GRV Ba15d 1142 1076 LED Bulb 4W 56-2835SMD Super Bright AC/DC 12V-24V 40W Halogen Replacement for RV Trailer Camper Motorhome Interior Lights Cool White Pack of 2

Replacing the halogen bulbs with the LED helped, among other items, reduce heat output in the camper. Brightness is a plus also.

Product very easy to install for price. Made a huge difference in our fifth wheel with lightning and saving on batteries.

Arrival date was originally Friday/ Saturday , products showed up the following Tuesday. My customer’s vehicle was tied up those extra days. Made my company look bad

These appear to be well made LED bulbs using the 5050 warm white LED modules. These bulbs are polarity sensitive so if they don't light at first, remove the bulb from the socket, turn 180 degrees and reinstall. The color rendition is a bright white and doesn't have that bluish tint that is sometimes seen with LED bulbs. These bulbs are designed for 12V DC operation only. The current limiting is performed by fixed 100 ohm surface mount resistors meaning that the current will increase (and brightness) with increasing voltage. At 12 VDC, the current draw is about 230 mA for a power consumption of 2.8 watts. At 14 VDC, the current is 360 mA for a power consumption of 5 watts. At 16 VDC, the current is 582 mA for a power consumption of 9 watts (along with an ever so slight aroma that goes along with toasty hot electronics so the prudent experimenter immediately turns down the voltage). Keep this bulb at 14 VDC or lower or you may let out the magic smoke. Once the magic smoke escapes your electronics, you can't stuff it back in and it won't work anymore. I would have given these five stars if they had included the circuits to regulate current like the Brightech LED bulbs that draw constant power (and brightness) from 10 VDC to 30 VDC. On the other hand, these bulbs are dead simple so the only likely failure will be the LEDs themselves. We'll see how they do in the overhead fixture above the dinette in my RV.

Very good product

Did not work with my car

Up graded some lighting in my camper. the bright light is great, but one of the bulbs only lasted two minutes.

These bulbs were much brighter than the original 12W incandescent bulbs.

installate sulla barca perfettamente funzionanti

I put a pair of these lights in my semi truck dome light, they are sooo bright that I only turn on one of them!! A pair of these would light up a large room in a house!!!! So if ur looken for a really bright interior light, these are the ones u want!!👍🏽👍🏽👍🏽

Replaced my interior RV lights with the GRV Ba15d LED lights.Nice and bright, not like a poorly lit cave anymore!

all good
