Finally - a Canadian source for 4ft T8 LED Ballast Bypass tubes at a reasonable price. Ballast Compatible tubes are available at many local places selling lighting, but I've been looking for Ballast Bypass tubes for over a year and have only found one place that sells one, but they want too much and will not discount by the case. I came across these Shopper+ Ballast Bypass LED tubes a while ago and now that they are on sale for a decent price decided to order and try a box of 10 (which makes them half the price of the one sold locally). After installing 4 in a 2x4ft fixture a light meter showed them as bright as the new 40Watt CW (cool white) fluorescent tubes in the adjacent fixture using 1/3 the power (64W rather than the 204W that 4 Fluorescent tubes and 2 ballasts require). Something to note is that the color temperature of CW Fluorescent tubes is 4100K where as these LED tubes are 5000K. And just as CW Fluorescent tubes appear white compared to WW Fluorescent tubes, these LED tubes appear white compared to CW Fluorescent tubes so you'll want to re-lamp all fixtures in a given area as these 5000K LED tubes will make any with CW Fluorescent tubes appear as if they have WW tubes. (See my photo with the new LED tubes in the closest fixture and CW Fluorescent tubes in the far fixture). Measuring the Lumens from the fixture with the LED tubes and one with CW Fluorescent tubes showed they were about the same, but the whiter light from the LED tubes make them appear much brighter. Now I need to order more tubes for the other fixtures in my basement and garage workshops so I'll no longer have to deal with failing and noisy ballasts or have to wait for the fluorescent tubes in the garage to warm up when turned on in the winter before having enough light to see.

My first review on March 10th is below after buying a case of 10 tubes (I wanted to ensure I would be happy with these tubes before buying more). Following that I purchased a case of 30 to finish off my basement workshop and start on the garage workshop. One correction that I need to make to my first review. The measured brightness is actually twice that of 40 watt CW tubes. The first review was written after only re-lamping a single 4 tube fixture and now that over 80% of the fixtures in the garage are done I find that the measured light level is actually twice what is was before. As for power savings, some before made a comparison using using 80 watts as the power required to light two 40W fluorescent tubes, but the ballast also requires some power to operate and the actual power required for two 40W fluorescent tubes with a ballast is about 100W (104W each for several I measured). Each of the 40 LED tubes received worked perfectly and I've already ordered another case of 30 to finish off my 2 workshops and a few other fixtures in the basement. P.S. The person that reported the bulbs didn't work, but others from Costco did, must not have read the instructions or understood what "Ballast Bypass" means as Costco only sells "Ballast Compatible" tubes.

These T8 LED tubes are ever bit as bright as the 40 watt fluorescent tubes at less than half the power consumed. Your installation guide, for removing the ballasts and rewiring, was excellent. I also appreciated the short delivery time. Overall very pleased with this transaction. Looking forward to the long service life expected. Thank you,

Missed these on offer on boxing day. Waited a full 11 months for them to come back on for black Friday. Well worth the wait and even saved a bit on the price from 11 months earlier! Nice and bright and easy upgrade if you're happy rewiring the fixture to remove the ballast. Highly recommended.

Big energy saver plus longer lasting bulbs. Remember to check whether you are going to bypass your ballast before ordering.

Excellent product nice white light easy to convert half price on Black Friday should have ordered more ran out of tubes before getting all lights converted
