So the question here is which one is not like the others? I’ve had decent results with the Cowboy studio 45 watt CFL bulbs ($21.44 = four pack), but I was trying to figure out why the ALZO 45 watt CFL bulbs are ruffly twice the price ($40.50 = four pack). So I went ahead and ordered a four pack of the ALZO bulbs to test them out.

Both the Cowboy studio and ALZO bulbs claim to be 45 watts at 5500k color temp and an approximate incandescent equivalent value of 200 watts of output.  But looking at the Cowboy studio CFL (above left) you can already see that the bulb is significantly smaller then the ALZO bulb (above right) even though the labels indicate that these two bulbs are equivalent. I have the distinct impression that one of these distributors is modifying the facts a little bit.

When you place the Cowboy studio bulb in the middle of the ALZO 45 watt CFL bulbs it’s very easy to tell that the CFL puts out significantly less light. Hopefully in the next week or so I’ll have a chance to setup an actual test rig and find out how much of a difference there is between the bulbs. No matter what the final results ending up being, it’s pretty easy to see that the ALZO 45 watt CFL bulbs are worth the extra $5 a bulb for the performance. If I had to guess I would say the Cowboy studio 45 watt CFL bulb only puts out about 120 watts of equivalent light which means it’s probably a re-branded 32 or 27 watt CFL.

One thing is clear, the cost of each of these CFL’s does reflect the amount of light output. I’ll have to dig out the old voltmeter and amp meter to see what’s really going on. Once I have a chance to run some tests I’ll post a video. It should be interesting to see the results.
