    LEDs are quickly becoming the way to go as color properties have improved dramatically and cost are rapidly declining. If you are considering installing dimming flourescent I have one recommendation - don't! Over thirty years in the business and flourescent dimming has been and still is a big problem and a headache. LED light sources approved for dimming are the way to go. We are using LED fixtures for interior and exterior lighting applications with much success. Yes, they cost a little more depending on the type and quality but the life is much greater, control is much easier and the energy usage is much, much lower.

    I agree with you that LED comes with brighter illumination, but most importantly, it uses lesser power!

    Since my last post, we've begun installing several of these units, with very little problem, at a reasonable cost, & the Customers being very satisfied.

    Ive been switching over fixtures to direct wire 4ft T8 bulbs. So far out of the 200 bulbs Ive had one failure. The price on led fixtures is falling so fast its ridiculous. I had planned on replacing bulbs in some recessed cfl fixtures with LED bulbs, but now the price of replacement fixtures has dropped below the cost of the bulbs. The cost of the bulbs was already below the cost of two cfls and a ballast. Plans also include 30 400 watt parking lot lights.

    I'm wondering what Affect the "Tariffs" will have on Availability & Pricing Billi?

    We had office workers complaining about the LEDs being too bright. It would have cost a small fortune to put the light switches in with the 0 to 10 dimmer and new wiring in the walls. Electricians put prewired ambient light switches in the ceiling aimed at the windows, and set the light high limit. This saved even more on lighting.

    I've installed hundreds of the direct wire 4' T8 LED's and they are quick to install, run very cool, as in reducing building loads, and have gotten several nice rebates from the power company to do so.

    One thing not often mentioned is the power saved by reducing the A/C loads. It is big. Also replacement costs.. Fluorescent bulbs last about a year in 24/7 service. Cuts man hours in maintenance. 5 year warranty too.

    Anyone have thoughts on recessed LED retrofits. Ive got over 100 tecessed CFL fixtures which are now 15 years old and ballasts are beginning to fail. Ive seen some plug in LEDs ($15 ea x2 per fixture) , (I prefer ballast bypass) and there are several types of Recessed LED fixtures with a very wide range of costs. ($30-$150) Of course its 277 which makes everything harder and more expensive. The one Im looking st right now is a lithonia fixture that just pops in the hole. Its just barely recessed and has a translucent cover unlike the open fixtures we have now. Any thoughts?

    Shallow recessed retrofit LED have a glare issue. Have tried a bunch, but I did find one that is dedicated LED trim for a LED "old work" can that works well for me. Deep recess on lamp. Black ribbed trim. Disappears on a huge ceiling, yet does a better job of illuminating the floor evenly. Something the CFL's do not do well. We are in the process of replacing all of the CFL's with these. Ours are 120VAC, but I believe that they are multi-volt.

    Do you bypass the original Ballast , and direct wire them to 120v ?

    I installed LED lights in a pastry cooler, they added enough heat to warm the cooler 5-10 degrees. The unit thermostat was in the top as well as the lights, now the cooler will not shut off while lights are on! There is no circulating fan in the unit!

    Did the Cooler have lights in it before? It just doesn't sound right that the LED's are overheating the cooler, as they run cooler than any other lights.

    We did a couple of those jobs in the winter... dozens of 4 bulb troffers on each job...
    We trashed the ballasts and direct wired... the local supply house had a kit with new 'tombstones' set up for one end power (other end was just to hold the bulb in place). The kit was something in the $5.95 each area if I remember (could have gone up since then).
    Anyhow... get rid of the ballast, direct wire, and use direct wire bulbs... works GREAT!
    And the bulbs we used... are 3500K temperature and have a 50,000 hour warranty.
