GETIAN High Power LED Material Introduction & Comparison

Getian/ Reliable ProductsBridgelux /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.
NotesFake chips lack reliability. Be cautious especially when using outdoor. Hard and costly to maintain.

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 ProductsIntermatix/ others (recipe unknown)Color temperature will drift when temp. goes high. CCT not even distributed from every angle.
NotesOur phosphor recipe has been successfully applied for 10 years.
Gold WireGetian/ 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.
NotesAbout 80% led failure comes from the break of the gold wire.
BBOS TechniqueGetian/ Reliable ProductsGold wire double attach method and small arc, soldering ballBBOS technique increases reliablity and decreases the risk of the break of gold wire.
Others/Poor Quality ProductsOne time solderingHigher risk of the break of gold wire.
NotesNo extra soldering ball or small arc added will cause potential risk of wire soldering point falling off.
Copper Base/ Soldering PinsGetian/ Reliable ProductsRed Copper/ Copper covered with silver/ PPA (white part)High heat conductivty. Red Copper: 400W/mK
Others/Poor Quality ProductsYellow Copper (brass) / Aluminum, SteelLow heat conductivity. Yellow Copper: 100W/mK. Aluminum: 205W/mK. Steel is easy to corrode.
NotesThe heat conductivity of red copper is nearly 4 times higher than brass. PPA material has good high temperature resistance
Color SeparationGetian/ Reliable Products2 timesGuarantee good color unity. Normal range within + -250K
Others/Poor Quality Productsmostly 1 timeWider range or not so consistent.
NotesPhosphor Spraying (first time check); Binning (Second time check.)
