More commentary on the CREE CR6

January 1, 2011

I received a comment on yesterday’s post about the CREE CR6.  Rather than leave the comment and the response buried in a comment section, I’ll pull this out into a front-page continuation of yesterday’s post.

Mike, not to be a spoil-sport, but I don’t think a $50 light bulb is worth getting excited about. First, LED’s don’t use dramatically less energy than a CFL (the $200 savings is compared to an incandescent). Second, if a product can’t pay for itself in a couple of years, most people aren’t going to bother.  Finally, the 35,000 hour life expectancy is a bit misleading. That works out to more than 20 years at 4 hrs a day (someone energy conscious enough to spend $50 for a bulb is probably obsessive about turning off lights that are not being used presently).

While LED’s offer some aesthetic and performance advantages over CFL’s, the price probably needs to drop below $10 before they make any sense.

Hi David,

The right LED lighting makes a lot of sense right now!  And I’m going to get excited anyway!   On a New Year’s morning, here’s a thumbnail version of the reason why.

I like the non-energy performance and appearance of the CR6 and LR6 better than the incandescent they replace.  And some people like “better” over “cheaper”.   When “better” is cheaper than “cheaper” that’s even better!  (Whew—try saying that fast five times.)  And over the life cycle, these certainly are less expensive.

I disagree with your statement that “if a product can’t pay for itself in a couple of years, most people aren’t going to bother”.  That is a common fallacy in the energy-efficiency world, and it ignores the real reasons that most of our customers pursue energy-efficiency, namely for comfort, health & safety, durability of the home, and even aesthetics!  Energy-efficiency is often a nice way to pay for these benefits for many people.  And examples of this abound.  Windows is one—and we see payback on windows stretching to 40 years-plus in some cases.  [By the way, this doesn’t mean we don’t educate people about the low-hanging fruit of air-sealing, insulation, duct-sealing, etc.  We install more of those services than windows.]   What’s the payback on a granite countertop?  A sofa?  An Xbox?  A trip to the Grand Canyon?  What’s the payback on making your daughter’s bedroom more comfortable all summer or winter? 

As I’m sure you’re aware, many people don’t like and won’t use CFLs.  And even though I used them in recessed light applications, the quality was inferior than incandescents in characteristics including light quality, color rendition, and dimmability.  And that means that the stuck with incandescents.  I’ve noted this in the California market, for example.  In these cooling climates—and high electricity rate markets—in particular this is a shame.  Not only are people forgoing the savings on the lighting side, but the inefficient lighting is dumping heat into the space that they there pay to remove with air-conditioning.  A double whammy.  Having a product that people are willing to use is a game changer.

In new construction applications, or retrofit applications where trims are being installed (or replaced) anyway, the cost is the CR6/LR6 is actually overstated by about $10—because it includes an integrated trim already.  Plus, installation is quicker than with a two-step trim-lamp-process.  Not much, but minutes add up.

In some high-bay applications with 9-, 10-, or higher ceilings, a 35,000 hour life (or a 50,000 hour life in the case of the LR6) is a huge deal.  Some people have to pay a professional to change their lamps—and avoiding this covers the cost of the LEDs even without the energy savings!   This is certainly true in commercial situations as well.  You may be handy and not afraid of heights or ladders (and have the appropriate ladder), but for some people this is a very important factor.

I’ll note that it took me three tries to find these at the Home Depot in NY—because they’d already sold out at the first two and they were waiting on the next shipment.  So some people are recognizing the value already. 

These already make sense.  We don’t need the price to change a penny for that to be true.  I do agree that they won’t have broad market appeal at that price point yet.  I’ll expect the prices to drop steadily in the coming years.  They have already dropped over the last 18 months.   But people can feel good about starting savings today.

Happy New Year!
Mike

CREE CR6 Review–A bright spot in efficient lighting!

December 31, 2010

The long-awaited full review!  And let me cut to the chase:  When it comes to LED recessed lighting, right now CREE is the top choice, and the new CREE CR6 stands strong alongside its LR6 sibling.  The CREE CR6 is a winner!  I’ve tested a dozen different makes over the last month, and the CR6 and LR6 beat all the competition hands down.  (I’ll provide a review of the others over time—but I won’t tease you waiting for the answer about which is best–CREE wins.)

Unlike some of the energy-efficient lighting involving significant performance compromise, the Cree CR6 holds its own against the 65-watt incandescent recessed bulb it is intended to replace.  In fact, I like it better!

Available in a “warm” (2700K, for you technical types), it looks great.  Its high CRI of 92, objects it lights look like you’d expect and don’t take on a ghastly pallor. 

CREE CR6Performance-wise, it came on instantly just like an incandescent.  That sets it in stark contrast from most others we’ve tested. It also seems to dim almost as well as an incandescent and better than even the best dimmable CFLs we’ve tested. In terms of brightness, it’s rated at 575 lumens, however perhaps because of better efficacy (how much light leaves the fixture v. how much gets trapped) this seemed brighter than its CFL competitors.   (Note:  the LR6 has a higher lumen rating at the same 10.5 watts.)  The CR6 has great dimmability when matched with a Lutron Diva dimmer.  Unlike most of the LED competing products, the individual LED diodes are not visible—instead we see a warm, very uniformly glowing surface.  It’s a beautiful light that I like better than the incandescent it replaces!  When energy-efficiency comes with better performance, it’s a no-brainer!

