The "Light Hammer" seems interesting, and I like Jeff, but his marketing is trending towards snake oil..
Well I don't have a position on which bulb is better, because I have never seen a SensiBulb. You did an excellent comparison, but the light hammer was not included. I saw it has a warm light and is bright so I thought I would try it.
I can't agree that Jeff is a snake oil salesman. His bulbs do work and work nicely. I emailed him, and I point blank asked him how his products compared to SensiBulbs. He replied saying that the SensiBulb in an excellent product, and gave me some pros and cons of that and of his bulbs. I can't independently verify or deny his claims, but I thought his comments on his bulbs and the Sensibulbs seemed fair and honest.
Let's not forget that Practical Sailor recently rated the Sensibulb day light version (2950 color temp) at 150 lumens..
The Light Hammer is 3000k and roughly 120 lumens. So, is the light Hammer really the worlds brightest warm white G4 bulb? Hmmmm.....
Jeff did say that SensiBulb does not rate their bulbs in lumens, and he guessed at what he thought the output is. I didn't ask about the review, because I did forget.
For $35.00 I would still consider the Sensibulb especially when you've already stated that the beam width appeared narrower..
I didn't realize the SensiBulb was $35.00, I thought it as closer to $50.00. My comment on the beam spread was in comparison to Jeff's 10 LED array in red, not to a SensiBulb. The light hammer did light my dining room nicely, and after I try it on the boat I'll post an update.
Even the original warm white Sensibulb, with 2650 color temp, is both brighter and significantly warmer. 3000k is not really all that warm when compared to 2650k..
If you call Nick at Sailor's Solutions and tell him you read about the Sensibulb on one of the forums he will immediately knock 10% off the price.
Maybe I'll order one and give it a try. The numbers do look favorable. I'll put them next to each other, switch back and forth and see what differences I notice.
