Cree-Based, Other Reliable Sources For Leds

[watchthewaves 0]

Considering putting in place LED lighting for the home. Just starting research. Seems like Cree has a good reputation. Anyone can point me to where I can find Cree-based products in Singapore?

Requirements:

- downlights (lots of them)

- bulbs (as replacement for existing lamps - E27, and the smaller one too - E11 or something like that?)

- some wall lights

- floodlights (preferably with motion sensor)

Dimmables would be good.

Going for functionality and quality more than design/aesthetics, so not looking to pay a premium for fantastic design.

Am open to hearing of other non-Cree products too. Just want good, reliable stuff. Don't want to end up a year or so later, the lights dim out or gone, or parts rusting/paint flaking.

Thanks.

Hi, actually alot of stores in sg are selling non-cree led downlights as cree products are expensive.....dun think non-cree product were rust...as cree product is only for the led light used. So how much watts per downlight you are looking at?? maybe you can let mi know as i have a friend who is in this line that could give you a online quotation as the price is better than outside store.

The internals (bulb, driver, etc) I'm looking for Cree-based because I read that they are reliable and last. Open to non-Cree stuff too if I can be assured of the quality. Eg, I heard that for the lower quality stuff, the light output can diminish over a year or two. So your light may not have blown, but the output is lowered so you have to change anyway (eg, because improperly designed heatsinks don't take the heat away and this has an adverse effect). And this I understand may be the more common concern with LEDs, and not that they blow.

Housing needs to be good quality to last. Don't need designer stuff.

Cree is from US.

Nichia is from Japan.

Orsam is from Germany.

There are alot of brand out there.

Nichia was the leading in LED technology and pricing is higher compare to cree.

Led can used branded, no issue.

But Led itself won't work, it will need circuit board to drive.

Design of circuit board and calculation of heat sink is very important.

Example: If you use 3W LED(Claim from Specification sheet) but in the end the brightness is not there.

Due to compound factor too.

Doesn't mean use the best, you will get the best.

See it, feel it and ensure the pricing is ok.

Thank you.

Hi, I am new to this forum. As we are looking to do full LED lighting for our current renovated house. Would love to hear feedback and recommendations on LED lighting. Currently our designer has planned for MR16 (4W) holders for every areas of our house (i.e rooms - 4 set of 2 MR16 LED holders, dining - 4 set of 2 MR16 holder with 1 set of 3 MR16 holder in the middle and as for living room it will be 6 sets of 2 MR16 holders with a fan in the middle. Cove lightings along the border of the windows for all rooms)Can anyone give us feedback if its too much lighting or too little?

I have to say the initial outlay for LED lights are really expensive (very painful to part with so much money) but sounds like to me that the ROI is worth it. Can i say we can get back the initial cost within 1 year of usage?

Have anyone hear of Ai-Led Lighting? Are they reliable? Apparently their LED lights, bulbs and tubes are especially cheap. All are made in Singapore.

Dear sharriejam,

Please be careful upon selection of LEDs.

Please make wise choice.

I do not want to make any comments.

But please check the right color temperature and comfortable level before purchase.

If you find the price and color is not you want, please reject it because is your own house.

If you want to see any led, feel free to pm me. Thank you.

Regards,

Terry

Hi Terry,

Thanks for the advice, when you mentioned color temperature are u referring to Colour Rendering Index (CRI)? If its 3000K for warm white or something else?

[watchthewaves 0]

Colour temperature is measured in Kelvins and is what we usually refer to as warm white (around 2700K+), cool/neutral white (around 4000K+), daylight (around 6000K-7000K), etc.

CRI refers to the accuracy of the colour of the objects you see under the light. 100 is completely accurate. I believe Cree hits 94 to 95. I think 80+ and above is fairly OK.

[terrygerrard 1]

Dear sharriejam,

CRI = color rendering index (CRI) is how accurate to actual color.

Is what bro watchthewaves have mention.

CRI above 80 will consider good.

But please rememeber 6000k(daylight) and 4000k(neutral white) has lower CRI.

Indeed Cree has the highest CRI but it is standalone LEDs testing and is not tested with circuit.

So result will varies too.

Terrygerrard and watchthewaves,

Thanks for the info. Just a thot... So for warm white lighting is it better to have it as 2700k or 3000k?

I notice some led companies are selling warm white as 2700k while some are at 3000k.. According to their product sheet.

[terrygerrard 1]

Dear bro,

Up to individual, no good or bad.

The rating is color varies.

2700k will be more yellow base on specification.

Is good to see the actual product in person. Thank you.

actually are there led bulbs that can be used in conventional light fixtures ?

Thanks

[ayukie 0]

MR16, GU10, E27, E14 base are common in LED bulbs and they fit perfectly in conventional lighting fixtures. However, keep in mind that LED has a specific beam angle whereas tungsten/PLC bulbs have omni-directional beam angle, you need to consider the mounting orientation of fixture matches the projection angle of the LED source.

Hmz so is there one that can directly replace the enegery savings bulkbs ?
