LDT photometric data files have the .ldt filename extension. In 1988 CIBSE introduced a photometric file format called TM14, but this need not detain us. The format has not caught on in the lighting industry and in our many years of experience, we have never known a customer ask for a TM14 file.
Generally a letter of intent is not a legally binding contract. It just lays out the terms of the agreement so that both parties can see if they agree with the terms and are ready to sign a contract. The best way to write a letter of intent is to be specific on each of the points of the agreement.
Your letters do not need to be long and you do not need to write more than three or four times a year but please do write. You can use our special writing paper or write online (www.compassion.ca/write). Some hints that we hope will help are: 1  Keep your letters simple and not too long. This helps you get to know your child and helps them know what to write to you. 2  Occasional photographs and postcards add interest, and give something else to talk about in the letters. 3  Remind your child that you are praying for them.
