Collection LED Tube / 19 Watts / 40 watts CFL replacement / 1611 lumens / Daylight / 5000k / 40,000 hr / 2 yr warranty / 2 packs

Pros: VERY NICE. Bright daylight in our kitchen now. Replaced two 40watt daylight florescents with these and wow, what a difference. They use 1/2 the electricity, last longer and are brighter. Cost effectiveness is negotiable however as florescent tubes are super cheap but, these LED alternatives are far superior in the illumination department. Also cooler, last longer and no noise. Wiring was a piece of cake, far easier than the instructions read. Just kill power, remove the ballast, cap off the wires individually on one end of the fixture and run 115 to one end of each tubes socket. Typically already paralleled wiring exists in most 2 tube fixtures. Took 10 minutes.

Cons: 4 Stars due to two reasons. 1- Cost (and I got these on sale for 45 bucks pair here). 2- 1 second time delay when you flip the switch.

Overall Review: Cost of these is high. Basically, 12.225 cents a KWH is our power bill bottom line. So two 40's at 10 hours a day draw around .8 KWH and with ballast, prob close to 1KWH per day. So, ~$3.68 a month for std tubes and ~$1.50 for these LED tubes at 10 hours a day (if they in fact pull 19watts). So, they can pay for themselves in just over a year at 10 hours a day usage. A good investment.

Pros: Very Bright - My garage has 2 fluorescent lamps with hold 2 x 4' tube each. I was able to modified the the fluorescent lamps with out having to add any new HW. I am using 1 of the LED Tube for each lamp so I went from 4 fluorescent to 2 LED Tube. I also use occupancy sensor light switch for my garage and it seem to caused the standard fluorescent lamp to flicker and burn out quickly. The LEDs seem to be working fine.

Cons: Not that I can tell

Overall Review: after a search about the the different between shunt and unshunt holder I finally realize that the just mean that. Shunt = both connectors on the same holder are wired together. unshunt = connectoors are not connected together. my old holders has 2 cables with the same color connect to the holder on each side. I assumed that they are probably the same and this how Mfg make the unshunt holder work lamp without starter. I check with my multimeter to make sure also. once. So all I have to do is just cut the pair of red and pair of blue on my old lamp and then just wire one red one blue to the black from sw and and one red one blue to the white. That was its. 5 minutes job.

Pros: Easy retrofit Great light output No more Ballast buzz

Cons: No cons that I could find

Overall Review: I replaced 4 pair of the Old style florescent bulbs and ballast . Nice bright light, much better than the old florescent ones.

Pros: Very bright; perfect for garage. Fast shipping. Fair price. Very easy to re-wire (maybe I was lucky!)

Cons: Very brief delay in coming on, but faster than the other fluorescent fixture in the garage.

Overall Review: Very bright white light; probably not what you'd want for the kitchen or bath. Hardest part of re-wiring was having to clean a fixture that had been hanging untouched (except for bulb replacement) for about 30 years.

Pros: Bright, Runs cool, no noise, color is the same as the dying and noise CFL tubes I replaced It's 2 pack deal, so the price is not too bad

Cons: Installation needed to by pass the ballast, which needs some DIY work. But I think all LED needs the same procedure. The video attached on the product page is helpful. I didnt remove the ballast, I just cut the power to the ballast and wire them into one end of the lamp holders, didnt work the first time because I didnt use "unshunted" lamp holder for the end with power. changed that and all is good.

Overall Review: My apartment is all LED now, the money I saved with those lights goes to using AC and heater. works like a charm

Pros: reduced energy, long life, no ballast,

Cons: price, fixture needs conversion, slight delay till turn on

Overall Review: good investment, led efficiency, need basic wiring knowledge for fixture conversion which

Pros: Very bright for my kitchen and garage work area. To my eye "white" rather than "yellow" or "blue". Of course, long term cost savings. Presumed better for environment in both energy use and materials used. Less heat output, a big plus in Houston most of the year. Should last for years. Very pleased.

Cons: Delay in starting. Seems about 1 second in my case. Need to redo fixture wiring, although wiring is simple and a bit simpler than original fluorescent. Just understand and follow directions.

Overall Review: Applied included sticker to fixtures to forewarn "the next guy" about changed wiring. Have seen for sale other T8 (4 ft. by 1 in.. dia.) LED's with different wiring methods than this, but shouldn't need changing for years and years -- and years.

Pros: Newegg shipped these very fast, and arrived in a strong cardboard tube. As others have noted here installation was easy and fairly quick to do. If you can build or swap components in your PC, you can re-wire a flors. fixture to use these bulbs. Very happy with the light output and brightness of these bulbs.

Cons: Would have preferred one with a warm light color for in the kitchen, but minor.

Overall Review: You'll need a few extra small wire nuts before beginning install. Also once your fixture is apart check if your bulb connectors (tombstones) are shunted or not, as the must be unshunted ones for the LED bulbs setup. Just use a multimeter and check them for continuity-if none then you are good to go. (and watch the install video on the product page - way easier than making sense of the convulted written instructions that come with the bulbs!)
