I replaced the bulbs in our EggCamper with LEDs about three years ago. I got them from SuperBrightLEDs.com. But, I had to do a couple of things to make them work reliably. They were a flat rectangular circuit board containing 36 leds with a connector on the end of a wire. I had to epoxy the connector to the back of the cirucuit board and before I installed the bulb, I added a voltage regulator to each fixture. It was a major project, and each led bulb was about $18.
More recently, I got some replacement LEDs for my (I'm embarrassed to admit this) for my not-molded-fiberglass Trail Cruiser from HQRP via Amazon ( HQRP 4-pack T10 #194 #168 W5W Wedge Base 30 LEDs SMD LED Bulbss Warm White Replacement for Malibu Surface Mount / Tier / Walk Lights plus Coaster - Amazon.com
)... much cheaper. But, the light
is more white than I like, in spite of the "warm white" designation on the Amazon page. They're very bright and the white is tolerable, but I wish they were a bit warmer.
There are a couple of things to look at when buying LED bulbs. The color of the light
from "white" LEDs can be harsh. I prefer warm white light for all but the most detailed work. Also, look for the voltage range spec. Look for bulbs with a range extending to 30 volts, which means that the bulb has a built-in regulator. Many LED bulbs list the voltage as 12 V, which means that the bulb probably doesn't have an integrated voltage regulator. The regulator is important because the charging voltages from on-board converters and battery chargers can reach to 15 volts and shorten the life of the LEDs.
Byron, Although EggCampers are electric, with an 80 amp/hour battery, LED lighting
and some conservation, I used to camp weekends, off-grid without recharging. The biggest draw is the refrigerator
, which is really pretty efficient. I've since added solar
, but I suspect that 3 days would be possible, and longer if you hook-up to the TV for an occasional re-charge.
