Hopefully this is in the right place. I'm currently on the prowl for 4" Led recessed lighting for my home theater project. Does anyone have any experience with this company. If not does anyone have any recommendations for 4" led recessed light packs that are not from homedepot lol.

Thanks in advance.

Let me chime in that you get what you pay for. LED lamps are a long term investment. Those look like cheap Chinese junk to me. Some things that can go wrong with a 'deal' like that are bad/mismatched LED color and cheaply made power supplies. Good LEDs have a 5 (or more) year guarantee. I wouldn't buy them any more than I'd buy a Dollar Store LED flashlight.

I was recommended these lights by somebody
http://www.homedepot.com/p/Commercial-Electric-4-in-Recessed-White-Gimbal-LED-Trim-CER4742WH/203490013#

A little spendy, but they are a retrofit that goes into a traditional can.

I've literally had them in less than a week, but I really like the color of them, which is tough for LED's. And they look good also smile.gif

those do seem a bit on the cheap side, but at the same time, a 25% failure rate(which is super high) would still save you hundreds of dollars.

i recently picked up some 'rotundity' LED's off amazon for my basement, came out to about 6bux per bulb(gu10's) and they were both dimmable and bright enough to replace the 50w halogens. i tried two different companies, the 'rotundity' ones were more expensive. the only differences i saw was the cheap ones weren't dimmable(weren't advertised as being dimmable), well they dimmed, but flickered when you did, and one of the cheap ones showed up as 'warm white'(which actually looked JUST like a standard halogen if you like that yellow light)

i've only had them for about a month though, so pretty new for LED bulbs. but that being said, my halogens were dropping like flies, and after only about 8months it seemed like a bulb was dieing every week.

the best value may come from getting 'normal' housings and buying some economy bulbs. as far as i know, there's not many places actually producing LED's anyway, so while there's still places to cheap out on led bulbs, it doesn't seem to be as big of a deal(i have several chinese/korean/whatever led flashlights that have been great for years). not sure i'd trust the housings and electrical boxes etc unless they were built for your countries spec. i bought a 6pack of potlights with halogen bulbs for about 40bux from home depot. then replaced the bulbs this year with led's

Thanks for feedback. I don't mind buying from the lil guy and trying to support small business. But I will not do that at the expense of my dollar. Nor do I want to be a guinea pig and or loose my money buy buying from over seas. I'm going to go to home depot and see if they can order these in any other finishes / color. I wish they had a contractors pack for LED lights:D

@Fierce_Gt can you link me to you the 6pack for 40 potlights. How much were the replacement LED bulbs? TIA

it was years ago that i bought them, i'm not sure i'll be able to find a current link but i'll try.
EDIT: go figure, this is them: http://www.homedepot.ca/product/promotional-pack-6-3-in-gu10-new-or-remodel-construction-housing-kit-w-6-wh/913709

the LED bulbs i bought were: http://www.amazon.ca/gp/product/B00AY3QYYE/ref=oh_details_o05_s00_i00?ie=UTF8&psc=1 and http://www.amazon.ca/gp/product/B00FHVCO74/ref=oh_details_o06_s00_i00?ie=UTF8&psc=1

both were almost as bright as the 50w halogens they replaced, but focused the light much more directly. i modified them slightly by rotating the lens so it didn't line up and this spread out the light much more evenly. the lights themselves LOOK brighter than the halogens, but there's less light in the room. i went with the pure white models. they seemed to be pretty much the same bulbs, but the packaging, and 'certification' was better on the rotundity ones. the rotundity were also dimmable, and the others were not. the reviews i read before reading seemed to indicate some issues with DOA and short life on SOME of the bulbs. ie, guys would order 10 and one or two would be defective or stop working within the year. i figured since they were about half the price, i can afford to order a couple extras in case that happens. no DOA's for me. it seemed like the name brand ones weren't too much better in this regard either, probably just have more recourse for returns/warranties when it does happen. but i did read a lot of reviews on CREE and phillips bulbs failing as well, and the less well known local brands were basically on par with what i could get online. locally there's a lot of Feit bulbs, which are cheaper than the cree and phillips, but look to be the same as the amazon/ebay ones.

but i'm certainly no expert. this is my first experience with LED bulbs in the home.

