That's why if I ever buy another computer for simple tasks to buy a tablet and perhaps by a solar panel to charge it instead of using the home electrical outlet.
So to with the LGPA75U I have it uses less watts than the old CRT HD TV I have.
My dream or plan ? is to have lower power consumption electronics so I can buy a deep cycle battery and use a solar panel.
Yes you could buy the 2500 Lumens 720p OPTOMA HD600XLV for £270 but ?
It's a bulb projector
I know, if it dies in 3 or 5 years trow it in the trash, but think about all the electrical power it consumed, and ? not just the new bulb costs but if it's not covered under some protection plan then think about the color wheel costs.
Yes, some have said the cost of bulbs are coming down for the bulb projectors but they don't often think of all the other associated costs like the color wheel, and power consumption.
Yes, those bulbs in those bulb projectors use up a lot of watts not counting the other electronics in the projector
that needs power.
Yep, power consumption's one reason to replace the CRT. It's about 3kWh every 10 hours, which is about 38p @12.64p/kWh, so about £11 every 30 days if I had it running for 10 hours/day (£138/yr), which I perhaps did until recently when I realised and switched to using the LCD monitor when I'm on my own and sometimes I don't even have that on but just my mini-amp and speakers for some background noise (it's not like I can see the screen whilst I'm on the PC anyway).
The 50" Panasonic is rated at around 130W, so that would reduce the running costs by about 1/3rd, whilst the bulb projector
is rated around 233W. I'm not sure what a decently bright LED projector
would run at.
Anyway, now I'm not having the CRT on so much, the cost savings would not be so much per year whatever I replaced it with, so that's less of a reason to replace it. Most days I might not have it on at all now, or maybe 2-3 hours in the evening for gaming, so if we say 1kWh/day=12.64p that's £46/year). If I replaced it with a Plasma and stopped using the LCD monitor, I might have it on 6hrs/day@130W=9.85p/day or £35/year). A bulb projector
I'd be mindful of the life of the bulb so probably would only have that on 2-3 hours/day@233W=8.8p/day or £32/year but I'd need to buy another LCD monitor to use to avoid using the projector
too much, so that would probably be about £80-100).
Anyway, that's a lot of numbers but it's still hard to calculate accurately what I might save using different devices. I hadn't even considered the cost of the color wheel (is that not an issue with LED projectors?). So I'm hoping that a decently bright LED projector
becomes available for under £500 (preferably a lot less) quite soon but if that's very unlikely, I should probably consider getting a Plasma, even a 1024x768 one, whilst I can or I'll just have to accept that all I'll be able to afford is a 42-50" LCD, which at least will only use about 70W but it'll frustrate me having to spend a lot of money on what I know is an inferior technology and which I'm sure will annoy me somewhat as I'll notice it doesn't look as good as my CRT.
