Amazon/GetInLight 4" Disk LED 3000°K, 550 lumens, 9 watts

After some difficulty, I have found much happiness with the start of a new family of disk LED lights, sold exclusively at Amazon . The discovery follows finding that recently-favored lights via importer Cost Less Lighting , are discontinued with no replacement offered. 

This is a really-pretty light suited to 4" can light retrofits and to direct mounting on any ceiling junction box. 
With circuits on board the light engine, the light is directly powered by line 120 vac. This will mount with ease on a small 3 1/2" ceiling box, mounting screw pitch 2.75", even if the box is well-populated with wires.

Beware though if you have a usual 4" junction box with inch-wider screw pitch. Beware too with any can or junction box open to space inhabited by bugs. The five openings of the back side glow brightly and WILL attract bugs madly seeking celestial navigation. Where an LED light can be maintenance-free forever, it will be quite a shame if one must climb up to twist off and clean the lens. 

The bug problem will be huge and certain where these lights are used  to improve upon architectural lighting with burned-out halogen bulbs. That is, if an installer is unaware of the bug-litter propensity. Where the GetInLight is cartridge-loaded into a 4" can, all bug-entry paths can be taped over.

My adventure with the photo at left is detailed here . My solution for architectural lighting has been 4" Glimpse, now impossible to find. Bug paths of the 4" Glimpse can readily be taped-over under-the-lens, whether installation is to a junction box or to a can.

Here the face cavities for screw mounting are readily taped over. The three irregular lens-attachment keyways can not be taped over in junction box mounting.. 

Here is a photo of the light almost-fully installed, not yet with the lens applied. This is in the overhead of a closet, working awkwardly in darkness. Notes on the photo detail missing items in the package, where I was willing to cope, spending a full day in pursuit of needed hardware. By my investment in making things work, then, I hope to work with Amazon to not frustrate the usual buyer

Where I install lights on RACO 175 steel boxes air tight and bug proof, and want lights of about 500 lumens as replacement of 100 watt incandescent in closets, hallways and bath/ shower overhead, I will have much interest in the 4" GetInLight, perhaps identified by its UPC, X000ZCIY39.

Here summarize some of the package numbers:
550 lumens for 9 watts is efficacy 61 lumens per watt.

Diodes are 3 mm dia., qty 33. There are 25 in an outer circle, and 8 at an inner circle, 57 mm array dia.

Diode area is 233 mm2. Diode luminance is 2.36 lumens per mm2.

Array area is 2552 mm2. Array luminance is 0.216 lumens per mm2.

I believe diode and array luminance are important competitive measures of a light, and that those glare characteristics of 4" GetInLight, are excellent.

At 4/1/2017, add observation that GetInLight 4" lights must be installed with their provided quite-thick foam gaskets. Installation without gaskets was tried with thought there might be a visibly tighter fit against the ceiling. Without the gasket, the lens keys interfere with the mounting plate. Without spacing created by the gasket, the lens does not fully engage, and it is very likely you will have difficulty rotating the lens to detach the light.

See one of the three pinched lens keys just inboard of the four slots at 3.5" pitch of junction box screws.

See a dark luminaire-to-ceiling interface, not reduced by absence of the gasket.

The gasket may be pulled over the dangling luminaire.

Better, pull the gasket onto the luminaire without release of mounting screws.

In June, 2018, I received my first order filled with an improved light, on the box labeled "2nd Generation." 

Appearance is visibly improved. A taller rim ensures that box mounting screws won't interfere with seating of the rim against the ceiling. A rounding of the top edge of the rim in first generation design produced the appearance of a gap, even if round-head screws didn't prevent rim to ceiling contact. 

The 2nd generation castings have key ways for much easier screw engagement.

The 2nd Generation has the mounting bracket I have wanted, in the box. At photo left here, show a simpler bracket adjusting to 2 3/4" luminaire hole pitch, that is shipped from a Nevada Inlight warehouse upon request via Amazon, if you receive a first generation luminaire. The simpler bracket is a fully acceptable offering.

Here see readiness to mount a first generation 4" GetInLight to a typical ceiling box with 3 1/2" mounting screw pitch. Accept the simpler bracket. Try the luminaire right out of the box, including the gasket. This ceiling box is in a test stand, and we are looking downward. The ready luminaire can be at rest in the photo.

Here see the first-generation luminaire installed with gasket. Everything does work. The manufacturer and shipper are giving good service via Amazon. Beyond June, 2018, buyers via Amazon may expect the yet-happier experience of 2nd Generation lluminaires.

In a job just completed, I have introduced a customer to the beauty and energy efficiency of LED downlighting at nearly the 500 lumens 3000°K brightness-not-glaring, that I think we should desire overhead in hallways, closets and bathrooms. I installed two of my inventory of first generation 4" GetInLight, and five of the happily-discovered 2nd Generation. In the hallway lath and plaster ceiling, I resisted the difficulty and structural damage of cutting in junction boxes for 2nd Generation luminaires. I could find joists for 1 5/8" deck screws capturing the mounting brackets. Drill a wiring hole 7/8" diameter that accepts push-up of the 18 ga 2-wire power lead and taped-over smallest-available twist connectors. Insulation overhead has a 1 1/2" thick loose-fill mineral wool base that absorbs the pushed-up wires.

The 18 ga power leads are home runs to a post seen as site of a wiring junction box, suggested as a new product development to Cooper Lighting, in Georgia. Home-run lighting leads centrally collect their neutrals. For now, four-wire clusters are acceptably wire-nutted. The home owner knows what this is. If I can not acquire a proper panel, a well-preserved instruction notice will be in order.

How does my action to avoid junction boxes differ from the practice at a central luminaire in most rooms of this 1918 home? Don't cut the lath and plaster in a remodel where 1/4" drywall "fixed" cracked ceiling plaster. Install pan boxes 1/2" deep. Structure of the antique incandescent-bulb luminaires successfully engages the pan box and a mounting bracket. I don't believe my clustered wires out-in-the-open and understood, are in violation of electrical code. On the other hand, it is right that we challenge code, to evolve in acceptance of very-low-power LED lighting, including low voltage DC strings to panels with common AC to DC power converters and dimming, and even to panels purely direct current.
