Click Image for more pictures and specifications. New version with smaller back housing. This version is also new with a High beam and a Low beam setting for those with a three position switch in their RV, or other vehicle that needs a high beam (further) and low beam setting. Super Bright 21w LED replaces 30-55w sealed beams with rear lugs. This floodlight is substantially whiter and brighter than your original sealed beam. For RV Flood Light / Docking Fixtures (see notes below) or Tractor or other lights that use a PAR36 Size Sealed Beam.
This LED has two levels of light (three wires, power low, power high, and common ground). If you need a two wire light with a single light level, see the PAR36-18-W-SH. Verify your fixture dimensions prior to ordering.
If you are replacing RV style square inset style docking lights, please read the following:
- There are several fixtures on the market that look the same externally.
- Some fixtures use a slimmer flag glass housing with a replaceable H3 Size bulb that goes into the back of the glass lamp and is held in with a single screw. If you have this style, and want a direct replacement LED Bulb, see our H3-7.5W-CW here.
- This PAR36 bulb can also be used in that type of fixture with some slight modification. This version with a smaller back will fit inside of your housing/cup. The flange of the LED will be thicker though. To accommodate the thicker flange, you can use longer screws (size 10-32 x 3/4 stainless from your local hardware store) and weatherstripping between the fixture base and mounting bezel to shim it out. Please inquire with any questions.
- This is a direct replacement without modification for fixtures that use a sealed beam type lamp with the same flange thickness (see pictures).
Overall Diameter 4.5"
Overall Depth 2"
Depth back of flange to rear 1"
Flange Thickness 1/2"
21w light pulls 1.7 Amps at 12.8 Volts
Additional Installation Notes:
Be sure to align the orientation notch (raised on the light, inset on the fixture) when installing so the light seats fully into the fixture.
This PAR36 is similar in size the following and more bulbs. The diameter and appliction is the same, but the outer flange may be thicker, and the depth may be deeper on our PAR36 LED and may require modification to install in some fixtures:

Modified to fit in H-3 housing
I wanted the Par 36 LED bulbs as they are much brighter than the H-3 LED conversion bulbs. I went ahead and ordered the Hi/Lo bulb since it was advertised at a slightly higher lumen. Tech support advised me that if I wanted to use the "high" setting that I should only connect the power lead to the one connector tab. (Plus the ground tab.) Not to both the high and low connections. Connecting power to the High tab does power up all of the LED's in the bulb assembly. Once I got the bulbs in hand, I was able to cut off the aluminum flange around the back perimeter of the bulb. This essentially gave The LED bulb a mounting profile that was nearly identical to the original H-3 lens. The modified Par 36 bulbs now fit in the H-3 lens housing nicely without the need for any extra thick gasket material.
