I started a thread about <lots of good info snipped>
I hope you find this as informative as I did.

Do you have any measurement of light before and after?
for example:

<snip>
In my shops in Mississippi:
With one of the Feit lights about a foot below my 12' ceiling I measured 450 Lux at waist level.
With one of my old 8 foot tube dual 60 watt bulb fluorescent fixtures about 6 inches below the ceiling I measured 230 Lux at waist level.
With one of the tubes in my "deballasted" fixture about 6 inches below the ceiling I measured 420 Lux at waist level.
With TWO of the tubes in my "deballasted" fixture about 6 inches below the ceiling I measured 700 Lux at waist level.

There are several measuring apps for smartphones.

I started a thread about my Led shop lights and discovered this one so I'm copying it here to add to the info.
I've been replacing the CFL's in my home with LED's since summer and it's now time to upgrade my shop lights.
My shop is 40x60 with 12x12 doors and is poorly lighted.
The main lighting consists of (6) 8ft (2x60w) T12 fixtures approximately 10 off the floor.
Around my lift I have four 8ft fixtures with three T8 32w 6500k (Daylight) lamps each.
The T8's are new and provide quality light and are not going to be changed out yet.
The main is lighting is not performing and one the reasons is that they are turned on & off frequently and are started cold because the shop is heated only when I use it.
I replaced the T12's with 48w 6500k 6000 lumen LED's.
The LED's are direct wired for 120v so I just disconnected the ballast and rewired them leaving the ballast in place.
The improvement was huge! The new lights are much brighter and allow me see detail much better.
The previously dark corners of the shop are now nicely illuminated.
I have a Killawatt meter so I measured the power consumption of the oil & new lights which I found very interesting.

The old F96T12 60w lamp data; VA 143 W92 A1.16 PF.65 X's 12 lights = 13.92A
Total power consumed = 1.716kw x 8hr = 13.72kw per day.

New LED 48w 6500K 6000Lumen; VA 96 W92 A.79 PF.96 X's 12 lights = 9.48A
Total power consumed = 1.152kw x 8hr = 9.216kw per day.

Yesterday I bought two Phillips 4 direct fit T8 5000k LED's at Home Depot for $10 and installed them for comparison against 2 F32T8 Daylight lamps.
These LEDs are direct fit and use the original ballast for power and are surprisingly less efficient than the T8's.
F32 T8 LAMPS VA 82 W63 A.68 PF.76 x12 LIGHTS = 8.16A
LED VA 96 W93 A.79 PF.95 X12 LIGHTS = 9.48A
Researching my lights it appears (to me) that UL listed lights are direct replacements for the CFL tube lights and use the existing ballast.
My lights are not UL listed and require removal of the ballast before installation. I chose non UL listed because I wanted to minimize electrical consumption.
If my assumption's are wrong please correct me.
I hope you find this as informative as I did.

Let me sum up what I think you said, and please correct me if I made some wrong assumptions in your presentation.

I think you are saying that changing out the old 8 fluorescent tubes with your new LED replacement tubes AND wiring around the ballasts is well worth doing from a money saved and light intensity gained prospective. BUT replacing your 4 foot T8 tubes with the phillips direct replacement LED tubes and re-using the old existing ballast is a money loser, but you didn't mention if these were brighter or not than the original T8 tubes.

Am I correct?

I replaced my Mom's 4 - 4' florescent kitchen lights with Costco's 4' LED. They work great!!!

Wished that had been going when I ordered mine about two weeks ago!

Costco customer service is usually terrific about crediting you back for recent purchases that have had a subsequent promotion/sale.

This is a really good price but, I think that the 4100 K color temperature will be a bit too "yellow" for shop lights?

Any feedback from someone who installed some of them?



Light on left is Sam's Club which is 5000K and light on left is 3000K.

Big difference?

Nope! I put Costco 6 qty of 4ft fixtures (2 bulbs each) with 4100K in my garage/shop and they are a nice clean white. Not yellow at all.
