Chip | Getian/ Reliable Products | Bridgelux /Epistar | Getian has got certificate of Authorization from Bridgelux and Epistar. Build strategic partnership with Bridgelux. High reliability. |
Others/Poor Quality Products | Other brand/ fake Bridgelux & Epistar | Fake chips cost much less. A huge price gap.The actual power is much lower than claimed. (eg:100w usually 70w actual.)Shorter life span with great light decay. |
Notes | Fake chips lack reliability. Be cautious especially when using outdoor. Hard and costly to maintain. |
Phosphor/ Silica gel | Getian/ Reliable Products | Intermatix/ patented recipe and improved technique. Find a best combination of the ratio between phosphor and silica gel. | When temperature goes high, phosphor can resist it and keep the CCT value stable and even from different angle. |
Others/Poor Quality Products | Intermatix/ others (recipe unknown) | Color temperature will drift when temp. goes high. CCT not even distributed from every angle. |
Notes | Our phosphor recipe has been successfully applied for 10 years. |
Gold Wire | Getian/ Reliable Products | 1.2mil 1W / 1.5mil COB / Purity 99.99% | High purity gold wire has better ductility. Resist high current shock. |
Others/Poor Quality Products | 1.0mil 1W/ 1.2mil COB / Al alloy | Easy to break, more likely lead to led failure. |
Notes | About 80% led failure comes from the break of the gold wire. |
BBOS Technique | Getian/ Reliable Products | Gold wire double attach method and small arc, soldering ball | BBOS technique increases reliablity and decreases the risk of the break of gold wire. |
Others/Poor Quality Products | One time soldering | Higher risk of the break of gold wire. |
Notes | No extra soldering ball or small arc added will cause potential risk of wire soldering point falling off. |
Silver Epoxy | Getian/ Reliable Products | Purity 95% (plus microelement) | Tested many times and proved reliable.(suitable proportion) |
Others/Poor Quality Products | <95% / or even use transparent insulation paste | Transparent paste has very low heat conductivity, 1/25 of silver epoxy. Although intial lumen is high but light drop fast. |
Notes | Microelements will help increase the adhesiveness. Higher the purity better the heat conductivity but decrease in adhesiveness. |
Copper Base/ Soldering Pins | Getian/ Reliable Products | Red Copper/ Copper covered with silver/ PPA (white part) | High heat conductivty. Red Copper: 400W/mK |
Others/Poor Quality Products | Yellow Copper (brass) / Aluminum, Steel | Low heat conductivity. Yellow Copper: 100W/mK. Aluminum: 205W/mK. Steel is easy to corrode. |
Notes | The heat conductivity of red copper is nearly 4 times higher than brass. PPA material has good high temperature resistance |
Silver Plating (on the reflection layer of the chip) | Getian/ Reliable Products | Thickness 100-120Ü | Suitable thickness layer |
Others/Poor Quality Products | 40-60 Ü, 60-80Ü, 80-120 Ü | Copper substance will go up through the thinner layer when lit up, causing blackness on the silver layer thus decreasing the brightness. |
Notes | Not too much silver plating either, which will cause decrease in adhesiveness. |
Color Separation | Getian/ Reliable Products | 2 times | Guarantee good color unity. Normal range within + -250K |
Others/Poor Quality Products | mostly 1 time | Wider range or not so consistent. |
Notes | Phosphor Spraying (first time check); Binning (Second time check.) |
