5.0 out of 5 stars Excellent 500w flood fixture design..
Lithonia 500Q Flood Light

The short answer is, this Lithonia is the best designed 500 watt halogen fixture on the market.

Here's the long answer...

Halogen 500 flood lamp fixtures come in three basic designs:

1.0 out of 5 stars Lousy Experience
I see that all the previous reviews give this light five stars.

I bought eight of them over a year ago to install on the exterior walls of two apartment buildings. I like the light they throw. I like that I can choose among different strength bulbs so that I can use higher intensity where I think I need it, and save electricity where I don't...

5.0 out of 5 stars Excellent 500w flood fixture design.., January 7, 2011
This review is from: Lithonia OFL 300/500Q 120 LP BZ M6 Light Visor Flood Light with One 300-Watt and One 500-Watt Quartz Halogen Double-Ended Lamps (Tools & Home Improvement)
Lithonia 500Q Flood Light

The short answer is, this Lithonia is the best designed 500 watt halogen fixture on the market.

Here's the long answer...

Halogen 500 flood lamp fixtures come in three basic designs:

Design Group 1

RAB Quartz Flood 500 watts
Designers Edge L-50BR 500-Watt Halogen Floodlight
Heath Zenith SL-5505-BZ 500 Watt Halogen Floodlight
LIGHT FLD HAL QZ 500W WT [Misc.]
Ace Outdoor Halogen Quartz Floodlight (AWQ500)
Cooper Lighting GP-500-WL 500W Halogen Floodlight
Cooper Lighting WQ500 500W
Cooper Lighting/Regent Light 500W Fld Light

All of these lamps have a fatal design flaw, in that bulb replacement is terrible. To replace a bulb, you have to slide two clips holding the unframed glass lens out of the way and carefully remove it without cutting yourself. (The Ace and Cooper models require unloosening two screws to slide the glass out.) Typically, the glass lens will be stuck to the rubber gasket and has to be pried off - which is risky, since prying could crack the glass, plus the glass could be dropped. Imagine doing that high up on ladder, where you'll need find a place to keep the glass lens while replacing the old bulb!

Design Group 2

Hubbell Q500 flood lamp
Cooper Lighting QL-500-WL 500W Industrial Grade Halogen Floodlight

These lamps are a much better design the those in Group 1, because the glass lens is fully enclosed in an access door. Bulb replacement is much easier and it's highly unlikely that you'll cut yourself on the glass or drop it. I.e., remove a single screw and the door swivels down for easy bulb access. However, since you'll be leaning out a window or on a ladder to get to the lamp, the best designs require no tools to re-lamp.

Design Group 3

Lithonia 500Q flood light.
Designers Edge L-31BR 500-Watt Halogen Floodlight
Globe 60500 Supra Lite 500-Watt Outdoor Halogen Flood Light

Similar to Group 2, except that bulb changes are completely tool-less and easy. Simply release a stainless steel clip and lower the hinged door for full, safe, access to the bulb.

The Designers Edge L-31BR uses a crinkled glass, which blocks some of the light.

The Globe model doesn't include a mounting bracket, which is needed to mount the lamp - so unless you have an outdoor lamp-holder bracket of the same color on hand, avoid this one.

Summary:

The Lithonia 500 watt flood light is an excellent design. Highly recommended.

Bulb Replacement:

It's not uncommon for aging outdoor halogen flood bulb-holder contacts to corrode, killing your lamp. Once that happens, the lamp itself will need replacement. To curtail corrosion on a new lamp, apply a tiny dab of electrical contact grease on all halogen flood bulb ends. Dielectric grease seems to work just as well as an anti-corrosion measure.

This review is from: Lithonia OFL 300/500Q 120 LP BZ M6 Light Visor Flood Light with One 300-Watt and One 500-Watt Quartz Halogen Double-Ended Lamps (Tools & Home Improvement)
Thanks to Victor's previous review I went with this fixture to replace blown out lamp I had replaced just 6 months ago. The simple clip to release the glass for bulb change is a design worth its weight in gold. I have dropped and broken glass on a previous install and to do a simple bulb change was a 3 times up 3 times down ladder marathon. Quality of this fixture is noted improvement over the 3 others I have used. Also take note of Victors tip on dialectic grease.

I installed this about 30' in the air on a tree next to my son's basketball hoop in the driveway. With the 500W bulb the whole court area is illuminated.

The construction is sturdy and the flip-up hinged cover makes bulb install/replace a snap while standing on a ladder.

1.0 out of 5 stars Lousy Experience, March 19, 2013

This review is from: Lithonia OFL 300/500Q 120 LP BZ M6 Light Visor Flood Light with One 300-Watt and One 500-Watt Quartz Halogen Double-Ended Lamps (Tools & Home Improvement)
I see that all the previous reviews give this light five stars.

I bought eight of them over a year ago to install on the exterior walls of two apartment buildings. I like the light they throw. I like that I can choose among different strength bulbs so that I can use higher intensity where I think I need it, and save electricity where I don't.

However, I've had to change bulbs far too frequently. I would estimate that the best I get out of a bulb is six months. Sometimes I only get a few weeks. My handyman is very careful when replacing them, going so far as to wear gloves bought specially for the purpose of installing bulbs without getting any of his body oil on the bulb.

After about a year, one of the lights failed, with scorching on the two posts that the bulb connects to. I replaced it with another matching light. A few months later, the same thing happened to two more lights. Today, when another one blew, I decided I'm not throwing away any more money on these things.

I've been using name brand bulbs. Wattage ranging from 200 - 500. As I said, very careful with bulb replacement.

Oh, another thing: I've also replaced three photo-sensors (purchased at Home Depot) when the light sensors failed.

I can't explain the contrast between the other reviews and mine.

4.0 out of 5 stars Great Quality, January 26, 2014

This review is from: Lithonia OFL 300/500Q 120 LP BZ M6 Light Visor Flood Light with One 300-Watt and One 500-Watt Quartz Halogen Double-Ended Lamps (Tools & Home Improvement)
Good design, Easy Install, Nice weather seal and Clip. Hope the screws are good Stainless Steel so they don't rust.
Only gave it four stars due to concern of bulb in that it is small and fragile ( worried about breakage and life).
Installed 300 watt bulb for parking lot, also installed bulb using gloves and dielectric grease on the contacts only. Installed unit on Brick wall at Peak of roof with no overhang. So, it gets full elements, wind, rain, sleet, sun and snow.
300 Watt bulb so far works reasonably well to illuminate 30 X 50 ' area. Timed for cycle of Dusk to 11:00 PM, then 4:00 AM to Dawn. This bulb should last 2-3,000 hours so I should get about 1 year out of it.

This came well packaged, was easy to install, and works great. I bought it to replace a similar unit and it hasn't let me down yet.

This is super bright. It was easy to install and aim. We need it to shine light on a street 100' away from the house. It works.

I bought this to replace a similar fixture I had for 10 years. The ceramic connectors had deteriorated over time causing the halogen bulbs to emit very little light. This fixture has been on for less than two months and the connectors are shot. I tried changing bulbs, but to no avail.

Nice unit, well made, easy to install, and comes with two different wattage bulbs. Changing the bulb is a snap since it has a hinged glass cover and a snap closure. No screws to remove. Finish is really good, too.
