One of this season's Spring boat upgrades was to lose the power-hungry Halogen spreader light and the portable fluorescents I've always used for night fishing and go L.E.D.
I wanted a light that would not consume much power (like the 55W Halogen certainly does). and also would not interfere with my AM radio reception (like the fluorescents always did) - so I can hear my Metsies night game broadcasts without it sounding like the Martians were attacking.
So after an extensive search I settled on the newest piece out there, the Hella "LED Mega Beam."
After installing & using it, I have the following observations:
1/ Its every bit as bright as the single 55W Halogen it replaced - an impressive surprise
2/ The color temperature of the light is a pleasant blue-white - a very welcomed change
3/ It burns spit for power @ 0.58A/hour
4/ After installing it and firing it up, I switched on the AM radio - mucho interference.
Darn. (Not the actual word I used).
So I e-Mailed Hella Customer Support - who took a week to get back to me. I had actually forgotten about it, and was resigned to living with the AM radio interference, due to what I saw as the usual field non-support. Pretty typical of my experience with the many other vendors of marine equipment I've dealt with over the years.
Not so with Hella, because sure enough a week later a rely comes back from their customer service people - I guess they were initially somewhat sceptical of what I told them, but after using that week for further lab testing, much to their credit, they found that the light did indeed emit RF interference in the 1 megahertz range. Since AM radio is broadcast from 0.54 to 1.6 mHertz, there was little doubt that the light was the culprit.
This was reinforced by the fact that I had already rewired the radio to move it far away from the light's power feedwire, and had changed the battery system that the AM/FM radio draws from. Additionally I had spoken with several electrical engineers at Brookhaven National Laboratory (some of my better business customers, truth be known) and they gave me some quality pointers on using clamp-on ferrite RF eliminators to attenutate the interference. Well, none of that stuff worked - so the problem was obviously on Hella.
So anyway, Hella stepped up to the plate and confirmed that their product was not what they intended, that they would immediately redesign the internal power board to now include RF suppression in the 1 megahertz range - and here's where it gets good - umprompted they volunteered to replace my piece with a newly redesigned unit - as very soon as they can get the running change into production - maybe 45 days.
Good enough for me. And good enough to earn my respect as a stand-up company that really does understand the value of end-user field feedback.
BTW, the light never gave so much as peep anywhere in the FM band, the interference is strictly on the AM side.
Additionally, this is BY FAR the best piece of work I have ever seen in a marine light. The housing is a clamshell of HEAVY cast aluminum and wieghs far more than it looks like it should. Just holding it in your hands will convince you of its overall level of quality - a super piece of work - now to include the RF suppression that it should have had to begin with.
