Q. Can't I just install a whole new fixture?
A. You can, but consider the following:
- Cost of the new fixture
- Lower wattage units available in LED - 2', 4', 8'
- Cost of the labor pulling out the old fixture and installing the new one - much more costly than
the plug & play LED retrofit units that are less than 1/2 the installation cost
- Disruption of any existing employees or tenants is much greater
- Higher cost of disposing of and the labor to dispose of the old fixtures
- Filling our landfills needlessly - think sustainable
- Easily half the cost of installing a new fixture
Q. Why can't I just install a new T8 bulb into an existing T12 fixture?
A. Fluorescent bulbs are driven, or lit up by the ballast that is in the fixture. A T12 ballast will not
match the new T8 bulb and will overdrive the bulb causing excessive heat and premature T8
lamp failure. A new T8 ballast will have to be installed prior to installation of the new T8 lamp.
Q. Can this LED unit be used in a 120v or 277v fixture?
A. Yes, the AEFDirectConnectLED unit is a universal LED tube.
Q. Would installing a new T8 ballast and new T8 lamp be easier than installing an LED
A. You would have to open up the ballast area, remove the existing ballast, dispose of the ballast,
and then install the new ballast and lamps. With the AEF DirectConnectLED units you would
open up the ballast area, clip the two wires coming into the fixture (which will disconnect the
existing ballast-which is not reused as in some LED tubes on the market), connect the wire whip
to the hot & neutral wires coming into the fixture and plug the other end of the whip into the
LED. You are now done and will NEVER have to get into the ballast area again because
the LED has a built in driver. Labor is reduced CONSIDERABLY going forward because you
never get into this ballast area again.
Q. If I don't need to replace my light fixture how do I save money?
A. The AEFDirectConnectLED unit can burn as low as 18 watts. Compare to burning T12’s at 34 watts or
40 watts or T8's at 32 watts + the wattage in the ballasts. If you de-lamp to 2 bulbs, which you
will be able to do with the AEF DirectConnectLED units because the lumens are so high 2360 lumens
compared to most LED units on the market that are only 100 watts per lumen or 1800 lumens.
If you de-lamp to 2 bulbs you can save over 70% in energy costs..
Q. Does the AEFDirectConnectLED unit give off enough lumens to de-lamp?
A Yes, the LED give off up to >133 lumens per watt
(most current LED's on the market are >100 lm/w)
18w at >131 lm/w = 2,360 lumens
22w at >124 lm/w = 2,730 lumens
22w HO at >151 lm/w = 3,624 lumens
Q. What, I don't need a ballast?
A. All old style heavy ballasts are not needed. The LED plug & play has its own built in driver
with a specially designed extruded heat sink aluminum housing that reduces internal heat.
Q. Can I save additional energy because the units do not give off as much heat as a
T8 -T12 or T5 lamp?
A. YES, that is correct. Our calculations will show how much your air conditioning costs can be
Q. What is the beam angle of the AEFDirectConnectLED Units?
A. 160 degrees .vs a typical 120 degrees. This allows a wider spread of light which also
helps to allow de-laming.
Q. Are the AEFDirectConnectLED units DLC approved so we can get rebates?
A. Yes. All of the DirectConnectLED units are DLC approved for rebates as a "retrofit kit"
.vs a "tube". In many areas, this will allow higher rebates. Check with your utility provider.
Q. How much do I save?
A. Your electrical light savings will be reduced between 30-70% (de-lamping would be 70%+).
(This will depend on what your existing lighting wattage is and what your new wattage will be)
Q. What is a typical return on investment?
A. The ROI (Return On Investment) averages about 12-24 months based on the U.S. average
current kWh costs. If light are burning 24/7, the ROI can be less than 12 months
Q. Do the AEFDirectConnectLED retrofits have a UL rating?
A. The LED's are ETL certified under UL standards
Q. Can I use these units in a vapor tight fixture?
Q. Do the LED units flicker and hum like our existing fluorescent lights?
A. No. They do not flicker or hum.
Q. Is it more cost effective for me to change out my old T12 Bulbs and Ballast to new T8 bulbs
and to a new ballast?
A. When adding up the product costs, installation costs (which could be more because of the length
of time it takes for installation and the cost for additional conversion "kits" that may be needed,
the disposal costs of the existing ballasts, the HVAC savings and the additional labor for replacing
old and broken lamp holders you will find that the plug & play LED units will show a lower ROI.

