LED Shop Lighting

[atlr]

Pixi Lighting just released a 1'x4' fixture with a 4000 K color temperature that operates at 120 V.  Illumination comes from LEDs edge-lighting the face of the luminaire.  I tried their 2700 K which was too warm for my taste. Until now, the only 4000 K model they offered required 240 V.

As far as I know, these are only available from Home Depot's web site in the USA.

I will post some pictures when I try one.

Look forward to hear how it lights up your shop area .

Thank you for posting this.  I was thinking or adding a bunch of lights. 

These look pretty slick but dont put out as much lights compared to T5 fluorescent. 4200 lumens for these LEDs in a 12 x 48 package, whereas 2  T8 fluorescents in a similar package will put out at least 5500 lumens. And T5 put out almost 5000 lumens per bulb.

Definitely impressed by the LEDs thickness of 0.5 inches.

i retro fitted led to a strip light .no ballast just wire 120volt to socket on one side of the fixture.but wow they aren't cheep.i think $75 a 4 foot lamp

seesmart is the company

I'm in the process of changing out the 4' flourescents in my shop with in ceiling can lights and regular LED warm white bulbs - the cans are about $9 each and 75W Cree LEDs have been as low as $5.50 here in Seattle.  My ceiling is exposed so this isn't a problem.  Great light, less electricity and no CFL delay.  Not sure if those LED strips are worth the extra money.

What is the spacing on the can lights?  I was considering doing can lights but am concerned whether or not it will be enough light.

Been kicking around replacing all of my T8 daylight fluorescent with can lights as well. Tired of hitting the shoplight frames when moving stuff. I am concerned that I will get enough light as well. I have a row of 6 double bulb fixtures in back half and same in front half. Going to start replacing pegboard with slat walls today. Hopefully someone with lighting knowledge can provide insight before I start rewiring. Hate electrical work so keep putting off trying a few cans

I use 1 x 4 fixtures with 4 T8 bulbs each, and I plan to have 9 of them in my garage.  That's 76,500 lumens.  To get the same amount of lumens, I would need to spend $3400 for LED!  I will spend $600 total for my current plan.  I would really like to have LED, but for my garage, it's still too expensive.

FWIW, I do have the LED can lights in my kitchen, and was a little easier to accept that cost, since I have far less bulbs, and I was going from halogen to LED.

I worked for an LED lighting company a couple years ago, and our cost then for a 4 foot T8 LED tube was over $30. To retrofit my shop would have been over $1000, buying them at cost.  It is going to be a LONG time, if ever, before I can go completely LED. What I have done is use a few LED spotlights in clamp-on reflector style work lights for increased lighting over certain tools, such as my lathe.

Good point. My old drill press can accept a 40 watt incandescent lamp. Putting a 40 watt LED in there would more than quadruple the light.

Vijay, consider that the lumens value of a bulb(lamp) describes total light flow(flux) from a source.  A T5 emits 5000 lumens from its entire  cylindrical surface area.  A light fixture (luminaire) redirects some of that  light toward a surface. The light(illuminance) reaching a work surface  is a function of the angle and distance from a light fixture(luminaire).

I think the Pixi luminaire emits more flux perpindicular to its surface than the  fluorescent shop lights I have.  Take a look at the  Pixi illuminance chart in its spec sheet ; around 1700 lux at the point 6 feet below the center of the luminaire.  This might be too bright.  (Here is one source of recommended light levels for various tasks.  http://www.engineeringtoolbox.com/light-level-rooms-d_708.html )

Qualities that the Pixi 1x4 lacks is having partial indirect light (ambient light is a good thing) and glare reduction (parabolic reflector grids are one way to reduce glare ).

aargh, I did not read the luminance chart correctly.  Center luminance is about 425 lux at 2 m below the fixture which is not very bright.

You would be looking at more than 10 times the light [scared] a 3 or at most 5 watt led would be better.
