Has anyone else tried LED light bulbs for over the workbench?
I have Great Value (WM) daylight (5000k) 950 lumen, 8.5 watt bulbs in parabolic clamp lights, and they are the best lighting I have ever used, other than sunlight. They are approximately equivalent to 68 watts incandescent, but seem much brighter.

I had all my 4 foot drop ceiling light replaced with the led bulbs 3 bulbs instead of 4 these bulbs are wired straight no ballast seems they put off more clean light i like them. i will be putting them in my shop too.
-
Could you post a photo of the installation, please? ???
-
you use the same fixtures the florescent bulbs are in just rewire it the instructions come with bulbs on how to do the rewire.
-
All well and good, but what does the fixture LOOK like?

I ordered 1 of these for our laundry room but paid less than $130 vs. the $180 they have it listed for now. It replaced a single clear 60w incandescent (800 lumens?) and now I get a bright (4100 lumen) crisp (4000K) light which makes a world of difference. With the cost of LED lighting dropping dramatically, I have no clue why the substantial price hike in only 5 months.

Good info. I bought some cheap Flour. fixtures yrs ago and they promptly went out one-by-one (ballasts). Not worth fixing, but if I can convert them... ??? ;D

If they turn on cold that would be a huge plus. In my garage the florescent bulbs have OSHA sleeves on them not because there is a significant risk of breaking, but because the sleeve holds heat so in the winter the bulbs eventually light up fully. This takes a couple minutes still, but is a real improvement over not using the plastic sleeves.

Phil I understand they turn on cold. The light they put if brighter then florescent bulbs.

This is only the tubes (bulbs). The pin bases need to be rewired or conversion bases installed. Conversion bases have a black and a white wire going to each base. The LED tubes feed only from one end. The other end only holds the tube in place. Only the fixture housing is reused.

Is the idea to just get the bulbs then rewire the existing fixture to save $130. You're saying just bypass the ballast then juice the bulb from one end?

...DIFFERENT MODEL. THE MODEL #LBL4 (4000K) IS $129.00 .THE (3500K) , YOUR LINK, IS THE MORE EXPENSIVE MODEL.

The color of light, rather than its brightness, is what creates an eye saving and workplace friendly environment. The color temperature of light is a measure of the hue (red, blue etc.) of a light source.
The best light to view colors at the their true hue is a clear day during noon. 'Noontime sun and sky' has a temperature of 5500K and has a blue hue. Artist studios are ideally facing north to catch the blue north light coming from the ice crystal filled Arctic sky. John's bulb @ 5000K is right on.
The other benefit to color correct light is one's mood. The winter doldrums (Seasonal Affective Disorder!) a situation which has something to do with the shorter days of winter and the lack of exposure to sunlight (lack of vitamin D?), can be treated by spending time in front of a bank of color corrected lights (Light Therapy!).
I continually remind my wife I'm such a cheery guy because I'm under corrected lighting all year long building my planes!
