![]() The table and following text were posted, following attendance of an LED lighting trade show in Portland, Oregon. With good downlighting as surface mount LEDs, no one should newly install a can light. You will be less happy with buzz of a dimmed BR30 LED flood. No problem with the Sylvania LED Disk light. Its frosted lens should be projecting from the ceiling for Table brightness, and this will be unlikely.Īdjusting to B4 where brightness would else be greater, is by dimming. That BR30 LED flood looks OK, but it had better be in an air-tight and sealed can, fully covered with insulation if in an attic. Incandescents should be all in the trash by now. No CFL is still in the game, and each still playing had better be disposed with collection of its mercury (wishful thinking). The Sylvania LED Disk light, a surface mount LED with full reveal of light, is the winner now. Where brightness is other than B4, multiply purchase and operating costs by 4, and divide by the brightness number. ![]() Brightness numbers are assigned, and costs are referenced to those of a 100-watt incandescent bulb, B4. point-source lights (bulbs), where the brightness advantage of directional light is included. Lumens per watt for the T67 is 650/12.5 = 52, same as Glimpse.Īt, add table of savings with plate LEDs including the flood bulb of the previous post, vs. I try the Sylvania in temporary replacement of a CREE/ Home Depot T67. 750 lumens for 14.5 watts, 51.7Īt add a new Picasa Web Album showing Sylvania installation in a can light that lacked clips for the engagement springs of a Glimpse light. Will Lighting Science compete, in improvement of the Glimpse?Ī 6" Glimpse from a new production run, May 2013, is unchanged, still 34% behind the new Sylvania in lumens per watt. The Sylvania is at left, accepted as brighter by 20%, the lumens ratio, 900/750. These lights have always been silent on a dimmer. Mod 2 lights start instantly and behave perfectly on a good Cooper DAL06P dimmer. All criticism of behavior problems is resolved. The release is not publicized by Sylvania, so I will commend it. Photos are at bottom of this Picasa web album, with captions:Īt, note issue of a major improvement of this light, that I will call Sylvania 70732, mod 2. ![]() This solution may be needed for many months, awaiting factory changes and shipping from China, and Sylvania must not declare that repair voids the product warranty.Īt, note further improvement of this product. At, I found the interfering lug is easily nipped off with side cutters. My Lowe's store would take back this light as defective, but would not have anything better to offer, unless still holding a few 70732 mod 3. I think the flat head screw is more adverse. The screw head interferes with the clip whether the head is flat or round.
