Water filtration

https://a.co/d/4c6qJzV

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

https://a.co/d/8OnnCio

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

    So looking at what you sent only the middle light bulb is actually any more efficient the other two are ether equal or more expensive in electric bill.

    Though thank you for adding these. While in my personal case RGB overweights the one that would be a tad cheaper. For others it may be a definite option for those without as serious as eye problems. As I do.

      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.
