Attention lighting gurus!
May 13, 2014 in Design Dilemma
I'm looking to put LED bulbs in the exterior cans we have for downlighting. How many lumens is recommended? I'm looking for an LED equivalent to a PAR20 50 W flood. Any recommendations?

I've heard good things about Cree brand, but couldn't find an equivalent bulb in their line.

Here is a link to the Cree light source described above: This LED is rated at 3000K. Below is a Kelvin Scale for your reference.

Clear Lighting... That link took to me a Philips brand bulb rated for indoors. Or did I miss something? Thanks for your help!

This Philips light source is acceptable for exterior use inside of a recessed fixture, in my opinion. Here is a link to a Cree however there is not an interior / exterior rating listed: This Cree also has 100 lumen less light output and is a 2700K instead of the Philips at 3000K.

Brilliant! Lighting & Design
I am a huge fan of the CREE line.
I started testing / specifying / using them as soon as they came on the market.
I (and my clients) continue to be impressed with the quality of light.
Whether you choose to retrofit to dedicated LED or use any Edison based replacement, you'll get great light from CREE.
On lamp type: Do you have to use a PAR20? Can an A-type do the job?
As to the lumen output - The amount you want and the amount you need might be different. Before deciding whats right for you, a few of the considerations: What is the functional use of the space being lit? How far apart are the fixtures? Is a dimmer being used?
As to warm vs. cool - Most users desire or expect light that feels like the light we grew up with (read: warmer, like incandescent). Consider: Does the space require greater color rendering? Is the space inhabited often or very little?
