Im interested myself....only need 20 bulbs for mine.....been looking every where on the net. Or maybe highbay style LEDs....shop has 12 ft ceilingAny recommendations for changing double bulb 4" T12 fluorescent bulbs to LED? HD has dozens, Amazon has 100's and Fleabay has 1,000's.
The shop has about 40 fixtures all are double bulb 4'. So I need about 80 bulbs.
3yrs now very happy $6.50 each
You can get LED replacements. It's very simple, and extremely affordable.
You simply bypass the ballast, and run 120V directly to the bulbs.
That being said...
Some replacement bulbs are single end powered... and some are double end powered.
Single End: Only uses one mount (tombstone) to power the light. The white wire goes to one prong on the mount, the black wire goes to the other prong. These are more of a pain, as you usually need replacement tombstones to wire them up like this.
Double End: With these bulbs, the white wire goes to one end of the bulb, and the black wire goes to the other end of the bulb. These are a lot easier to wire, as you just splice into the existing wires. No need to try and hook up both 120V wires to only one tombstone.
I've used the double end powered ones, and have been extremely happy.
As for color. 5k gives a nice, white light. 6k starts to get a little bit of blue, but is not bad. Above 6k is too much blue in my opinion.
Bulbs can be clear or frosted. Bulbs with clear covers... you can see each individual LED. If the bulbs are going to be in your direct frame of view, you do not want the clear covers. Frosted covers are easier on the eyes, and still very bright. I recommend these in most situations.
I agree back in January I bought the retrofit kits and converted 20 8ft flourecent fixtures in my shop to 4 ft 5000K frosted direct wire. Green LED zone is where I bought the bulbs and kits as they were on sale.I'm not saying those aren't quality bulbs but you can certainly get cheaper. I bought mine on ebay for right around $3.60 per tube, depending on how many you buy. That's the price for 50 and includes free shipping. It's been a couple years now and no problems with them so far.
I agree with all this. Ballast bypass and double end power is definitely the way to go. I have 6.5k color ones all through the garage and like the bright white light they provide. Some people like a "warmer" more yellow color for the house but I like the whiter ones even there.
I have mostly frosted but do have a few clear ones in the basement. I don't notice any difference in the brightness between the two.
I have a shitload of fixtures between the house, garage and shop and most of them have now been converted. After you do a couple you get the knack and can knock out rewiring a fixture in no time.
Well worth it. The garage lights fire right up no matter how cold it is and provide a nice bright light for less than half the electricity usage.
If you have the cheap 4 ft fixtures that are pretty much an 'all in one' unit... it's usually easier to simply replace the whole fixture with a similar LED unit. These can be bought cheap... for around $20 or so.Just pulled one of mine down and they have some type of electronic component in each socket end. Nothing like the old ones I was used to seeing with the big ballast in the center.
I bought a few at home depot for 20bucks for a 4 pack of 5000k direct fit .put them in random spots to compare to my high efficiency flourescents.They are def brighter and whiter and so far no problems.Will continue to swap them out as needed till all 80 are switched over to led.Does not seem to be neccesary to rewire the fixtures to me.
Worried about ballasts? Not me, They are already 40+ years old now, back when shit lasted.
