title: Magento- Get a custom attribute of a product by sku
body: <p>I am trying to display the value of a custom attribute using the sku of a product.</p>
  
  <p>Accessing the name attribute works perfectly for me using the following:</p>
  
  <pre><code>echo Mage::getModel('catalog/product')-&gt;loadByAttribute('sku',$bulb_merge)-&gt;getName();
  </code></pre>
  
  <p>However when i try this for a custom attribute:</p>
  
  <pre><code>echo Mage::getModel('catalog/product')-&gt;loadByAttribute('sku',$bulb_merge)-&gt;getTechnologies();
  </code></pre>
  
  <p>I receive an integer number.</p>
  
  <p>Id appreciate the help.</p>
  
  <p>thank you</p>
