I'm sure a a 6500K 26W spiral bulb would work better and only cost you 5$ at any local hardware store.
Mushrooms are not plants. Just feed them what they get from the fluorescent spectrum @6500Kalvin.

Lighting Requirements of Mushrooms
Some mushrooms, such as the Agaricus species commonly found in grocery stores require no light at all. However, those commonly grown by hobbyists, such as Pleurotus ostreatus (Oyster Mushrooms), Lentinus enodes (Shiitake), Psilocybe cubensis, a hallucinogenic mushroom, and Hericium erinaceus (Lion's Mane) all require light to produce abundant, normal sized fruits. Experience has taught us that the light best suited for primordia formation and the development of fruitbodies is bright light with a color temperature of 5,000 Kelvin to 7,000 Kelvin. Fortunately, this type of light is easily obtainable at your local home improvement center in the form of fluorescent fixtures. For a small terrarium as described in this chapter, a single CFL (compact fluorescent) that screws into a standard light bulb socket will work very well. These can often be found in grocery and drug stores in every neighborhood. 15 watt CFLs will do the job well, but the package will probably have a large 60 stamped on it, indicating they produce light "equivalent" to a 60 watt incandescent light bulb. They're referring to lumens of output, not the frequency. Incandescent light bulbs are the worst possible choice for growing mushrooms, since they emit a 'red' light in the 3,000 Kelvin color temperature range.
The higher the color temperature, expressed in Kelvin, the closer to the 'blue' end of the spectrum the emitted light is. The lower the color temperature the 'redder' the light is. If you have a choice of fluorescent lamps, purchase those labeled 'daylight' since these have a somewhat higher color temperature than cool white. Daylight, sometimes called 'natural daylight' fluorescent tubes generally emit light in the 6,500 Kelvin range, while cool white fluorescent emits light at around 5,000 Kelvin. If you have several terrariums stacked or otherwise near each other, you can use larger 2 to 4 tube fluorescent fixtures. These come in 48" and 96" lengths. Place the fluorescent lamps as close as you can get them to your terrariums without causing excessive heating. Species such as Shiitake and Oyster mushrooms prefer to fruit at temperatures in the upper 50's to mid 60's Fahrenheit (15C to 20C), while Psilocybe cubensis prefers to fruit at a temperature in the mid 70s to about 80 Fahrenheit (23C to 27C) Most mushroom species don't mind a slightly warmer temperature during daytime than at night, so if your grow room is a bit colder than the temperature ranges given above, a little warming from your lights during the daytime won't hurt at all, provided you don't let the air in your terrarium get too dry. For cakes, try to keep the humidity above 95%. Cased substrates are a bit more forgiving, but still try to keep your humidity above 90%. 12 hours on, 12 hours off has proved to be a great combination over a wide range of species. Of course, if you have a bright window near your terrarium, that will suffice, but direct sunlight for more than a few minutes per day should be avoided. Disregard outdated advice in old books which is constantly repeated on the internet to colonize mushroom substrates in total darkness. Experience and rigorous peer reviewed studies have proved that exposure to low level ambient indoor lighting during spawn run and substrate colonizing will speed up the process, leading to full colonization up to a few days earlier than the same substrate would if colonized in darkness. In addition, mushroom mycelium develops a day/night circadian rhythm, so exposure to light from day of inoculation sets this process in motion, leading to earlier fruiting and harvest.

yeah just get the bulbs for like $2 a piece at lowe's, they work great!
you don't need that other shit and i don't even think that's the right kind of light you need anyway

Thanks for you're input 
None of the above. You want daylight spectrum lights. They'll either say daylight on the box or sometimes they have the color temperature listed. Look for 6500K. RR

like RR is saying u got to have the right spectrum of light for our friends to grow. i've been growing with an LED fixture from my old salt water tank that i used to grow corals with for about a year now and it works just fine. that said, if i didnt already have the fixture i would be using the CFL bulbs everyone else is talking about.
