The recent article: LED Bulb Efficiency Surges, But Light Quality Lags states very well the findings of the DOE and others reviewing LED retrofit lamp performance. While well stated, there are severl missing dynamic issues in the conversation that need to be included if LED is to overcome the failure of the CFL to capture the consumer market it so desperately seeks to dominate.

While efficient, there has been no great interest in the consumer market to lamps with poorer quality at higher prices.

While efficient, there has been no great interest in the consumer market to lamps with poorer quality at higher prices.

The CFL lamp has failed in the consumer market for these reasons:

  1. Light quality is poor in comparison to the far cheaper incandescent lamp. This includes color quality, distribution (photometric) pattern is poor (flood type products)
  2. Appearance and fit of the product into existing fixtures – i.e. ugly to look at, stick out of fixtures, create dark spots in shades and fixture diffusers, etc.
  3. They did not last as long as advertised. When switched frequently, the life of a CFL screw base product can be shorter than a long life incandescent. In outdoor cold climate environments, some fail within a few months. In down-lights and enclosed fixtures most fail even more quickly.
  4. They cost too much compared to incandescent of higher quality
  5. They save some energy, but have so many other liabilities the consumer does not take this seriously.
  6. Flickering starts, flicker under dimming, and 120Hz strobe effects from cheap ballast designs
  7. Slow to warm to full brightness – often taking longer to get up to full light than many products are on for in many rooms (pantry, closet, hallway, etc.)
  8. Mercury disposal concerns for some

With Lighting Science Group acquiring Lamina, Philips absorbing Color Kinetics then Genlyte, and Cree absorbing LLF, on top of Acuity acquiring Io, and other similar combination over the last year, it would see that solid0state market is already trying to gel up. Are we really already at the point where its time to focus on market share over innovation? Is this technology already at the point where we know where this is all going, and its time to build the big conglomerates to satisfy the mainstream demand with already known product? I don’t think so (more…)

lr6

The LR6 downlight is the best performing LED downlight product on the market today, new or old construction.

This is the Cree LR6 downlight retrofit. Producing a white light color of 2700k (Incandescent white – also available in 3500k neutral white) at 92CRI, these inserts produce 650 lumens, consuming only 12 watts. This is an unprecedented 54 Lumens per Watt, exceeding even the best Compact Fluorescent downlight products on the market today. The product is expected to last 50,000 hours to 70% of its full light output.

The product inserts into virtually any 6″ recessed downlight housing. Installation takes less than 10 minutes.

In the test application of this product, 4 fixtures were installed in standard Halo H7 housings, with addition of optional brushed nickle trims to compliment the stainless steel trim, which snaps easily in place after the retrofit body is installed.

Comparing the illuminance calculated using the company provided photometric data and actual measurements in the applied space were within 7% of one another, with the actual application being slightly better than predicted. After 9 months, there has been no measurable light loss. (more…)
