Water filtration
Cost 33$
replacement filters
15-25$
Per year 45-85
2 cases of Kroger water x2 month
3-4$ per case
156$ per year
Filtration system needs replacing every 3-6 months. I based it off; Top Maintenance and Quality Drinking water.
This also reduces trash and plastic waste
Cons
May require buying a set of stainless steel cups for sorting and avoiding taste/texture mixing due to my sensory sensitivities
Now secondly
RGB Bulbs
28$ 4 pack
I need 4 bulbs
Power Consumption at 10% Brightness:
- Typical power usage at 10% brightness: Approximately 1 watt per bulb (for simplicity).
2. For one bulb running 24/7 at 1 watt:
- Daily consumption: 1 watt × 24 hours = 24 watt-hours or 0.024 kWh.
- Daily cost: 0.024 kWh × $0.12 = $0.0029 (about 0.3 cents).
- Annual cost: $0.0029 × 365 = $1.06.
3. For one bulb running 3 hours per day at 1 watt:
- Daily consumption: 1 watt × 3 hours = 3 watt-hours or 0.003 kWh.
- Daily cost: 0.003 kWh × $0.12 = $0.00036 (about 0.04 cents).
- Annual cost: $0.00036 × 365 = $0.13.
4. For four bulbs at 10% brightness:
- All bulbs running 24/7: $1.06 per bulb × 4 bulbs = $4.24 annually.
- All bulbs running 3 hours per day: $0.13 per bulb × 4 bulbs = $0.52 annually.
If all four bulbs are dimmed to 10% and used as described, the total annual cost would be:
- Four bulbs running 24/7: $4.24
- Four bulbs running 3 hours daily: $0.52
- Total annual cost: $4.76
Edit: I’m getting all of this myself
On a dimmer set to 10% all of these bulbs will be more efficient than the RGB ones you linked because they will not have to run a computer and WiFi/BT hotspot in perpetuity. They will simply be on for 10% of the time. You could also probably get some red tinted films to place over the light fixtures.
You’d save about 1.25-1.75
