questionshas anyone used led replacement bulbs for 4' t-8…



Thanks for the reply.

I'm looking to replace six fluorescent tubes in three fixtures in my basement... nothing on your scale.

My fixtures need pairs of fluorescent tubes but given that LED tubes won't need to be used in pairs, I will probably use a single tube in two of the fixtures and a pair in the third (the middle and bedroom end of my basement don't need as much light as the workroom end). Thus a total of four replacement bulbs, maybe adding one more later.

I guess I just am finding it painful to spend $200 to $300 on four consumer-grade light bulbs.

The Chinese company in your third link sells several bulbs of the type I want, though I may just be better of schleping over to Home Depot: at least I can see the actual color of the light from the bulbs before I buy them (one of my neighbors uses all LED or CFL bulbs and their place looks like some kind of mad scientist lab at night due to the color of the lights).


I honestly didn't know that there were LED replacements for F40T8 bulbs. they also make LED replacements for F96T12 bulbs? BTW I haven't clicked on the link yet...



Yes (see here for one such example).

LED replacements for T-8, T-10 and T-12 fluorescent tubes are generally a long narrow strip of surface mount LEDs (think like the candy dots that came on a strip of paper) inside of a clear or frosted tube (plastic, I presume). Some of the pictures on Amazon make this a bit clearer than my description does.


@baqui63: Thanks for the insight. $100+ for 1 bulb? I hear complaints about $6 for a fluorescent 8-footer! It will be a while before the tubular LEDs make it to my little part of the world.



The LED bulbs cost more initially, but last at least twice as long, use about half the electricity and do not need a ballast. I haven't done any comparisons myself but based on several articles I've read, in commercial applications involving large numbers of bulbs, they save money and are worth using.

Based on Home Depot pricing, it's ~$85 for 3 ballasts & 6 fluorescent bulbs vs. ~$408 for 6 LED bulbs. The LEDs will last twice as long, so after 9 years, add $40 (a guess given inflation) for the fluorescents (based on ~6hr/day of use).

The LEDs use 10W less (60W less total) than the fluorescents. Based on the average $0.30/KWH that electricity costs me (actual cost, including taxes, etc.) the LEDs save 5.5 cents/hr and it will take about 5900 hours (2.7yrs at 6hr/day) to make up the $323 extra that the LEDs cost initially. By the time the fluorescents need replacing, they will have cost ~$800 more.

Hmmm... that switch makes sense to do.


I design and build led lighting strips that eliminate the need for fixture replacement. Our strips can be any length you require. A one foot section equals 800 lumens. A typical 8 foot tube produces about 3200-3800 lumens. A fixture with 2-8 foot tubes will require about 6500 lumens. Total cost to do this project would be $150. This would include the 24vdc power supply to power the strip, and a 3 year warranty.

we use a patented new technology that doesn't use a heat sink…so they last longer, are brighter, and there is zero green in the color. We also have a video on-line to help with installation… plus I'm here anytime for questions. We're a division of Bardwell & McAlister Lighting…in the movie lighting business since 1926…but just now are taking this new technology to the commercial market. We're mid-priced…and fully repairable (if EVER needed) in Sun Valley, California. So they are more of an investment than a throw-away lamp.
