Some states allow 120v /- 5% at your house, others allow/- 10%.
If your house voltage is above the high side for your state its public utility commission might be interested in hearing about it.
I have high voltage… even 130V bulbs didn’t last. And obscenely high water pressure.
I’m assuming that LED bulb failure was just a random thing. We’ll see. In the year it was working, at least 4 or 5 halogen bulbs would have died in the office.
If they don’t make you return it open it up and post it’s guts on here, interested to see who’s LED it is using etc.
Well, since it’s from Sylvania/Osram, I’d assume it’s Osrams.
But then their PAR16 bulbs have four XML’s. I did take apart one of their 15 watt PAR38 bulbs. It had a array chip on it… looked like it may have been from Citizen. That bulb died because it blew an internal picofuse.
You may be able to use a buck-boost transformer in the buck mode to reduce your house voltage and a pressure regulator to put your water PSI at between 20 and 80, commonly 40 to 60.
I took my DED light bulb back to whence it came. They plucked a new one off the shelf and gave it to me (they kept the old one). I asked the guy how many LED bulbs (out of the thousands that they have sold) have they had to replace… a grand total of 4 bulbs (2 Philips PAR38 bulbs, my Sylvania PAR20, and a Sylvania MR16)
I knew some of their stuff did use Cree LEDs, that’s why I was curious, always cool to see where our stuff is being used.
What type of wood cabinets are best suited for LED lighting?
lesliebone,
I strongly suggest you edit your profile and remove your home address from “Location”. Everyone can see your full address.
Cute house. Looks like you just recently bought it.

Hello, I just find your site about wooden cabinet LED lighting. It's a subject I have been interested in much time and others will surely find this wooden cabinet LED lighting very good.
hello, eveyone, here is the link i share with you guys,
music control the bulbs, very nice ;

One of the candelabra bulbs at my front porch gates finally died after 4 years of 10-12 hour/day use (say 15,000 hours). Something on the driver board died. Had to break the bulb to get to it (base was glued, some of the bulbs the base just unscrews). Nothing obvious was cooked. The filter cap was good. So were the LEDs (3 Chinese “egg-drop” emitters). The bulb was surprisingly well built.
3000k-35500k belong the color of warm white,sure,you can use them in dining room,also you can consider use the neutral white,tie color temperature about 4000k-4500k……
hi,lesliebone,may be you need conside what type LED lighting suit for wood cabinet……
I’ve got to say, this thread has been a gold mine, I moved into my new house last month, first thing I noticed, for an English house, there was a LOT of halogen bulbs, mostly 50w 12v mr16’s, so, I started looking around for what was available this side of the pond. Mrs gords loves to have the lights on, I mean literally ten in the morning, all the kitchen lights are on, plus all the lights between upstairs and the kitchen, that’s 22 50w halogen bulbs on must of the day and some cfl’s to boot. I could HEAR the damned electric meter whizzing round and I’m not flush either.
I ended up ordering a couple of philips master 2700k dimmable gu10’s and ceramic holders. After some questions, I’d found out that early generation transformers wouldn’t run one led replacement, one solution I found was to run three or four mr16 led bulbs off one transformer to fool it into seeing a decent load, good plan but it’d mean fishing two core cables all over the shop, remembering which light gave access to the transformer and generally just didn’t appeal to me. Then someone suggested swapping the mr16 12v holders for gu10 240v holders (England remember) The first two were an experiment, would the output be enough? would the tint be acceptable?
Well, these Panasonics seem pretty good, after failing to find a cri rating, I asked the dealer, he said he’d never been asked that before but looked it up, 81cri, acceptable enough for me and the output is indistinguishable from the halogens they replaced, I’ve now got seven out of nine replaced in the kitchen, one in the entrance hall and would have replaced the ones on the landing.
They presented a problem, the old guy had found a big industrial 240v - 12v transformer and used that, all the fixtures were in parallel off that, not the biggest problem but less simple to solve than I wanted, I picked up some osram nw (3000k) multi emitter mr16 (5 or 6w I’ll have to check) I put those in, mainly as a test bed as I’ve found another of those transformers elsewhere, they work ok, bit of a thunk on switch on and a bit cooler than I’d have preferred, but I used my litmus test, I didn’t tell mrs gords, just put them in without saying anything and waited for the complaints about me buggering about………I had to point them out, she didn’t notice at all! that to me, is the best thing, if people dont notice, you’ve found a good replacement, and these were 20w mr16’s I can even run down to one of these on that big ole dumb transformer, so they are fine elsewhere in my case.
So far I’m happy, I’ll order the rest of the bulbs next month, I have had to return six earlier phillips masters, they were a very deep (80mm) assembly and wont fit in the recesed down lights, they’d be fine in a fixture, they’d even look nice but were no good, fortunately, the ebay seller agreed on a refund, no quibbles so I didn’t get stuck with them (thank *k since I ordered drunk and well over paid).
What’s the point? mainly to say thanks to texaspyrp for the helpful info and in the hope I added a little more.
Now, I just need to find two gang dimmers that’ll work with these drop ins and dont cost the earth.
Did she not notice any difference? Where did you get them from? I think I need to try some.
suprisingly no, they are distinctly cooler than the halogens they replaced. I got them from b and q (and paid the premium for it) I just wanted to know if the transformer would drive them and b and q would take them back if they wouldn’t work, I wouldn’t want them in the kitchen, vthe philips kill them in how close they are to halogens but for the landing they work well. I would recommend getting the newest philips masters gu10’s and sone holders, at the best price you can find, there are some good deals to be had on ebay if you hunt them out, I’m averaging £9/bulb and not being too carefull so far, just make sure they are the smaller (50 mm deep I think, rather than 80mm) ones to be sure they will fit, some of my housings I’m going to take back out and snip the cross piece to get a better fit buy otherwise they are good. I’m mainly looking forward to the electricity savings tbh, the install cost is high compared to halogens but should be recouped inside the first year of use, if they last as long as they are supposed too, they’ll outlast five or six halogen bulbs in the same fitting too, at that point they pay fir themselves.
The main thing was finding ones that put out as much light in the right tint with decent cri, id have tried the syvanias tp mentions above but they were about forty quid a pop………I can’t stretch that far, the Philips were within reach.
if you do go for mr16’s, make sure your transformers will run them, of the sixteen individuals in my house, none would run an led drop in, so I’d have had to buy the transformers too, I got 20 gu10 ceramic bulb holders for four quid, they didn’t need to be ceramic but that was what was available.
Good luck and give them a go, one thing I have noticed tonight, we always leave the kitchen doors and all the windows open, the house is usually full of moths and daddy long legs, tonight, I’ve not seen one, I guess that’s down to the zero uv emmission of the led emitters but I don’t know for sure, need to use them some more first.
It could be. I get that if I leave my daylight CFLs on, but they don’t seem to be attracted to low power halogen (5-10W). >.< Thanks, gords!
Looking at the prices of the Philips Master range is making me think about buying some cheap and replacing the LEDs though that could be costly too. :~
That’s Very Interesting!! Please tell us more? 
Yes, almost all bugs ignore or are blind to white LEDs.
One other thing that I have noticed with the LED fixtures is an increase in cobwebs around/in them. The bulbs don’t get hot enough to fry the critters that make them and burn off their web stuff (halogen bulbs get to several hundred degrees C… hence the ceramic connectors). Cobwebs are actually a good thing… they help filter/trap gunk in the air.
