Hi folks,

I have bulbs in my RV like whats in the attached image - they draw quite a bit of power and I am pretty well off grid with the RV so was looking to replace them with LED bulbs.

Only problem is a can't quite figure out what type of bulb this is?  On the brass base it has CEC1141 TAIWAN2 stamped into it.  I didn't see any bulbs exactly like this, or with this model number, for example, on superbrightleds.com?

Hoping someone can advise best replacement bulbs for low power use!

Thanks in advance!

I agree a 1156 or it's lower power brother (I thin that is a 1411 but do not quote me on that) they are physically identical both fit the same socket and frankly My eyes do not see any difference in side by side testing. but they run cooler.

The same LED assemblies replace both.. Watch your color temp and light intensity. alas I do not know how to converte LED-lumens to Lumens
 
It is an 1141.  Here is a link to the ones I used to replace my 1141 bulbs in my Winnebago;
http://www.rvledbulbs.com/product-p/hp-1141n-10.htm  I think we still get a 15% discount using Forum in the coupon code box.  They provide more light, at least a whiter light than the old 1141 bulbs.  I got some of the more expensive directional bulbs, but liked these so much more, I ordered more for other vehicles.

Thanks a bunch, the 10 pack is a good deal!  15% off that makes it quite compelling!
 
I bought some cheap LED bulbs on ebay, and they were pure garbage. Next. I got a 10 pack from rvledbulbs.com. They did cost more, but after trying them, I ordered 10 more from them.

If it was my RV and I planned on doing a lot of boondocking I would not spend $80 on LEDs. The gain in battery life would be minimal. A better way to spend the money would be to buy another deep cycle battery and add it to the bank. Same price but a whole heck of a lot more time on a charge.

That is reasonable if you are boondocking for a few days. However, If you are boondocking for much longer periods, anything you can do to reduce power consumption is useful. That would include LED lights and a non-powered, catalytic heater.

Yeah, getting another battery is an option, but of course, you know RV's, they do not give you any space for a third battery.  So that just brings up it's own new set of issues.

Also no way can you get a good quality deep cycle battery for $80, at least not here in Canada that I've found.  They are over a hundred here, maybe closer to $150...

Appreciate the thought regardless!
 
I've heard the above opinion that LED's are not effective in reducing power demand one too many times. I just looked at the lights I have on during a bright day; four each that were G4-20, four G4-10 and two reading lights at 20w. Total watts equals about 160 at 12vdc. That is 13A+ for probably 8 to 12 hours per day, totalling well over 100 Amp. hours. The savings (at 75%), neglecting that the LED's will pay for themselves over their lives, is more than equal to that extra battery (and the battery is unlikely to last as long)

Obviously, if boondocking, I could turn off some lights and make the LED's less cost effective, but they still represent a savings overall. AND I DON'T SUFFER THE PITA OF HAVING TO REPLACE ONE OR MORE BULBS A WEEK!

Every bodies opinion is valid because we all have different needs and ways to fill them. We only boondock for up to two weeks at a time. We will rely on a solar panel to recharge us, so if it's cloudy our battery needs to last longer.

We love our inexpensive ebay LED panels and bulbs. 20 units cost under $50 shipped, (less that a grp 24) use a 10th of the power and haven't failed in anyway so far. We went from running four regular bulbs for four hours a night and using 22.4a which is half of our available bank to using four LEDs that use .2a in the same time.  We don't even think about using them any more.

If you do a mix of boondocking and shore power, regulated bulbs may be better for you. I haven't had any adverse effects up to 17v but for some it warms the cheap two sided tape on the panels and causes it to release.

Cob style fit like the original bulb without any tape, so they are easy to change out or move around. I'd do all cobs if I were to rebuy.

When shopping for LEDs, understand that just because one has more LEDs on it doesn't mean it will be brighter. A SMD has one emitter per tiny bulb, a 5050 has three emitters per. so a 24 LED 5050 can be brighter than a 48 LED panel and take up less space. That said, our 48 LED SMF 1210 panels are as bright as the incandescent bulb they replaced.

Color is the last thing. Warm white LEDs are closest to the color of a incandescent. Bright white tends to have a blueish color which can feel a bit brighter than they are. Our smaller dimmer 9 LED cobs are bright white and four of them comfortable light our 25 ft trailer for kicking back, watching a movie, eating, games, etc.

You can even get a 120 LED cob to replace your porch and scare lights. $5 shipped and brighter than what I have now in our porch light for a fraction of the power.
