In September 2018, I find these:
Online with no image yet, at $24.98 .
700 lumens at 9.7 watts, box claim on left side panel.
Online at $24.98 :
758 lumens at 9.63 watts. box claim at left side panel.
Find 4" Glimpse 3000°K 450 lumens at my comparison stand LHS. Install SMD4R6930WH 3000°K 700 lumens at stand RHS.
At full power. Find comparable color temperature, and the 700/450 brightness difference expected.
In place of the 4" Glimpse at stand LHS, swap in the big SMD6R6930WH 3000°K, 758 lumens.
The SMD4R6930WH at RHS and the SMD6R6930WH at LHS should not be distinguishable with a 758/700 brightness ratio. Do see a fuzzy shadow of the bigger light.
Bring in a Commercial Electric 74203 at stand LHS, swapping to replace the SMD6R6930WH. The 74203 from Home Depot were on sale recently at $8.99 half-price, and I bought a carton. From these I will install six this day 9/24, in my new kitchen ceiling. Learn what I can, to support this decision.
This comparison is very surprising and supportive of my plans for the day. The claimed-500 lumens light at LHS is brighter than the claimed-700 lumens light at RHS, and the 3000° color temperature comparison is excellent. I have been concerned the 74203 might be more-yellow than wished.
Here I question what view at my test stand is best for comparisons. Added room detail seems helpful.
Here is my as-built lighting plan. Does not include new discoveries at Lowe's stores.
With a mock-up, imagine ceiling cuts 3" diameter for the brackets and luminaire mounting of CE 74203 LED disk edge lights. I wished to find lights that demanded only minimal ceiling cuts, to pass wires. The newly-found lights from Lowe's would absolutely require 4" cuts.
In fact I needed to do one installation very much like this. A 1x4 bridge of drywall edges interfered with cut-in of a junction box. Cut a 3" hole in the drywall, on the hole center, before cutting a 2 1/4" thru-hole in the 1x4.
Now, is there really anything to be saved by making a smaller hole, if a sizable hole can't be avoided?I have developed the method with 3" holes, but it is simpler and more versatile to just cut in RACO 175 boxes now, as done here for light Position m.
Here is my attic completion of lights wiring, Box 2 in the diagram above, and some very efficient terminal strips. One terminal strip each for circuits 1. 2 and 3, and a fourth strip for neutral wires. My home-run leads of AC power to luminaire positions is 18 ga. I hope to demonstrate that 11 watt luminaires should no longer be fed with 14 ga romex leads. The home runs sometimes miss opportunity of daisy chains, but bring flexibility of switched light groups, and are more error-free. I have no progress toward wiring of lights as DC, but think I bring fresh experience to a methods table. I will pretty up all of this wiring before moving on to other work outside my home.
I have mixed feelings about not carrying ground wires to the luminaires. The green wires here serve no purpose, and I think 2-wire 18 ga wiring Black/White, is better. Manufacturers do not understand the need of luminaire grounding, often making installations more difficult and unreliable. Can we just eliminate ground wires?
Pursue that decision to leave green wires not-connected. Here are the full contents of the Commercila Electric 74203 package. See a screw and a green wire in the bag.
Here are the installation instructions, the two sides of one piece of paper.
Intentions for the green wire and screw are evident in Instructions Step 3 at top of Instructions second page.
It is intended that ground from the circuit breaker be applied to the luminaire mount ring. What does this achieve? Just that if a bared power lead touches the ring, there will be trouble.
I think a principal purpose of a luminaire ground wire is to serve as an installation tether, and that is not done here.
