PARMIDA 20-Pack 4FT LED T8 Hybrid Type A+B Light Tube, 18W, Plug & Play or Ballast Bypass, Single-Ended OR Double-Ended Connection, 2200lm, Frosted Cover, T8 T10 T12, UL - 5000K

Bulbs shipped fast. Installed two cases five months ago and all forty are still working. Nice and bright.

These bulbs are amazing & I've purchased multiple cases over the past few months & they beat the original bulbs installed & not as harsh on the eyes.

LED lighting is kind of a hobby of mine. I have updated the lighting in several industrial buildings at relatively low cost with excellent results. Not all of the replacements have been straight up fluorescent tube so I have used several different types of bulbs/fixtures depending on what was previously installed. One building had 400w mercury vapor lights and another had E27 sockets. There are countless options out there. If you already have fluorescent fixtures I don’t think there’s a cheaper or easier LED replacement than these.This purchase was for use at home in my kitchen, closets, and garage and so far I couldn’t be happier. I was looking for something with a frosted lens as I wasn’t totally happy with some Hyperikon fluorescent LED replacements that were clear. The Hyperikons were more heavy duty and bigger with aluminum frames. They may also be a touch brighter but with the light directed down it made the ceiling and upper walls dark giving an overall feel of the room being dark even though more light was actually reaching horizontal surfaces. These lights give a much softer less directional light that feels more like a fluorescent tube. They are very lightweight and don’t seem as sturdy but they give no indication that they are delicate. The 4000K light is nice, Neither too yellow nor too blue. It feels like incandescent lighting. In my kitchen fixtures I replaced two 40w fluorescent tubes with one of these. In my photo the 3rd light from the left is still two fluorescents. The light output from one of these LEDs measures about 300 LUX while the two 40w fluorescents are about 250 Lux. In the garage 4 LED tubes are more than double the measured light as 4 aging 40w fluorescentsI’m about 50/50 with the lights working on the ballasts and that’s not too bad. Bypassing the ballasts couldn’t be any easier though and should probably be the standard. I haven’t tried the single end connection yet but for the double ended you just take all the wires coming from the tombstones at one end and attach them to neutral and you take all the wires on the other end and attach to the hot. A couple wire nuts and you’re in business.Time will tell if the drivers are going to be long lived but so far so good. I have installed 15 of the 20 bulbs I purchased and every on of them has been good. If they start pooping out I’ll try to come back and update but so far five stars.

Update April 22, 2022I installed 12 of the tubes and one week later 1 of the tubes stopped working. I ensured the tube was properly seated and retested, still bad, would not light. On 4/22/22 I submitted an online warranty request to Parmida for a replacement. The online form requires you submit a photo (crazy). I will update this review in days to come, depending on my experience.These tubes arrived in good packaging and in good condition. The tubes are packaged in foam that helps protect against shipping damage.Before ordering, I watched the video at the order site. The video is excellent and should be watched before ordering. The tubes are sold as hybrids meaning they will work with many existing ballasts or you can remove the ballasts. I installed mine by leaving the ballasts in place. Voila, they worked perfectly and are very, very bright. I am hoping these have a long life, like many LED bulbs have experience with. I am looking forward to winter, many have commented about the instant on/bright feature of these even in cold weather.I am happy to be rid of the fluorescent tubes which take a while to come to brightness in cold weather. I had a number of problems with the Sylvania 10pk fluorescent tubes I purchased from Home Depot. Several of the new bulbs were bad when I went to use them. Others would last only a season or two. The LED tubes are much easier to handle and install than are the glass tubes.I am hoping the life of these LED tubes will match the experience I have had with other LED lights throughout our home. Will follow up on this in (hopefully) a number of years.

Great lights best value. 4th case I have ordered.

I purchased 3 cartons (60 lamps total) of these "plug & play" lamps. Of the 60, about 10 failed in the first few months. Today, one right above my desk caught on fire, falling to the ground next to me. It also smoked the tombstone receptacle in the fixture. Thankfully it didn't hit me. I have contacted Parmida NO-Customer Service about the first lamps that failed and NEVER heard anything back. I reported the fire this AM but don't expect a reply.DO NOT BUY THESE! They are a fire hazard. I'm going to post this review in as many places as I can and am headed to Home Depot to shell out several hundred $$$ to replace these Parmida tubes.From the Amazon product description:CERTIFICATIONS: This product meets strict requirements to ensure that they are safe and reliable. UL-LISTED to avoid electrical shock and fire hazard. RoHS COMPLIANT (Restriction of Hazardous Substances) and FCC Certified making our T8's extremely safe.These are definitely not "EXTREMELY SAFE" and will be reporting this incident to the listed agencies.

These bulbs are great! Multiple installation options, ballast or no ballast. So far the bulbs have all worked with no quality issues at all. Also they haven't had a single one burn out yet. Can't say that about normal fluorescent bulbs! Also not to mention they are way less expensive than other brands I have used.
