Default LED Developed for Halogen Lamp Replacement (Another One)

[just FWIW and nothing more]

IMM Photonics introduces a newly developed LED featuring a continuous spectrum from 400 nm to 750 nm. Standard white LEDs have a gap in the spectrum between 400 nm and 450 nm and around 500 nm. The new WISPEC-LED closes this gap.

IMM combined four LED chips on one compact LED substrate to deliver homogenous white light.
Perhaps most interesting:
Quote:
. . .the light can be individually adjusted because the chips can be controlled independently from one another. For example it is possible to generate "Cool White" with a colour temperature of > 7.800 K. ACRI (Colour Rendering Index) value > 90 can be realized as easily as a lighting current of >130 lm. A colour mixing stick (optional) will allow for homogenous localized and spectral light distribution.

Due to pulse-width modulation (PWM),the LED is also dimmable by a ratio of 1:400 without changing its colour temperature.

Default Re: LED Developed for Halogen Lamp Replacement (Another One)

When it comes to CRI, anything over 60 is plenty for most purposes. Typical LEDs already have a CRI of ~80+ which is virtually indistinguishable from 90. It would be like saying a 90mW laser is vastly superior to an 80mW laser.

Sounds like their marketing department was bored.
