    Well thank you, Bernard, on behalf of the homeless and struggling people of England.

    And seriously my final question: is it going to be a problem if I use the 3W globe-shaped bulb (57-6545) rather than the 2W tube-shaped one you mentioned? Presumably just means it should last longer as it is underpowered? P.S. Will get a pic up when done!

    You, sir, are amazing. I offered a tenner at the beginning and I'd be delighted to send you it. Wanna PM me your email address for paypal-ing?

    This is ace! Just one more thing: all the 20mm glass slow blows are 250V rated. With these powers... Line 1: 29 2W bulbs = 58W / 250 = 0.23A Line 2: 25 2W bulbs = 50W / 250 = 0.2A Line 3: 15 2W bulbs = 30W / 250 = 0.12A Line 4: 15 2W bulbs = 30W / 250 = 0.12A Line 5: 11 2W bulbs = 22W / 250 =...

    Sweet. So that VTX box then a 2.5mm cable ??? diameter to junc box then five lines of ??? diameter cable wired in parallel. Does that not mean each branch will only get 12/5V = 2.4V? Sorry for being dense. Also, if I was going to fuse each line, what sort of fuse would I use? I can't believe...

    Okay, so I'm a little confused. If I was to run these on AC for bulb life at 12V then 104 Bulbs at 2W is going to be 208W or 17A to the junction box then: Line 1: 29 bulbs = 58W Line 2: 25 bulbs = 50W Line 3: 15 bulbs = 30W Line 4: 15 bulbs = 30W Line 5: 11 bulbs = 30W Also, 12V 200W AC...

    Cheers dudes, I'm gonna read through that, Bernard, in a couple of hours when my heads a bit clearer! Adam, they're gonna be in a shop window display. Open fronted letters on plywood so quite a lot of air circulation. I was thinking i'd rather allow for the higher power bulbs but then have...

    Thanks for your reply, Adam! Just think it's gonna look a lot better with more traditional lamps. LEDS might look a bit 'school project'! No they can run as a string no problem. Problem with those top lamps is that they're only 0.3W which isn't gonna be very bright at all. Even with 104 of...

    I'm making some marquee-type light-up letters like this:http://bit.ly/2avcDhJ. I'll be using a DC current with little MES bulbs like this: http://bit.ly/2aKpIVr (table of current/power/voltage at bottom of the page). Want the highest wattage ones practical and all bulbs to be the same...

    104 of 12V LED G4 Bulbs wired in parallel

    Hi, I'm making a display light set up like this kind of thing: There will be 104 bulbs in total so I have opted to use 12V G4 DC LED bulbs in G4 lampholders. It doesn't need to be super bright so was going to use 1W LEDS rated at 12V. Obviously will wire them in parallel. Just...

    Roof purlin sizing? Calcs and/or where to get them done?

    Hi! I'm putting a roof over a garage. The double pitch roof spans 5.7m with 35° pitch. The rafter length is therefore around 3.5m. The purlins will be around 1.5m from the apex and around 2m from the base of the rafters. The purlins span 4.2m between the supporting walls. They will be made from...

    Lean to extension over outside wall... weep holes inside?!

    Lean to extension over outside wall... weep holes inside?!

    Hi! I'm planning a lean to extension on the back of the house. However, the lintels over the exterior doors and windows have cavity trays and weep holes; as does the bottom of the wall. Surely when water trickles down the inside of the cavity it's going to weep into my new inside space! How...

    Hot water from combi now only warm

    Admittedly it hasn't been serviced for 3 years. On the running slow front I'd previously read that but hadn't bothered trying because I knew it normally comes hot even with the bath tap on full (the bath tap is actually a sink tap). I just ran the water for the washing up though and I'd left...

    Hot water from combi now only warm

    Hi all! Right, about a year ago I had to replace the diaphragm on my boiler (Ravenheat CSI/HE) because the water was running hot then cold (and eventually just cold). It worked and I've had hot water to this day! However, just recently the water has been only warm - warm enough for a bath...
