LED Module Quality taking a dump

[Erik Sine]

With Principal LED and Sloan's V-series (value line) LED lines hitting the market at extremely low pricing I noticed a surge in shops literally flocking to save on peanuts.

 

Here's a warning, be weary....It seems like Principal LED has taken a large step back in LED module quality as all their LED modules have gone all Constant Voltage.....no longer Constant Current.  

 

Sloan's newest Value 4 line....the 2LED Module is now .96 watts per module with modest light output for that power....this module is also Constant Voltage Not Constant Current.  My thoughts on Sloan is for a high wattage module for modest light, it means the chip quality is not very efficient (Light output for power in).  They're having to pump in more juice to get more light.  More power means more heat, more heat is what kills LED life.

 

Constant Voltage Modules have no current regulation, their dependent on resistors and light output for the first module on a string is brighter than the last on that same string.  Constant Voltage Modules have a much shorter life than a current regulated Constant Current LEDs, where all modules on a string are equally bright.

 

An efficient LED chip will put out more light for lesser power, the lesser the power the longer the life.

 

Hold on to those long warranties....if they're still valid.  You'll have a lot of paperwork to fill out and keep track of

 

 

Sometimes companies get so large they end up using their name to sell products for products that use to be better....

 

Just some thoughts and opinion
