Advantages of LED flood lights:

• Same form factor as a standard flood lamps• They draw almost no current, < .03 A.  Won’t register on Watts Up meter! • LED floods I bought rated at 110 VOLT, 0.025 AMPS.• They don’t heat up at all.  A half hour later they are still cool to the touch• Conventional flood lamps will burn your hand• Much longer life than incandescent bulbs• LED flood lamps do not flicker• LED flood lamp has 50-70 LEDs. If one burns out, the others will stay lit• No paint to wear off glass, the LED is the color.  They look clear, but when energized, will shine in their intended color

Disadvantages of conventional floodlights:

• Waste lots of power, 100W, gulp from .9A to over 1 amp!• They get real hot, you can seriously burn yourself• Colored floodlights are painted on and wear off quickly• Once colored paint wears down, you get hot whitish spots in the colored light

LED Flood lamps are expensive in 2007 pricing:

Blue LED floods are $13.60 eachGreen LED floods are $16.25 eachRed LED floods are $10.30White LED floods are $30!

Conventional flood lamps are cheap:

Standard colored flood light from Home Depot is $4.

A Tale Of 2 Cities:  2 flood lamp types I compared for this test:

1)  Sylvania PAR38 size, 100 W bulbs, blue and green, from Home Depot

2)  50 LED PAR30 size 3 7/8" wide MEDIUM BASE 35 DEGREE BLUE FLOOD lamp (3000-5000MCD) from Action Lighting.

How they were tested, blue lights first:I tested them side by side aimed at my dual front doors, one aimed at each door.  You can see conventional flood is on the left. LED flood lamp is on right.

Pattern from conventional lamp on left door has a hot spot in middle. Photo does not show how white the hot spot actually is on this year old faded lamp.  On right door see how the LED lamp has covered it evenly with a beautiful blue shade, similar to the “better part of the incandescent lamp’s blue color”.

Blue LED flood lamp by itself, aimed at right front door.  Beautiful and even blue color looks great.

Same phenomenon, worn down colors on the Sylvania green flood lamp leave a whitish hot spot in the middle.  The green LED is much more evenly lit across the right door than the conventional Sylvania lamp on the left door.

One blue LED lamp can light up half the front of the house if it’s not competing with a lot of other light.

White Flood Lights: Larger PAR38 size with 70 LEDs Cost in 2007 was $114 for a case of 4 lamps, almost $30 each.

2 new LED floods above on my garage door with pure white light.  We will use 3 of them to fill in the dark spot on the garage door. The light is pure white like snow.  The white LED floods appear to be dimmer so buy the largest floods.
