LED corn bulbs are with fan for good heat dissipation, but if the fan failed, is that affected led bulbs working seriously that means made bulb stop working?

No,even if fan failed, led corn lights are still working well,But what we want you know that the driver we used is with thermal protection fuction, that means when temperature of ambient or led bulb body reach above 95℃,The power consumption will be cut down in half power automatically, meantimes, the brightness also reduced to half automatically till the hot temperature reduced at 50℃,and then the half power and brightness will recovery full power consumption and full brightness automatically! 


So if fan failed in such conditions, This thermal protection function will be always working circularly to protect led lights.

Anyway,The role of Fan is making heat go out rapidly and completely. Actually, Please don't worry about fan,we used SUNON fan which manufactured from Taiwan,as the specification showed that fan operated at 25C degree ( normal temperature),the lifespan continue about 80,000hours,operated at above 50C degree( hostile environment),the lifespan also reach about 30,000hours,And until now, we have not received the complaints about fan problem from our customers..


About the length of LED corn light, Why the temperature must be higher with shorter length and used less SMD?? 

Actually,The truth is the temperature or heat will be increased more if shorter length no matter less SMD or more SMD based on same power consumption, But more SMD will be more better for heat dissipation anyway,For example,30W at 8pcbs with 20 SMD per pcb total 160 SMD without the LED on the front surface,so 30 Watt divide 160 SMD (30/160=0.1875 watt),that means each SMD should undertake 0.1875 watt, While 30watt at 8 pcbs with 24 SMD each,total 192 SMD without the SMD on the front surface,so 30 Watt divide 192 SMD (30/192=0.15625 watt), that means each SMD just undertake 0.15625 watt from total power consumption.


Less power produced less calories heat,0.15625 watt per SMD will have lower temperature than 0.1875 watt per SMD based on same power consumption 30 watt. Absolutely, SMD number have no relations with the length of led bulb,Because total power consumption is still same 30 Watt,it produced calories amount of heat is same no matter how much SMD number or how length size used,just more length or fix a fan will help heat radiating rapidly and completely,keep long lifespan of led bulb for long time useage. 


Well,How about to design one row of SMD per pcb for LED corn bulbs more better solution for heat sinking than double rows?

As above information showed,same power consumption is Not changed,it produced same heat.So that means no matter one row or double rows,it showed same amount of calories heat. 


How do I measure the annual running cost of a 30 W LED corn bulb compared to a 105W Metal halide?

The running costs can be determined by the following.


Annual running cost $ = Wattage /1000 KWH x Hours (Number of hours use per day) x cents per KWH (Cost of electricity)
Example: What is the annual savings when I compare a Dailux energy saving 30W LED corn bulb used for 10 hours per day, 7 days per week, 52 weeks per year, with the cost of electricity at 21 cents per KW Hour ?
Annual Cost for Dailux energy saving 30W LED corn bulb = 30/1000 x (10 x 7 x 52) x $0.21 = $22.932.
Annual Cost for 105W Metal halide lamps = 105/1000 x (10 x 7 x 52) x $0.21 = $80.262

Based on the pathway projects with an average of 50 x 105W Metal halide lamps and a cost of electricity at 21 cents per Kilowatt hour, the annual savings would be more than $2800.00 per year.
