diameter, a T10 is 1-1/4" (10/8") diameter, and a T12 is 1-1/2" diameter. The ballasts for these are different. A T8 bulb will not work on a T12 ballast, nor will a T12 lamp work on a T8 ballast. In addition (less important?), for a precision luminaire, the optics are also different. A striplight-- not so much.
What happens when the existing ballast goes bad?
James R on Jan 5, 2018
BEST ANSWER: Replace it.
If the ballast goes bad will these still work?
Hubert B on Jan 17, 2018
do they have these for t-12 bulbs?
tom f on Jul 4, 2018
Do you have to remove the ballast?
Bob B on Feb 22, 2020
BEST ANSWER: No you don’t. As long as it’s a rapid start ballast and doesn’t have the old style aluminum starters in the fixture.
Direct replacement as long as your ballast is good.
Are these bulbs 1" or 1 1/2" pins ?
tom p on Dec 22, 2017
BEST ANSWER: The pins are 5/16" long and 1/2" apart.
I just replaced my old light fixtures with 4' LED replacement bulbs. The bulbs seem to go out when there is no movement. Is that normal?
Anthony T on Aug 27, 2018
BEST ANSWER: No, not at all
Is the existing ballast needed to drive the LED bulbs, or can it be removed?
Ron O on Mar 12, 2018
BEST ANSWER: As I read the directions you need to leave the ballast in place this bulb doesn’t have a built in power source.
Will they work well in cold weather?
Badknee on Jan 30, 2018
BEST ANSWER: They are not affected by low temperatures.
Will led replacement work if ballast is defective?
Randy O on Apr 13, 2018
BEST ANSWER: No, the ballast is required for operation
Do they make an 8' version?
Darrell H on Mar 12, 2018
BEST ANSWER: I have no idea!
Can this bulb be used to replace older T12 fluorescent bulbs or is it only a replacement for T8's?
Donald M on Feb 8, 2018
BEST ANSWER: I don't remember the difference between t8 & t12 bulbs but I can tell you this the bulbs are the kind that have 2 prongs on the end. I had talked to another individual that had replace regular bulbs to led bulbs and was given to believe that I was going to have to bypass the ballast. When I received the led's all I had to do is replace them just like a regular fluorescent. The only difference is that the led bulbs have a shade on them that directs the light down so one has to make sure that the shade is positioned upward toward the fixture rather than pointing outward, but that was no big deal.
Is this a direct plug in? Can someone who's installed them please answer. HD sells a similar product, but once opened, the instructions said to eliminate the ballast on the existing fixture.
Sam on Dec 10, 2017
BEST ANSWER: YES! Remove the old fluorescent tube and insert this one. It is a direct replacement.
If one just replaces the bulbs without having to rewire, are you loosing the LED energy savings?
Buzzz on Mar 5, 2018
BEST ANSWER: I plugged in my old fixture with 2 fluorescent bulbs into a kill-a-watt meter, it read about 74 watts, I then put in the 2 LED bulbs and it read 52 watts.
can this bulb replace a 4 ft T12 bulb (1.5 inch dia vs the 1 inch dia of the T8)?
John N on Jan 21, 2018
BEST ANSWER: I'm confused. The description says this CAN't be used to replace T12 bulbs, yet a couple people have said they did that with no problem. I'd prefer not to buy them only to find they don't work in my fixtures.
Does this light require a ballast to work? My ballasts are bad, do not want to replace.
none n on Jan 17, 2018
What frequency or wave length is this light? 2700 Hz warm light vs 4500-5000 bright antiseptic operating room white? How many watts does it use?
Albert M on Nov 29, 2017
BEST ANSWER: from the technical specs: the color temp is 4000 and the watts are 18.
How do i know what bulb i take, t-8 or t-12? If i need a t-12 where would i find this same bulb?
Dennis C on Jul 15, 2019
BEST ANSWER: The number *8, 10, 12) refers to the diameter of the tube in 1/8". Thus, a T8 is 1" diameter, a T10 is 1-1/4" (10/8") diameter, and a T12 is 1-1/2" diameter. The ballasts for these are different. A T8 bulb will not work on a T12 ballast, nor will a T12 lamp work on a T8 ballast. A T8 (1"D) lamp/ballast requires 235mA of current, whereas a T12 (1-1/2"D) uses 430mA. These are rated for the 235mA ballast.
