Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

HONDA makes a halogen round light for 60 bucks.  It's OK, but lets be real here, LED's are the Future, and they have lots of light for a little juice, so why isn't the Honda Snowblower equipped with one ?   I found a LED that has 5 - One Watt LED's, and throws 400 Lumens that would look great, if it'd work. It is a 12 Volt  utility light, for about the same price as the Honda OEM that I don't like.  I'm no Electrician, so I'm looking for advice here from somebody who is.  Also if not this light, is there one that would work that is an LED ?

I think the comments about leds producing a lot of heat in this application are totally misleading. I have quite a few led lights including Vector 26 bulb work light. It produces no heat. The bulbs are set in a plastic, the lens is plastic. I was discharging it the other night and it was on for 3 hours. There was no heat being generated by the light. Maybe there are some application where the leds do produce a lot of heat. But I have never seen a 12V DC unit that produced any.

http://vehiclelight.com/39993.html   Here is the light I am interested in using, if possible.  I am not concerned about heat, I am concerned that the stator on the one cylinder 9 HP Honda  engine, that generates the electrical power,  may produce too much power for a light unit that draws less than 2 amps.  Anyone who has used a battery powered LED would wonder that heat could ever be a problem.  I use a head band light with three LED's when I am out at night with the snowblower and it is very effective.  The unit I am intending would mount on the panel above the engine, between the handles, and flood the area ahead with 400 lumns of light.  In th end I may just have to gamble, and buy the light, connect it, and see what happens.  Thank you all for your opinions.

Go here  http://www.candlepowerforums.com/vb/forum.php  and ask these guys. They really know everything about LED lights and what you will need for your application. They may have a better solution or tell you how to make that light work with your snowblower.

Ok here goes: http://patmullins.com/ledlightmyths.html#toc2

"LEDs produce more light per watt than an incandescent bulb.  But most of the watts they consume is still converted to heat, and if not dissipated, will drastically shorten their life.  Heat doesn't radiate from an LED, so it must be conducted away, usually into an exchanger to free flowing air.  The LED junction must operate below about 85°C."

And from Wikipedia: http://en.wikipedia.org/wiki/Light-emitting_diode

"Like other lighting devices, LED performance is temperature dependent. Most manufacturers’ published ratings of LEDs are for an operating temperature of 25°C. LEDs used outdoors, such as traffic signals or in-pavement signal lights, and that are utilized in climates where the temperature within the luminaire gets very hot, could result in low signal intensities or even failure.^[36]

LED light output actually rises at colder temperatures (leveling off depending on type at around -30C^{[citation needed]}). Consequently, LED technology may be a good replacement in uses such as supermarket freezer lighting^[37][38][39] and will last longer than other technologies. Because LEDs emit less heat than incandescent bulbs, they are an energy-efficient technology for uses such as freezers. However, because they emit little heat, ice and snow may build up on the LED luminaire in colder climates.^[36] This lack of waste heat generation has been observed to cause sometimes significant problems with street traffic signals and airport runway lighting in snow-prone areas, although some research has been done to try to develop heat sink technologies to transfer heat to other areas of the luminaire."

Nothing in the above says anything about LEDs producing a lot of heat.   On the contrary.  Their lack of heat in cold climates seems to be an issue.   I have exterior LED Christmas lights that don't even melt the snow off of themselves.  So, where's the heat?

LED lights run hot but not like halogen lights the above article explains it. If that isn't good enough then not much left to explain.

We're talking about heat in practical terms. He's talking who knows what. I love this "I think heat is a relative term. My Nitecore D10 actually produces a lot of heat for it's size, which is a single Sanyo Eneloop AA battery. That doesn't mean much compared to a human hand. But if you take off the heat sink the bulb will not last very long without burning out. He seems to be one of those persons who reads a lot of information on the internet and then thinks he has practical useable knowledge on a subject. There is a city near where I live that installed LED traffic signals to save money on electricity. Unfortunately they are now spending more in labor to keep the lights clear of snow and Ice than they are saving on their electric bill.

I just put a rechargable 1 million watt lantern lite on mine. You can put 2 on yours if you wish. I mounted mine on my handle bars. If you like led lights you can find those too. Get the rechargable ones. The wire you normaly use  to power your old light ,you use to charge these lights. Just splice the charger wires to your blower wires. You can put a switch between them . If your snow blower does not have a provisions for a light. You can run off the battery in the light.
     A million watt lantern light is more than enough lite.

The LED lights don't give off a lot of heat, but the LED (diode) itself does get very hot, and, as mentioned, won't last too long if it doesn't get rid of that heat.  Think of the head of a pin getting red hot - it won't throw off much heat, but can be very hot and easily destroyed with that extra heat. 

You will find a HUGE range in LED prices, and in general the price gap is due to the more expensive lights having better heatsinks and better reflectors.  A $60 single AA-cell LED light will probably throw more useful light than a $10 3D-cell LED flashlight, be much more efficient and much more durable, so buyer-beware.  Most of the good LED lights can't be found at your local chain store, although they are getting better.  ChinaMart now sells Energizer LED headlamps that put out decent light for under $20, although they are still a far cry from the good $60 LED headlamps in terms of weight, efficiency, durability and light output.  Also at ChinaMart you can get a Black&Decker LED spotlight for under $20 that will out-throw many rechargeable 1-2mcp spotlights, is half the size and weight and will run 20hrs/78hrs on high/low on 4 C-cells.  However, for the good stuff, you generally still need to go online to mfrs. like Fenix, 4Sevens, Nitecore, Peak, HDS, etc.

LED technology is definitely getting better.  In many cases it outperforms traditional incandescent lighting, although incan lighting will always have its place (warm light, glow, etc.).  Also, LED's thus far don't lend themselves well to interior room lighting, in part due to the traditional light fixtures themselves.

Btw, my 2AA Fenix TK20 easily outperforms my 3C Maglite in throw, spill, light quality, and battery life, and is more durable - however, Maglite is slowly catching up with their latest LED lights.
