Scottmichaelj Posted February 6, 2016 Author Posted February 6, 2016 So I removed and returned my all my Philips Slimline LED bulbs as well as the Cree bulbs/6" recessed cans TW LEDs to Home Depot. While I was there I picked up some Philips 60w equivalent LED bulbs in daylight color that use only 9 watts. Its only been a few days of testing BUT I have no humming, no flickering and it seems my Cree Ecosmart recessed cans are also now working fine and not flickering. I suspect (but dont have any hard proof) that by adding more of the Philips Slimline LED bulbs it must have introduced more noise on the power line. So while a few worked, the noise wasnt high enough to cause issues. As more and more of the slimlines were added it added more noise causing me to see the flickering. Once removing all of them and putting in these new Philips along with the previous ones I posted that work my issues went away. Heres a link to the bulbs: Philips 60W Equivalent Daylight (5000K) A19 Dimmable LED Light Bulb http://thd.co/1HJa9VN Some pictures of the packaging: Would be happy to hear feedback from anyone else using these good or bad. Ill post back if things change or if they burn out etc.
jerlands Posted February 6, 2016 Posted February 6, 2016 So I bought two types of leds today and both dont work. I put the new bulbs in the flickering recessed can and a lamp at the same dim level and all flicker. For fun I put two of the older flat head Philips leds (older type that look like the Hue bulbs) in both a 40w equiv (470Lumens) and 60w equiv (830Lumens) into the recessed can that was flickering and neither flickered with these bulbs in the lamp or can. This is not scientific but I wonder if the higher equivalent leds notice more flicker than the lower equiv leds. I dont know but this A21 100w equiv flickers bad at all the ranges but high (still some flicker). Maybe thats why some people who have leds dont notice this because maybe they use 40w soft white? Just a thought. Heres what I bought: Cree 100W Equivalent Daylight (5000K) A21 Dimmable LED Light Bulb http://thd.co/1qdUTvD ImageUploadedByTapatalk1453411860.796209.jpg I must have well over a dozen Cree bulbs and never had a problem with flicker. However, my first failure just happened in a Southern exposed inverted fixture where the 100W Dimmable separated from the base, fell onto the ground breaking the globe. I don't recall how long ago I installed it but kinda disappointed this could have happened.. Jon...
larryllix01 Posted February 6, 2016 Posted February 6, 2016 (edited) I have about a dozen Cree bulbs of different types and they all worked perfectly for about 3 to. 4 months. Now two have died and three others flicker without dimming. One did brightness dips so bad I have replaced it. It was a $40 BR40 bulb and was not on any Insteon device or dimmer. I won't be buying any more Cree bulbs in the future. I have a 5 bulb fixture now with three different vintage Cree bulbs and they all dim on different curves. Edited February 6, 2016 by larryllix01
Teken Posted February 6, 2016 Posted February 6, 2016 I fear some of this is driven by the consumer where we expect to see low prices for these wares. I am a little surprised Cree as a company would allow such poor quality but than again this is typical in most companies.
Brian H Posted February 6, 2016 Posted February 6, 2016 I would have hoped the shell falling off issue would have been addressed by now. My early ones the shells got loose and could be popped off. The flickering and pulsing could be the contact springs they used between the driver PCB and the LED PCB. I have a few where I could gently, with a plastic soldering tool, press on the contacts and they would work again. Also saw small burn marks on the contacts where the spring clips where arcing. I don't recommend folks poke around in them. The LED's are in a series setup and the voltage on the contacts is about 218 volts DC and if the LED's are not making contact. Driver runs around 285 volts DC and holds a charge with no load on it.
larryllix Posted February 6, 2016 Posted February 6, 2016 (edited) Thanks for those tech heads up Brian. If I knew how to get the glass off, I would have been into them by now, because I don't expect much out of the Cree help line, although I haven't bothered yet, experiencing the receipt demand right up front. My guess is they have installed poor grade caps also and the power supply shows voltage dips amplifying them at the light output due to soft start circuitry and no soft off design.

jerlands Posted February 6, 2016 Posted February 6, 2016 I don't know how other manufactures connect the base to the globe but the contact surfaces on the PCB are definitely corroded. Jon...

