2015 Holiday Gift Guide Series. Last week we looked at great ideas for the custom bobble heads designed to look like the recipients are a fun gag gift that is guaranteed to be one-of-a-kind.

If your active grandparent hasn’t discovered the outrageously fun sport that I can only describe as a cross between tennis and ping pong, then gifting them with their own bluetooth tracking tag that hooks onto your keyring (or anything you find yourself losing often) solves the problem brilliantly. Use this little gadget to locate your phone with the push of a button. Or, locate your keys using an app on your smart phone. 

But what if your grandparent doesn’t have a smart phone or device? Get them one! My parents love to sit down with their tablet and look at photos of my children that we send them digitally. You can find tablets and e-readers for less than $100 these days.   

As we age, eyesight diminishes and adequate lighting becomes more important than ever. If your grandparent enjoys curling up with a good book, reading the morning newspaper, or knitting sweaters, a stylish night lights that match their decor or motion activated this one in the shape of a tree ring. There are a number of online resources that will help you uncover your ancestry. Once you’re finished, a battery operated Blurb.com or head down to your local drugstore to have your book made.

Do you have an epic entertainer in your family or circle of friends? Come back next week to get great ideas on holiday gifts for your favorite host or hostess.

Compact Fluorescent Lights: Think of a normal florescent light tube, but curled up to fit the shape of a standard light bulb. The best CFLs last 10 times as long and use a quarter of the energy of old incandescent bulbs, according to the federal Department of Energy. The drawbacks of CFLs are that they can be damaged if they are turned on and off too frequently, and they don't work well in the cold so their outdoor utility is limited.

Light Emitting Diodes: Traditionally, LEDs were for power lights on appliances and other limited uses, but advances in technology have greatly expanded their utility, and there are now numerous options for LED light bulbs available to consumers. LEDs are a fantastic value: they use only about 25 percent of the energy of standard light bulbs and can last up to 25 times as long.

Halogen Incandescents: Halogen bulbs are a twist on the old-fashioned incandescent bulbs. They function in essentially the same manner, except the glass globe is filled with halogen gas, which amplifies the light and therefore decreases the amount of electricity needed, hiking its efficiency rating. They aren't as stingy with energy as CFL or LED lights, but work well for outdoor spotlighting.

While modern bulbs cost more to buy than the incandescents you were accustomed to, their increased longevity and efficiency actually lead to big savings in the long run.
