Layout lighting: replacing Halogen lights with LED lights

Would it be worth it to switch to LEDs?

Yes, it is definitely beneficial for the reasons that you have stated. An added benefit is the ability to tune or accent the appearance of different areas of the layout with various color temperatures.

Also, what Kelvin rating would be best for any flood system?  These LEDs seem to come in only 3000K or less.

The 2000-3000 range is "warm white" which is what you are accustomed to now. The 3000 would be like using a 500w bulb. Kind of intense. 2500-2700k would be closer to the current bulbs.

Philips Lighting is an informative site as well as searching the terms "color temperature" and "led color temperature". I feel you'll have to actually see the lights in person to determine which temperature you like.

Once you decide which color that you like, compare the mfg.'s rated avg life and beam angle. Then choose the cheapest for your specs.

Here's a few charts attached.

I wouldn't spend the money on LED's yet, because those prices will come down. We used CFL's which cut down on the heat and energy consumption. The biggest thing is the bulb's color....we went with 5000k for a bright daylight look instead of a warm 3800k bulb which has a yellow glow to it.

Moonman,

Thanks for the great info.

Laidoffsick,

I was looking at LEDs to use in my already installed ceiling light fixtures.  I have not seen any CFLs that would work.  I do like your thoughts on using the daylight bulbs.  Thanks.

I have replaced lighting in two homes, changing from incandescent/halogen to LED's and CFL's. The MR16 fixtures accept replacement LED's. Decide first if you want to be able to dim the bulbs, not all can be dimmed. The color rendition index or color fidelity of the bulb is much more important than the exact color temperature. CRI should be at least 93% for layout illumination. Not all LED's have this on the package. Most of the cheaper LED bulbs are in the 83 to 87% range. Side by side the difference is noticable. I recommend 3500k if you can find them. I have 3000k bulbs and they are great as well. Expect to pay about $15 each for dimmable, 3000k, 93% CRI LED's. The only equal quality 3500k bulbs I located were $27 each. 

I absolutely think it is worth it to change the bulbs. 

A good full spectrum light bulb is the GE Reveal. It's uses blue colored neodymium glass. They are used by museums and jewelry stores. I got mine at Lowes an 8 pack of 75 watt for $10. So what if they use some power. I only average a couple hours a week on the layout.

If you are lighting your layout.. you do NOT want 3000k or 3800k bulb, those are for general lighting in your home. As Gary said, you want a FULL SPECTRUM bulb for that, 5000k or close to it.