Q. Do you have an LED product that will replace a metal halide or HID unit?
A. Yes, our new LED high bay fixture uses our 24w HO units up to 158 lumens per watt.
Q. Will a 4-Lamp high bay fixture replace a 400w metal halide fixture?
A. Yes, the 4-Lamp LED high bay has 14,792 lumens
Q. How many fixture watts are the 4-Lamp LED high bays .vs a 400w metal halide?
A. The AEFDirectConnectLED 4-Lamp high bay is 96 fixture watts .vs 458 metal halide fixture watts.
Q. Do you have a 6-Lamp high bay?
A. Yes, the AEF 6-Lamp is 144 fixture watts with 22,188 lumens
Q. How long is the manufacturer's warranty for the LED?
A. Five Year manufacturer's warranty which is non-prorated - compare this to other 10 year warranties
that require a 10% failure rate before any warranty replacements are given.
Q. How long will the LED units last?
A. <50,000 life in a 120 degree fixture and <75,000 hours in a 77 degree fixture
Q. Can installing a better quality of light and more light increase productivity and decrease
A. Yes, it this has been proven to be fact and there are many studies and white papers on the
internet that discuss the percentages and the money that is saved annually by companies.
Q. Are other LED retrofit units in the marketplace less expensive?
A. You can always get a product "cheaper" but you have to look at the whole picture; installation,
energy savings, etc. However, if the T8 ballast is less expensive they might have a lower ballast
life. (drives the lamp at less lumens per watt)
This would then make sense that a ballast that is three times lower than the AEF LED units would
be less expensive. AEF can purchase these lower end LED's (that are not typically UL rated)
but have chosen to only sell the top of the line adapters. Many are not UL or DLC rated for the
AEF works with Fortune 50 companies who demand the best that is available.
The AEFDirectConnectLED units are competitively priced and since they give off more lumens per
watt you can de-lamp your fixtures which greatly improves the ROI.
Q. What is the US Department of Energy mandated phase out schedule forT12 ballasts?
April 1, 2005: Manufacturing of T12 ballasts prohibited
July 1, 2005: Sales of T12 ballast for use in new lighting fixtures prohibited
April 1, 2006: Sales of T12 lighting fixtures containing ballasts prohibited
July 1, 2010: Sales of replacement (MRO) T12 ballasts prohibited
July, 2014: Sales of most T12 lamps are prohibited
Q. What do the AEF DirectConnectLED units look like?
Q. Do these LED units energize the existing lamp holders and do you have to
replace the lamp holders?
A. No, the lamp holders are not used at all. The LED units magnetize to the top of
the fixtures. If needed, a hole is in the middle of the magnets allowing installation
of a self tapping screw. No additional kits or costs are involved.
Q. Is the existing troffer altered?
A. No the troffer is only being used to magnetize the unit to the top of it
Q. How long are these LED units?
A. 44 1/2" long from end to end - they fit easily between the existing lamp holders-even T5 troffers
and T5 high bays can be retrofitted
Q. Can you de-lamp?
A. Yes, since these give off up to 131 lumens per watt (which is the highest lumens per watt
of most any LED units on the market) and can easily be de-lamped
The HO DirectConnectLED is up to 158 lumens per watt
Q. Can you center them in the unit when you de-lamp
A. Yes, because of the magnets that are on the back of the LED units, you can position them
anywhere in the unit
Q. Can you put a screw in the magnet clip if you wanted to?
A. Yes, there is a hole in the center of the magnet that will enable you to use either the clip
with no magnet or our new clip blade that can be put anywhere on the unit and positioned
exactly where you want to attach it in the troffer.
Q. Can you connect units within a fixture without rewiring each of the units to the
incoming line voltage?
A. Yes, just wire the 3' power whip to the first unit and clip in the jumper whips from one unit
to the next
Q. Can you retrofit an existing T12 or T8 8' fluorescent fixture?
A. Yes, connect two 4' units using the 2" connector whip to make an 8'
Q. Can you de-lamp two 8' fluorescent fixtures?
A. Yes, because the AEFDirectConnectLED units have such a high lumen per watt package
Q. Can you daisy chain these when you have end to end fixtures?
A. Yes, use the jumper whips to connect the units up to 240' (277v) and only wire to
the incoming line voltage on the first unit. Simply magnetize the rest of the units to the fixtures
Q. How does the AEF LED Unit get its power?
A. The 3' power whip wires directly to the incoming line voltage: hot & neutral
which bypasses the existing ballast. Then simply plug it into the LED unit and it lights up.