The unit is rated at 35,000 hours—something I obviously haven’t had the ability to test yet!  I can report that the CREE LR6’s are still performing great after almost two years of daily use.  The long life span makes them an excellent choice in harder to reach ceiling fixtures.

The CR6 was very easy to install, and it worked great in the three different 6” housings that I tried it with.  Both the CR6 and the LR6 (and the LR4—which I also like!) come with an integrated trim.  The only downside of this is that if you have an existing trim you really like, you can’t use it with the CR6.  The CR6 trim looks great, though, better than most of the trim kits it replaces, and I would gladly remove existing trims to use this.

The price may shock some.  It’s going to be in the $50 to $65 range.  I purchased mine for $49 at a Home Depot in New York, where NYSERDA subsidizes the cost.  But at 10.5 watts, it should save you an estimated $200 or more over its life, depending on your electric rates. 

I’ve had trouble locating the CR6 locally.  And it’s still hard to find.  But it is available through Amazon.  I got mine at a Home Depot under what appears to be their Ecosmart house brand.  (They also sell other LED products under that branding—so make sure you get the right one “powered by CREE”).

As mentioned previously, the CR6 and LR6 are not yet rated for wet locations—although I’m told those products are on the way.  If you have a wet location application (like a shower), the Halo LED Module product is a good, albeit more expensive, choice.

I heartily recommend the CR6 (and the LR6), and I’ve installed it in my own home!

What do others think?

CREE CR6 is on the streets–and it looks like a winner!

December 19, 2010

[Note–see longer review posted on Dec 31, 2010.]

I finally got my hands on a the LED CREE CR6 for recessed lighting applications and gave it a quick test run.  It looks and works great.  I’ll post a more complete review soon, with pictures.  Meanwhile, I’m giving it a big thumbs up.  It and the CREE LR6 stand at the top of the heap, with HALO’s LED fixture not far behind (and ahead in a few applications).  Here’s a product that in many respects beats all comers in its class–incandescent, halogen, and flourescent (and other LED) lighting.

Thanks,
Mike

STILL waiting on CREE’s CR6

September 12, 2010

[Note–see review posted on Dec 31, 2010.]

I know I said I’d be reviewing the CREE CR6.  And I will…if I can even get some.  My local suppliers keep saying another month, another month, the story they’re getting from CREE.  A lot of folks have contacted us looking for more info.   As soon as I can get my hands on the product, I’ll let you know.

Meanwhile, do check out the posts on the CREE LR6 and HALO LEDs, ready-for-prime-time products.

CREE CR6–Still Waiting!

June 29, 2010

A couple folks have asked about how CREE’s CR6 LED light performs.  I wish I could tell you!  It’s still not available locally (we’re told the end of July).  But we’re looking forward to trying it in the field and to see if it stands up to CREE’s LR6-a solid performer.  Stay tuned.

Thanks,
Mike

New CREE CR6–LED Recessed Light

May 15, 2010

[Note–see review posted on Dec 31, 2010.]

Energy-efficient lighting is an important part of any green home.  As such, I’m looking forward to trying the new CREE CR6 LED light.

It doesn’t look as robust as CREE’s LR6 (see earlier review); however, it has very similar specs and a much more affordable price point.  We’ll have to see how it performs.  And if HALO or other manufacturers respond with something similar.  Stay tuned.

Thanks,
Mike

HALO LED lighting

November 6, 2009
HALO LED recessed lighting

HALO LED Recessed Lighting

Halo lighting has some  recessed LED lighting available.  It’s good stuff, and I wouldn’t hesitate to install it (in fact, I have installed it my own home).  Right now, I do like the CREE product better, but part of that is personal preference.  Some quick observations:

  • The HALO product is available in a 3000K temperature with a CRI in the low 80s.  The light isn’t quite as “warm” looking at the CREEs (the 2700K product), and the color rendition doesn’t seem quite as good to my eye.  And, personal preference, I prefer the warmer look in a residential setting.
  • The HALO LED isn’t quite instant on.  I experience a slight delay after flipping the switch before the light turns on.  It’s not a big deal, but again, the CREE product holds on advantage.
  • One important HALO advantage:  it is currently available with a “wet location” rating that you’d need in shower enclosures, for example.  CREE does not yet have product for this application.
  • The HALO products does offer a broader range of trim options than CREE.  If you need a particular style, HALO may be the way you need to go.
  • The HALO product–with trim purchased separately–was much more expensive the the CREE at local suppliers, as much as $60-90 more than the LR6.

My bottom line:  I like the CREE product better, and would chose it in most instances.  However, I wouldn’t hesitate to use the HALO–and it’s got to be HALO in wet locations right now.  I like either of them better than similar compact flourescent products.
