MR16 halogen lamps with two types of reflectors - dichroic and aluminium. With a dichroic reflector, most of the heat is emitted from the back of the lamp. These should NOT be used in downlight fittings, as they will cause overheating. Dichroic lamps are designed for use in display lighting, where the lamp is in an open fixture so that the heat can be dissipated, and the beam of light does not heat up the object it is illuminating. For use in downlights and other room lighting applications, aluminium reflectors should be used, so that most of the heat is emitted from the front. This will avoid the fitting overheating, which will cause damage and possibly a fire. Plenty of retailers and websites describe these lamps incorrectly, so it is best to check the lamp itself using the simple method shown in the video.

Attaching 8P8C plugs to CAT5e cable. Some additional things that may not be in the video but have been mentioned in various comments: Plugs and cable must be of the same type, in this case CAT5e solid core cable and CAT5e plugs for solid core. If flexible leads were required that will be moved often, stranded cable would be a better choice. The cable and plugs in the video were purchased for an installation of IP CCTV cameras, which are installed once and never move again, so solid core was used for those. For a fixed installation it would be more usual to have wall sockets, however for the CCTV system mentioned, the cameras have sockets on short leads, so the installed cabling has a plug which connects directly to the camera. The recorder unit has sockets so the other end of the cable plugs directly in to that. ► Support this channel: Patreon: https://www.patreon.com/jwflame PayPal Donations: http://xo4.uk/?PPP Amazon: https://amzn.to/30bKt4v (As an Amazon Associate I earn from qualifying purchases) ► Social Media: Twitter: https://twitter.com/jwflame Facebook: https://www.facebook.com/jwflame Instagram: https://www.instagram.com/jwflame/ ► Contact info, sending stuff in: etc.: http://xo4.uk/?YTT ► Cryptocurrencies: Dogecoin DOGE: DShDwFJyXKqCddwVsuCWWYnGpuhFrBMyam Litecoin LTC: LXQ4QRqztUq1KBQccxeLDivrdnas5fcHrc Nyancoin NYAN: KUiaPqoRcNnhXHcfWrgEYD5aZqwocLnrwf Bitcoin BTC: 17JyfSsQuUi1tHow26QxUvsh45kP6vsK63 ► Website - More on this video and many other subjects Website: https://www.flameport.com ... https://www.youtube.com/watch?v=0FtJn1oD0Fw
