+<p>The figures above aren&#8217;t entirely accurate as the power meter I&#8217;m using is
+only montoring amps to 2 decimal places, and watts to whole numbers. From
+some of the calculations I&#8217;ve done, these figures aren&#8217;t even rounded, they&#8217;re
+just&nbsp;truncated.</p>
+<p>The comparison between the two lights isn&#8217;t exactly fair or exact. The <span class="caps">LED</span>
+straight replacement is a lot brighter than the fluorescent tube, but the
+fitting I&#8217;m putting the LEDs into is really designed for the 360 degree nature
+of a fluorescent tube. The LEDs are only 180 degree light&nbsp;emission.</p>
+<p>The colour of the LEDs in this instance is really terrible &#8212; the colour is
+essentially purple/pink. In order to counter this, I&#8217;ve opted for colouring
+in the lights with a yellow marker, in order to filter out some of the red and
+most of the blue in the light, and roughly restore the light to a &#8216;natural
+white&#8217; like it was supposed to be the in the first&nbsp;place.</p>
+<p>This serves as a lesson to try and buy from a reputable seller online or try
+and buy one before committing. <span class="caps">LED</span> colouring can be really messy, especially
+when dealing with manufacturers in other countries&nbsp;directly.</p>
