SMD 2835 5050 3528 Which is the best choice?

Firstly what is SMD LED?
SMD stands for surface mount diode, specifically, through this process, chip is mounted onto a small “desk”, then becomes an LED.LED 2835
LED Encapsulation can be divided two categories: SMD and COB SMD LED encapsulation process takes three steps:
1. Mount the chip onto a desk with adhesive;
2. Connect the chip to system with bond wire;
3. Cover the chip with phosphor to make the colour.
Light-Evolution-BlogEach encapsulation process is named after the dimension of LED, e.g., 3528 meaning 3.5*2.8mm, 3014 3*1.4, 5050 5*5mm.
COB
COB stands for chips on board, which is a different solution than SMD encapsulation. Generally, an SMD LED is mounted onto a desk, and then the desk is mounted onto a PCB. Instead, COB skips the middle step and mounts the chips onto PCB directly, and thus, the cost is lower. Saving money is merely one of the advantages of COB.
Which one should I choose?
Generally speaking, SMD 2835 Design is newer and more advanced than 3014 than 3528. Because 2835 has more effective thermal dissipation system, specifically, a larger heat sink than 3014 on the back, and 3528 has no back heat sink at all, therefore 2835 is able to take higher current and generates more luminous flux.

The form below is the common spec of these LED solutions in these days. The data is based on June, 2013.

LED 3014
We have introduced a range of the two SMD 2835 products as this is clearly the most efficient mainstream SMD LED so far to date.

Incandescent 60 Watt Light Bulbs selling like hot cakes

60wattincandIn the supermarket today I saw these bulbs flying off the shelves (60W filament will be banned in Oct 2014).

Remarkably people still desire these filament bulbs as they want instant light!   Obviously they don’t know about LED bulbs which are actually cheaper, zero cost after 6 months of use when compared to incandescent or halogen bulbs. Bringing the corporate spend to save buzzwords to the home, an amazing return on your initial investment better than an ISA or Solar panels.

Unlike other energy products LED bulbs are instant bright.

If everyone in the UK used LEDs instead of halogens or filament bulbs there would be less of a business case for  more power plants in the UK, 90% of the energy needed to light Britain would no longer be required.

As we all know you can take a horse to water but you can’t make it drink.

LED 2835 light bulbs in stock next week

gu10-2835-470lum2835 LED GU10 dimmable light bulbs will be available in 2 colours warm white 2800K 430 Lumens and near white 4000K 470 Lumens.

Pricing will be £6.50 our cheapest dimmable and brightest LED light bulb to date. Stock will be limited so if you want a bargain get in early.

These bulbs are the next big thing in the evolution of LED light bulbs bringing more lumens than previous LED chips. These bulbs are 5 Watt and will produce 94Lumens/Watt.

Delivery expected on Friday the 30th Aug.

Dimensions TBC 53mm by 50mm.