I just received a couple more LED bulbs for the rest of my basement(decided to replace every bulb down there so I'm not walking from white light to yellow light)

http://www.amazon.ca/gp/product/B00BY1KZCW/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1

these guys are really bright, easily replaced the 60w traditional bulbs I had in before, in fact I'd say they're pretty much on par with 100w ones. they are dimmable, but dim to 'off' much sooner. my dimmer switch is basically off from about 0-20% and then it dims normally for the rest. the bulbs are VERY heavy though.

http://www.amazon.ca/gp/product/B00BY1N9K2/ref=oh_details_o00_s00_i01?ie=UTF8&psc=1

pleasantly surprised by these guys as well, they are definitely brighter than the 50w halogens they replaced. light dispersion was also very good. I have 3 of them connected to a lutron ir dimmer(something that often has issues with LED bulbs) and it appears having at least three of these connected is JUST enough load to make the switch function. with only 2 connected, they won't turn off. but with 3, they function normally, except the odd hiccup when dimmed very low before/after turning on. if I dim to the lowest setting, then turn them off, one bulb often stays on. if I turn them off from a brighter setting, no issue. and the opposite happens when turning on. if I turn them on to just a very low level, sometimes one or two of the bulbs does not come on. if I go to a brighter level, no problems. I'm guessing with 4 or more connected, this wouldn't happen at all.

again, like the other led's I've tried, they dim well, but not as low before turning off. if you want a VERY low level of light, they aren't good. at the lowest settings they are still fairly bright(think full moon bright).

the other thing, both of the new ones I ordered are 4200K which I think is PERFECT. the first batch I ordered were a little vague on actually color temp, but they must be in the 5000-6000k range, as they are slightly whiter. the 4200k looks very close to sunlight, but still looks 'right' inside. my wood doors, and tan paint in my bedroom still have a warm look to them with the 4200k bulbs. this will definitely be the color temp I aim for from here on out.

still have three more bulbs in the mail to try out, then i'll have my whole basement converted: http://www.amazon.ca/gp/product/B007B6LOM4/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1

This is good. Very good. Heavy means lots of metal (aluminum, typically). This is heatsink. The LED chips are only about 1/100 of a square inch and while they only dissipate about a watt each that is a pretty high energy density. Hence the need for a huge heatsink, especially when there are 5 or 10 of these little chips in a lamp.

yeah, i didn't think anything bad of it, just surprised me, much heavier than the gu10 LED's i already had(thought they are also much brighter, so i guess that makes sense)

just figure it was worth noting on the odd case they would be installed somewhere that would be affected by the weight(it would certainly unbalance a multi-bulb light if not all the same bulb for example)

but that's good to hear that it may be a sign of good quality. i'm so tired of replacing these bulbs all the time, so i'm hoping they are reliable

I've recently installed these on a drop ceiling in my basement.

No enclosure needed.

Great light and easy to install.

I confused MC LED with NC LED. NC is a reputable manufacturer of LEDs...MC I know nothing about. My advice is buy one and let it burn. See how well the heat sink operates. Heat is what drives failures.

I am in the process of completing my basement and tried out multiple LED lights for my 5" cans. I was only happy with one of them, the Cree. The Commercial electric with the built in trim had a turn on delay, the the Halo which uses Cree LEDS but not their electronics would turn green when dimmed. The only ones that didnt have turn on delay and didnt change color temp were the 100% Cree setups, I belive they were called eco-smart. I am still on the fence on whether I want to go LED or halogen, the other thing that I noticed was to prevent strange dimming effets you had to go with an LED compatible dimming switch, which was great, except it then introduced its own turnon delay. At this point I am going halogen but still have a month or so before I am ready to install.

how much of a delay?

of the led's I've tried(all cheapies from amazon) they've ranged from instant to about half a second at worst. certainly not enough to be a deal breaker imo.

what I would like is some that dimmed more. all of the dimmable LED's I've had were still bright enough to read by at the lowest brightness. I've actually considered putting a 'tint' over the bulbs in my theatre since they are so bright, and I'd prefer a dimmer dimmed setting

My brother left today to go to the lighting convention in ShenZhen. I asked he spend some time looking at the latest LED dimming tech. This is a rapidly changing market segment. I hope to post some info in a week or so.

for what it's worth, I had some car tint in my garage from years past, and tried making some filters to put over my gu10's.

I experimented a little bit and there's really no way to get the same performance I had with halogens. 3 layers got me the same dimmed brightness, but less than half the full on brightness. I'm going to try it with the 3 layers in the back of my theatre room for a bit. I have a feeling in the end i'll go back to the regular lighting. I really don't think I need any lights on when viewing, so having brighter lighting for cleaning or whatever will still be more useful than having dim lighting for viewing
