		<title>Question: CFL Track Lighting</title>
		<link>http://ask.metafilter.com/116820/CFL-Track-Lighting</link>	
		<description>Anyone found an energy efficient and cost effective CFL track lighting system?  LED possibly? &lt;br /&gt;&lt;br /&gt; Most track systems found at your local home improvement store only come with a Halogen option.  Halogens are generally not very energy efficient .</description>

		<description>You&apos;re only seeing halogen because you&apos;re only looking at tiny little MR16, MR11 or GU10 fixtures.  You can still get the bigger (and far less stylish) track fixtures which take screw-in bulbs; they will work with CFLs.  You can also get LED bulbs in an MR16 or GU10 form that will fit in the smaller track fixtures, but you&apos;ll probably have to order them online.  The color rendering of LED&apos;s is still pretty lousy, which is why most people won&apos;t buy them, which is why your local big box doesn&apos;t sell them.</description>

		<description>Forgot to mention, LED MR16s also tend to be much less bright than their incandescent counterparts.</description>

		<description>Check out Ceramic Metal Halide options.  Most major manufacturers (Phillips, Sylvania, GE, etc.) offer a range of these types of bulbs.  I don&apos;t know your application, but these are great for retail lighting applications and provide great color rendering.  You would probably need to get them at a lighting supply store not home improvement store.  These are not as efficient as CFL or LED, but much more efficient than halogen.</description>

		<description>I attempted to replace MR16 halogen downlights with a more efficient globe.&lt;br&gt;
The MR16 are the low voltage type, and the only options appear to be lower wattage halogens (20w or 30w) or LEDs, either 20+ LEDs in each &quot;globe&quot; or one to three 1W LEDs.&lt;br&gt;
I tried these in the lighting store, and to say I was underwhelmed...well, they are pretty dim, and very costly per unit. To see some of these, here is an &lt;a href=&quot;http://shop.ebay.com/items/_W0QQLHQ5fPrefLocZ2?_nkw=mr16&amp;_sacat=0&amp;_fromfsb=&amp;_trksid=p3286.m270.l1313&amp;_odkw=cfl+mr16&amp;_osacat=0&quot;&gt;Ebay search&lt;/a&gt;&lt;br&gt;
The other option is mains voltage GU10 replacements. These *do* come with CFL options, although the bulb is much bulkier. There are also LED options here. Sample &lt;a href=&quot;http://shop.ebay.com/items/_W0QQLHQ5fPrefLocZ2?_nkw=gu10&amp;_sacat=0&amp;_fromfsb=&amp;_trksid=p3286.m270.l1313&amp;_odkw=mr16&amp;_osacat=0&quot;&gt;Ebay search&lt;/a&gt;.&lt;br&gt;
All these options are considerably more costly per unit than standard halogens, but should be more cost effective over the life of the bulb.&lt;br&gt;
I tried the 11w GU10 CFL in cool white and the 13w GU10 CFL in warm white. Both types take a long time to warm up to full brightness, like the original 1st gen CFL bulbs did, if you used those. I&apos;m talking a minute+.&lt;br&gt;
Even at full brightness, they are a *lot* dimmer than 50w halogens. My wife asks me to turn on the darks these days.&lt;br&gt;
That said, the six I replaced light our otherwise shadowy kitchen, and are on for 12hours+ a day. The difference between 3.6kWh with the halogens and 0.8kWh for the CFL is quite substantial, and knocked 10% off our power bill.&lt;br&gt;
If you can handle the dimness, I would suggest the 13w warm white CFLs as a potential replacement. Here is an &lt;a href=&quot;http://cgi.ebay.com/Brand-New-13W-ENERGY-SAVING-GU10-LED-ALTERNATIVE-Bulb_W0QQitemZ330314272987QQcmdZViewItemQQptZUK_Light_Bulbs?hash=item330314272987&amp;_trksid=p3286.c0.m14&amp;_trkparms=72%3A1205|66%3A2|65%3A12|39%3A1|240%3A1318|301%3A1|293%3A1|294%3A50&quot;&gt;example&lt;/a&gt; showing the bulkier size globe (note it is 240V for UK/AU/EU).&lt;br&gt;
In the end, I replaced the 12v transformers for the low voltage MR16 and used GU10 mains voltage CFL globes instead. Things are a bit dimmer, but acceptable.&lt;br&gt;
If I didn&apos;t have big holes in the ceiling for downlights, I think replacing the fittings with ones that use standard cfl globes would be much preferable.</description>

		<description>The track system is for the interior of our house.  We&apos;ll have about 4 tracks in our kitchen/great room.   The area has a very high (19&apos;) slanted ceiling seen &lt;a href=&quot;http://www.mcnameehouse.wordpress.com&quot;&gt;here&lt;/a&gt;. It&apos;s a fairly modern design and our taste in fixtures is relatively contemporary when our budget allows.</description>