Brian H Posted February 6, 2016 Posted February 6, 2016 (edited) The original ones with the silicon like glue. Bake them at about 200 Degrees F for maybe 30 minutes. Grab with thick gloves. Top should pop off. If memory serves me some of my latest ones had a different glue and didn't budge after the baking. There is a thread on the Candlepower Forums on the Cree 100 Watt ones failing. http://www.candlepowerforums.com/vb/showthread.php?411223-Cree-100w-daylight-bulbs-keep-dying-Anyone-else-have-that-problem&s=2434390dcdd8f3e25e14db866b40f1c9 Edited February 6, 2016 by Brian H

Jon... That's good to hear as HD overall has been very good about warranty returns. Make sure you have a receipt because that's always going to be a real PITA if you don't! ========================= In the end, we will remember not the words of our enemies, but the silence of our friends.

larryllix Posted February 7, 2016 Posted February 7, 2016 HD will not take lightbulbs back. I had one didn't know what to do and just slipped me a replacement once without any records but since they just tell you to call the Cree number on the package.
jerlands Posted February 7, 2016 Posted February 7, 2016 I just contacted Home Depot and after I don't know how many menu selections finally spoke to someone (Wayne) who claims Home Depot has a 90 day return policy. I specifically asked about LED light bulbs and his response was yes, they will accept return of failed bulb w/ either receipt or CC within that 90 day purchase period. Seeing I'm probably over a year into this bulb I'm left only now with Cree directly. Saved me an unnecessary trip anyway Jon...
larryllix Posted February 7, 2016 Posted February 7, 2016 I brought a bad led bulb back and the newbie looks at the tip and found a scratch and told me the policy is not to return any bulbs. Now this was their cheap Utilitech brand and I told them it was junk. It took three seconds to light up. That was probably the clincher, returning for bad quality, not defective.

Scottmichaelj Posted February 8, 2016 Author Posted February 8, 2016 Proven used. That was supposed to be "why shouldnt they" take it back. Guess the US has more liberal return policies.

I believe if I would have lied and stated the bulb didn't work it may have been a different story but I tried to tell them their new Utilitech brand bulbs were garbage and get my money back. I think the brand name migrated from Lowes back a year or more ago,

I think the brand name migrated from Lowes back a year or more ago, I tell them I dont like X within the 90days with my receipt and Lowes always takes care of me. Receipt no problem. Now they can scan your CC to find the purchase too. You canooks have a hard life.

Now they can scan your CC to find the purchase too. You canooks have a hard life. That is all the same in Canuckistan, here. HD has a policy not to take back used lightbulbs or other half consumed products. I have bought products from the Canuck Home Hardware chain and taken them back to HD for a profit without any card or receipt. I have also attempted to return products to HD that they have changed brands, or style, (UPC code) and the scan just turns up, "Sorry, not our product" Edited February 8, 2016 by larryllix

Hello Jon, That is really great to hear this is what service after the sale is all about. As I am sure you know lots of time people will just push the whole *Stupid* so far about not having a receipt etc. Good to know someone on the other side was using some common sense. Please do follow up with the forum members as to what comes and if anything is amiss.

Please do follow up with the forum members as to what comes and if anything is amiss. Ok.. so 10 days after contacting Cree my replacement light bulb arrives UPS nicely packaged and all. However, after opening I discover what I've received is a package which has already been opened for one reason or the other. Not certain if it's a return item or if a repaired item but the packaging definitively has been opened. You can see the left side of the plastic covering the bulb. Anyway.. plugged it in and it works.. Jon... Edited February 18, 2016 by jerlands
