4 Pack F15T8 LED Replacement Bulb, 840lm,100-277V,7W

I replaced some display lights for a cake and cookie shop. These brought the displays back to life and really showcased the product. I liked the lamps being able to rotate to aim the light toward the products instead of just being aligned with the sockets.

Used these to replace the fluorescent bulbs in my slot machines. They worked right out of the box, and did not need any rewiring of the ballasts. They do not generate heat or any noise and have really brightened up the display of the reels.

I replaced the fluorescent tubes in 4 under-counter fluorescent fixtures with these, and they are great! I like the color temperature, but best of all, no more ballast hum! The hum had gotten louder over time, to the point of annoying in our quiet home, and we were sick of it. These do require some rewiring of the fixture, to eliminate the ballast (and starter) from the circuit, which I was able to do easily: YMMV. Much easier and cheaper than replacing all four fixtures with LED under-counter fixtures.

One of the 4 bulbs was defective. This can happen, but after contacting customer service the only option I was given was to return all 4 bulbs for a refund. They wouldn't let me just return one. This order took a week and a half to get to me and the box was pretty beaten up.

The lamps work just fine. The fit is really tight. My old flouresant light fixtures normally need a small starter to startup the flouresant lamp. When installing the new LED lamp, I needed to remove the starter and the lamp lit up just fine.

I'll address some of the other reviews here. Some have reported not receiving an installation guide, so I'll attach photos of what came with my order. The directions were actually attached to the other end of the tube they were shipped in, and not immediately obvious until I peeked inside. These are *not* a direct replacement for a fluorescent tube. So please take the time to read and follow the instructions for bypassing the ballast before using. You'll need wire-cutters, wire-nuts, something to strip the wires, and a screwdriver. Search YouTube for "ballast bypass" and you'll find plenty of videos showing step-by-step what is required. There are two general methods for rewiring, so note that these tubes require the live wire to be attached to one end of the bulb, and the neutral wire attached to the opposite end. Some have reported that a ballast bypass is not needed, while at least one reviewer reported a fire hazard from not removing the ballast. Maybe you like fire hazards, or maybe you just love that 60hz ballast hum, but do yourself a favor and bypass it anyway! As is common with LED tube lights, these lights are directional. There is a "light side" and a "dark side". Note that the pins on either side of the tube can be rotated a full 180 degrees, as can the entire bulb within its fixture. There is a 0% chance that you won't be able to get the dark side of the bulb to face the inside of your light fixture. It might take some fiddling around to get it right, but it will definitely work for you. One last thing... bypass your ballast. :-) It's really quite easy. If you're scared, good for you; maybe you should be! In that case, just ask a friend or neighbor to lend a hand.

What a difference these lights made from the original fluorescent bulbs. Whiter in color and so much brighter…not to mention I will probably never have to replace them again while I own this motorhome. I would say these upgrades are worth the increased price of the led bulbs. Lights came quickly and packed well…I highly recommend!

The bulbs came individually packed in a cardboard tube which prevented them from being broken. They fit perfectly into our light fixture. I highly recommend using this seller ad I had to contact them with a question on the bulb and they were extremely fast answering me.

Always a little confusing when one needs to remove the ballast and starter.

blueplanet2000 Will not honour the warranty on the defective products that they sell. Seems to be blaming the wiring when in fact it’s the item.
