In one sentence, describe what the following article is about: Almost all ballasts sold today are electronic, and they can range from $12-$200 USD, depending on your light. Use the old ballast to determine the exact wattage of your new one. Ballasts can be found at most major hardware stores. When buying, you'll need to know your light’s wattage, the number of bulbs it has, and the wiring system on the old ballast.  Make sure your light fixture isn’t using LED bulbs since they do not use ballasts. Check that the bulbs you’re using are compatible with the ballasts you buy. Magnetic ballasts are not sold anymore, so you may need to change the type of bulb.
Summary: Buy a new electronic ballast suitable for the wattage of your lamp, using the one you removed as a guide.

Give the person something pretty they can touch, feel, and, if you’re lucky, tuck into their pillow at night. It's best to write on paper that has either a simple (such as white), calming (for example, cream), or sensual (such as flesh-toned) color. Selecting high-quality paper will add a nice touch and show how much care went into writing your letter.  If you don’t have any stationery, a piece of plain or notebook paper will do fine as well. The message is definitely more important than the type of paper you write on. You can make regular paper look old or even make your own paper if you want to do something fun. Use either a black or brown ink to keep the writing grounded and classy-looking. Avoid “teacher colors” like blue, green, and red that will make it look like you’re marking up a homework assignment. Address the person as “beloved,” “dearest,” “beautiful,” “most cherished,” or, if appropriate, a pet name. If you are already in a romantic relationship, you can say “my” (for example, “To My Dearest ____”), but don’t do this if you’re using the letter to confess your feelings—it could come across as presumptuous and territorial. Instead, use something more detached like “To The Lovely ____,” for example. Date your love letter (month, day, year). This is a memento of your love that will be treasured for years to come. The date is important, and will help bring your love back to the moment he or she received the love letter from you. It is bound to be read over and over again, so be okay with some phrases from this time in your life that you put in the letter being quoted to you later. Use your draft letter to create your final letter. Make sure there aren’t any smears or marks on the paper and that your handwriting is legible. Penmanship is important here so take your time writing, and try to make each letter as neat as possible. You want your love to be able to read and enjoy looking at your love letter. This is your final goodbye. Suitable sign offs include “Yours,” “Yours Forever,” “XOXO,” “Kisses,” “All My Love,” and “Love Always.” If applicable, include a pet name, inside joke or even a reply to a long-unanswered question to make it more personal. If you want to be a bit more romantic, try a simple but passionate farewell. "With undying love" or "Forever yours" can work well. You can include something special with the letter as an extra token of your love. This may be flower petals, a favorite teabag, even perfume or cologne sprayed on the paper. You can also trace a hand on the back of the letter or leave a lipstick kiss on the paper. Fold the letter with the text on the inside, and place it in an addressed envelope. You can choose an envelope that matches your stationery for a beautiful effect. If you want, you can make the envelope or even fold the note itself into an envelope.  Alternatively, roll the letter up like a scroll and tie it closed with a piece of nice ribbon or string. A romantic stamp, such as the Garden Bouquet stamp, can add a lovely embellishment to your envelope. If you want to, put the stamp upside down, which customarily means, "I love you." Mail your letter through Special Delivery if you really want to get your loved one’s attention. Surprise can enhance the message and make the experience more emotional and memorable for your significant other. You can also choose to hide the letter under a pillow, in a drawer or bring it in on a plate with dinner or breakfast. You may want to wait a little while before you send out your letter. After you have finished, put it away and check it before it is time to send it out. Look for errors and make sure there is nothing that you will regret later in there. Then send it out, and be prepared for a passionate response to your labor of love. Don’t make this a one-time event. Make a habit of writing love letters to the person you care about for birthdays, anniversaries, time spent apart, time spent together or no particular reason at all. The more you do, the easier love letters will be to write and the more meaningful they’ll become.
