![]() ![]() I'm sure CREE will find a way to fix this. This alone renders the T67 unacceptable in its initial form. The direct observation is with two of the most-useful dimmers, Cooper Wiring Devices D106P, and Lutron C-L Dimmer, CTL-153PDH. There is a loud hum, from the T67 luminaire, when connected to any dimmer. If T91 is B6.7, and the incandescent is B4, the T91 should be judged 67% brighter here.Īt, I add a very important forgotten observation. ![]() Here is the comparison of T67 and T91 brightness and color: Whatever the flaws or naivete of my effort, it is better than accepting package lumens claims as statement of relative ability to produce useful illumination. The study is subjective, but I think it is consistent in comparisons, especially where two lights have the same color temperature. I don't think brown tones are reflected from the OSB divider, as colors don't change much when a white towel is draped over the divider. The drywall has a satin finish application of very bright white paint, and yet photos capture general brown tones. I now project lights indoors against a 4' square of drywall. Google Docs does a poor job of rendering. To view this, please download, and study on your own computer. ![]() Here in Google Docs is my latest effort, now including T67 lights. I continue to develop my own experiments in comparative rating of brightness of LEDs and other light forms. Home Depot and CREE have put good thought into bug-proof simplified mounting. My preference is for RACO 175 steel boxes, with only the 3 1/2" oc screw positions, which work fine. Boxes knocked out of service are the good family of fiberglass boxes, by Allied Moulding. I hope they will reconsider, and will offer instead a 3000°K product, or a hybrid where LED phosphors are of a sampling of colors, For now the block over the diodes will interfere with some found lighting junction boxes, where most boxes unfortunately, and perhaps needlessly, include posts for 2 3/4" oc light fixtures. Home Depot is again offering only one color temperature, this time 2700°K. In this, again exclude beam focusing in a cone. "LED downlight" may gain acceptance as the alternative for best-efficiency luminaires. #Home depot ultra light disk led sylvania licenseThe phrase is securely related to license plate illumination. And, editing this post at, admit giving up on "LED plate light" as wordcraft. Let us reserve the label plate LED, for presentation with negligible diffuser angle. This post will present portions of a Picasa Web Albums review of Home Depot's new T67 LED Disk Light, Manufactured by CREE, and packaged as Commercial Electric. ("New" was December, 2012, very long ago in the evolution of LED lighting.) Manufacturers and their big-box outlets which don't respond as LED technology rapidly advances, deserve no sales. The Sylvania 70732, very nicely priced at Lowe's, has a major improvement in July 2014, now behaving as perfectly on a dimmer as the Nicor DLS. At, add this: Another good option is Sylvania 70732 . Nicor DLS behaves perfectly on any dimmer and has other advantages. Instead buy Nicor DLS10 in online purchase. A reporter is needed when products are discontinued without explanation, as with wonderful and not-glaring Nicor DLS10. For T67, or for T47, n othing on new packaging or at, informs the buyer of changes made. Obligation to be a responsible observer is negated by manufacturer action to offer improvements, and sometimes a degraded product, with no announcement. I ponder my role as a self-appointed reporter. I measure identical 11 watts draw for T67 and T47, as it should be, and in conflict with new T47 package claim of 9 watts. #Home depot ultra light disk led sylvania fullAs measured with my Kill-A-Watt meter, T67 power draw at full brightness is reduced by improvements, from 12.5 watts, to 11 watts, as claimed on the package. Diode luminance is reduced, which should make lights more pleasant in ones' gaze. The five tightly-placed diodes, identical in T67 and T47, are increased in size, from 3 mm square, to 5 mm square. Improvements include elimination of buzzing with placement in a dimmer circuit, better efficiency in diodes no longer recessed, surely larger beam angle. Better T67 and T47 LED disk lights have been in Home Depot stores for at least one month. ![]()
