How much will 4 cfl 26 watt bulbs run me monthy on 24 hrs.

It all depends on which light kit was installed on your fan. As you described the fixture as requiring a "light bulb" meaning a singular bulb, Minka Aire usually uses several different types.

The most common is either a 40-watt or 60-watt Candelabra Bulbs.
(The designation "Candelabra" refers to its screw base. You can buy these in clear or frosted, torpedo or globe with a straight tip or curved. Etc.
Here's an example of a torpedo globe:
Sunlite 60 Watt Torpedo Tip Chandelier Candelabra Base Frost 48 Pack
And here's an example of a Candelabra globe:
Sunlite 60 Watt G16 5 Globe Candelabra Base Clear 48 Pack

Some of their fixtures use a 50-watt Mini-Can Xenon Bulb.
Satco S1914 50W MINI CAN FROSTED 120V

And other use a 3w CFL Medium Base Bulb.
3W CFL Deco 2700K Medium Base

When installing a CFL, Halogen or Xenon bulb, I recommend cleaning the glass with an alcohol wipe to remove any oil from fingerprints. Due to the very high temperatures these lamps operate at, the oil from your fingers will cause a hot-spot on the glass and can shorten the life of the bulb dramatically.

If none of the references I offered match the bulb in your actual fixture, you might be able to more closely match the fixture from one on the following page. The recommended bulb for each fixture is listed in the description of the fixture.

And as always, NEVER over-lamp a fixture with a bulb rated at a higher wattage than what's shown on the base of the fixture. That is, never use a 60-watt bulb in a fixture rated at 40-watts. The additional heat of the bulb may harden the insulation of the wiring in the fixture creating, causing the insulation to fail and create a fire hazard. Also for fixtures located tight to the ceiling, higher temperatures can dry out the gypsum ceiling material, causing it to crack and deteriorate.

it should tell you on the unit what watt not exceed

The bulb fixture itself should tell you what the max wattage is that you can put in there but they are normally at a 60watt limit.

This timer is rated for incandescent light bulb only.
With 40 watt minimum.
With 100' maximum distance between bulb and timer.

EJ351 is not rated for CFL bulbs (or motors etc).
CFL bulbs are considered inductive loads (same as motors), while incandescent bulb is resistive load (same as a heating element).
Both types of loads use electricity differently.
Programmable wall timers are not ordinary on-off switch... unless you use the override switch.
... instead timers control electricity with electronic circuit board.
So when the manufacturer designs the electronics inside the timer, the design must anticipate how the electricity is used by the load.
Older designs like EJ351, and some modern timers, are not rated for CFL.
... however most newer timer designs are rated for both resistive and inductive loads.
Always read the specification sheet for load rating before installing programmable timer.

Simply use regular bulbs. It sounds like it is switched electronically probably via a dimmer. If the CFL lamps are not specifically labeled dimmable they won't work. I have seen the LED lights work where the CFL lamps will not. If you want to use CFL then replace the dimmer.

You would be better off getting 3 40watt daylight bulbs.. extreamly bright low cost and wont cause any harm to your fan.. hope this helps :)

are you using one of those florescent bulbs? They generally can't be dimmed.

The bulb is replaceable. You can get the bulb at radio shack and also from the company website.
